CHARACTERISTIC

-. SUNCUTTOR-90 is composed of organic and inorganic compound contained 65% insoluble part of CS2 and improved curing stability and dispersion.

-. SUNCUTTOR-90 doesn't cause blooming of uncured rubber compound for a long time keeping and leaving alone.

-. Accelerator, sulfur and filler composed with SUNCUTTER-90 scarcely raises migration, discoloration and contamination at a long time keeping.

-. When the temperature of workshop is over 40~50℃ by using the SUNCUTTOR-90, scorch of rubber compound can be prevented and expensive retarder is unnecessary and though it keeps for a long time, it has good properties.(Dividing operation of sulfur is unnecessary)

-. Curing condition is based on the same method for the composition of general sulfur and accelerator.

-. Bonding powder is elevated when it is operated.

(there is no bonding interference with migration of sulfur)

-. SUNCUTTOR-90 gives support to clear color in compounding colored rubber.

-. SUNCUTTOR-90 plays aiding agent in polymer and filler dispersion.(refer data)

-. SUNCUTTOR-90 can save energy in working process.

 

APPLICATION

-. Applies for sulfur compound product with natural and synthetic rubber compounding.

-. Uses for curing stabilizer of tire, rubber hose, shoes and ebonite.

-. Uses for curing stabilizer of dipping products of latex gloves, balloon and nipple.

-. Applies for a long time keeping of uncured rubber compound.

(Don't use retarder at 50℃)

 

 

 

-. Applies for the problems result from blooming and migration of uncured rubber compound.

-. Applies for improving deterioration of physical properties by filer's dispersion.

-. Secured scrap reclaiming for rubber compound.

-. Improves foaming stability, surface flow, cleared color of rubber sponge, arch(insole), and continuous foaming sponge of shoes parts.

-. As applied to shoes parts. It is effective to canvas, topping goods and boots.

(Since it improves scorch stability and a long time keeping is possible, problems don't arise from toe-lasting when shoemaking)

 

REFERENCE

-. It'd be anxious about the fall of effect at using together with common sulfur in the rubber compound.(It's necessary to classify when using the scrap)

-. Curing condition applies correspondingly to the case of common sulfur.

 

 

TEST

It applies correspondignly to the case of natural rubber compounding(scorch time).

NONSCO-A (Retarder)

 

NONSCO-A is a highly effective retarder with a novel chemical composition. IT is considerably more powerful than retrders of the N-nitrosoarylamine type or organic acid, e.g. salicylic acid and phthalic anhydride. Nonsco-A can also be used as a replasticizing agent.

 

PROPERTIES

-. Chemical composition .............................................................. Sulphonamide derivative formulated calcium carbonate(approx. 5%) and mineral oil

(approx.1-2%)

-. Physical form ............................................................................. Fine beige-white powder, practically

non-dusting.

-. Smell ............................................................................................. Weak characteristic smell

-. Density at 20℃(g/㎠) ............................................................... 1.68

-. Melting point of active ingredient(℃) .................................... About 110

-. Solubility of active ingredient ................................................. Soluble in ethyl acetate, benzene,

Methylene chloride, Carbon tetrachloride.

Difficulty soluble in acetone, alcohol,

petrol(gasoline).

Practically insoluble in water

-. Storage stability .......................................................................... according to our experience, product

keeps for at least 12 months without loss

of efficiency.

 

 

EFFECT

Nonsco-A increases the scorch time very much and therefore extends the flow time. As the dosage of Nonsco-A is raised, the retarding effect increases more or less proportionally. The vulcanization time is increased, of course, but to a relatively small extent. Nonsco-A there fore shows very steep advantage of Nonsco-A over conventional retarders since short vulcanization times, if compatible with good scorch resistance, are almost universally desired.

-. NR compounds with sulphonamide accelerators

. Where the vulcanization of the compound is accelerated with, Nonsco-A is 2.5-3.0 times as effective as N-nitrosodiphenylamine ;so the proportion of retarder used on earlier occasions can be substantially reduced.

