Normally used alone or with small quantities of ultra accelerators in tire compounds or industrial rubber products. Packaging: 25kg bag. Storage: Keep container tightly closed in a cool, well-ventilated place. The recommended max. storage life is 1 years when stored under normal conditions.
requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C for completion, which is uneconomical by any production standards. The vulcanizates thus produced are extremely prone to oxidative degradation and do not possess adequate mechanical properties for practical rubber applications.
WESTCO™ DTDM 80 Accelerator 80% 4,4'-Dithiodimorpholine in an EPDM/EVM binder CAS# 103-34-4. Westco™ DTDM-80 is a sulfur donor vulcanizing agent for low sulfur or non-sulfur curing systems. It provides good heat aging resistance in natural and synthetic rubber when used with sulfonamide accelerators. The dispersion is filtered through a 140 mesh screen during production.
Rubber accelerator TBBS (NS) is the structure of the primary amine, does not exist to produce nitrosamines toxic substances, and it is similar with rubber accelerator NOBS on performance.So it is highly valued applications and its production development speed rapidly.
Properties: Gray white powder (granule). The density is 1.26-1.32. soluble in benzene, CS2, methyl alcohol, acetone. chloroform, alcohol, insoluble in gasoline, water, acid and alkali with lower concentration. Application: Provides fast cure rate and high modulus development in …
Thiazoles--Rubber Accelerator MBTS (DM) 6 Oil content (*) % 1.0--2.0 Properties: A little bitter taste. Specific gravity: 1.50--1.59. Soluble in chloroform, toluene, benzene, carbon tetrachloride. Insoluble in water and ethyl alcohol. Application: Given flat, moderately fast cures in NR and SR. Also used in