 

 

 

 

-. SBR compounds with sulphonamide accelerators

. Nonsco-A is about 3.0-3.5 times as effective as N-nitrosodiphenylamine

if the accelerator is accelerator is Vulkacit CZ ; in the presence of Vulkacit MOZ it is 1-2 times as effective.

-. Compounds with Mercapto accelerators

. If the accelerator is Vulkacit DM or Vulkacit Merkapto, Nonsco-A is 4-5 times as effective as N-nitrosodiphenylamine.

-. Compounds with other accelerators

. Here, depending on the accelerator concerned, Nonsco-A is 1.5-3.5 times as effective as N-nitrosodiphenyamine.

-. Compounds with Vulkacit thiuram and a little or no sulphur

. Nonsco-A like most other retarders, has a very slight retarding effect, or not at all, on the

vulcanization of compounds containing thiuram and NR or SBR and containing Vulkacit CZ.

-. Discoloration

Nonsco-A has not influence on the intrinsic colour of the vulcanizates. It also causes no contact staining. Discoloration of vulcanizates to the light can be prevented unless they are pure white, in which case they undergo slight yellowing favourable than such other retarders as N-nitrosodiphenyl amine.

-. Blooming

Non blooming is observed when the recommended additions are used.

-. Smell

The recommended additions of Nonsco-A give the vulcanizates no smell.

-. Physiological properties

The suitability of Nonsco-A for food-related goods has not yet been examined.

 

APPLICATION

As already mentioned, Nonsco-A is used to delay the onset of vulcanization. By adding Nonsco-A, one can control the processing safety and scorch resistance within wide limits without having to change the formulation in other ways. When compounds contain Nonsco-A, intricate shaped goods can be moulded and vulcanized easily.

As a replasticizing agent, Nonsco-A can be used to rehabilitate Mooney, scorch value which have been reduced in consequence of a particular heat history.

In other word, a flow time which has been reduced by unsuitable working process, etc.,can be increased by adding Nonsco-A to the compound.

Nonsco-A is particularly suitable for tire compounds becasue its retarding effect on thiazole accelerators is exceptionally marked. However, it is also suitable for use in manufacturing the other kinds of products, a little or no sulphur. NBR compounds, whose vulcanization can be retarded with Nonsco-A are an exception; here the retarding effect can be intensified by adding sulphonamides, especially

 

 

 

vulkacit MOZ. If magnesium oxide is included, Nonsco-A is also effective inthiuram-cured compounds based on NR or SBR.

If the increase in scorch resistance(Mooney scorch time) is considered in isolation, and not in

comparison with the increase given by N-nitrosodiphenyl amine, them it is found to be greatest in compounds whose vulcanization is accelerated with Vulkacit CA, MOZ,NZ,DM or Merkapto.

 

BEHAVIOUR IN COMPOUNDS

-. Dispersion

. Nonsco-A is easy to incorporate and disperse just with a little additions.

-. Viscosity

. Nonsco-A has practically no influence on the viscosity.

-. Porosity

. Unlike retarders of the N-nitroscoaryl amine type, Nonsco-A imparts no porosity to the compounds processed at high temperatures. This is a decisive advantage in the production of uncured tire treads.

 

EFFECTS ON VULCANIZATION AND VULCANIZATES

-. Vulcanization

. The cure time must be adjusted to the changed rate of vulcanization.

-. Mechanical properties

. Nonsco-A generally has no undesirable effect on the mechanical properties of the vulcanizates. In particular it leaves the tensile strength and resilience properties substantially unchanged. It may increase the degree of crosslinking(and hence the modulus) by about 5-10%. In some cases, though, it has been found that large proportions of Nonsco-A(0.5 parts by weight) slightly reduce the modulus values of vucanizates based on includig technical goods, footwear and footwear soles. Above all, the product is recommended for moulded goods, e. g. those produced by injection and transfer moulding.

PEPTOL-909 (Peptizing Agent)

 

PEPTOL-909 is a very effective peptizing agent which is particularly suitable for use in the mastication of natural rubber at high or low temperatures in the mill or in internal mixers. PEPTOL-909 also aids the mastication of synthetic rubbers.

PEPTOL-909 is easy to incorporate and disperse quickly.

Product safety

Regarding the handling of PEPTOL-909, your attention is drawn to safety data sheet.

PROPERTIES

 

 

 

BEHAVIOUR IN COMPOUNDS

-. Dispersion : PEPTOL-909 is easy to incorporate and disperse entirely satisfactorily. It can be incorporated as the first addition to the rubber, regardless of an internal mixer or a mixing mill is used. PEPTOL-909 can also be added as a SBR-based batch with a concentration of 10% ; this batch can be kept for about three weeks. An NR batch containing PEPTOL-909 at the same concentration is not stabe in storage and therefore cannot be used.

-. Effect : In mastication, the molecule chains of the rubber are split up in a reaction in which atmospheric oxygen participates. This leads to reduce the molecular weight and thus to increase plasticity.

 

 

INFLUENCE ON THE VULCANIZATION AND VULCANIZATES

-. PEPTOL-909 may activate the vulcanization very slightly, but only if it is used at high dosages(1.0PHR, calculated on 100PHR rubber), PEPTOL-909 has practically no influence on the ageing behaviour of vulcanizates which contain the normal quantity of antioxidant. Vulcanizates produced with fairly large amounts of PEPTOL-909, and contained no antioxidants or stabilizers, are less resistant to age. According to the trials completed so far, PEPTOL-909 at concentrations of up to 1.0% causes no discoloration. The odour and taste of the goods are not affected.

 

 

 

APPLICATION

-. PEPTOL-909 is used to accelerate the mastication of NR and SBR and their blends.

 

RECOMMENDED ADDITION

-. The lower figures of the following recommendations can be approached as the temperature of the rubber rises.

. Natural rubber(NR)

2.0-1.0 PHR(80-170℃)

. Synthetic isoprene rubber(IR, SBR)

2.0-1.0 PHR(80-150℃)

COMPOUND FOR RUBBER, PHYLON SPONGE

. Generally, the higher content of synthetic rubber, the worse the test result of adhesion, but in this result, the higher of BR-01, the more improve strength of adhesion, this is that boundary adhesion turns reactive material.

(NBR>BR-01>SBR>IR>NR)

. Antioxdant --- P-wax, Organic Fatty Acid, Paraffin Oil, Polyethylenewax, Naphtha Oil and so on are obstacles in no buffing adhesion

. B.H.T., LSP have no effect on adhesion.

. WS-7350R is chemical inconstant material induced reactive redical of surface of rubber and in case of making contact with Primer, start reaction slowly and form complete bonding strength.

. Must be care about unsteady bonding strength by blooming and maintain right care.

(under curing by oil blooming, sulfur blooming have an effect on bonding strength)

. In case of using mold releasing agent(silicone, etc.) for mold release, must remove perfectly this before bonding work.

(use fluorine releasing agent)

. Prohibit releasing agent (silicone, organic fatty acid) and treatment in working EVA phylon, but in case of treatment, must wash surface by solvent(solvent and watersoluble fluorine releasing agent have no effect on adhesion)

. Up to date, in case of EVA phylon no-buffing, treat UV, but can no buffing adhesion with general line work by improvement compound and adhesives.

 

DIRECT INJECTION(POLYURETHANE SOLE)---- Rubber sole no-buffing work.

. At compounding rubber sole, there are no problems, though forming wedge or middle sole with

WS-7350R.(After treating with the WS-17NF on the surface of rubber no-buffed sole, coat it with the WS-7050S which is added 5% hardening agent, and do heat-treatment for 2 minutes at 100℃ during the adhesion and then shoot PU liquid and form)
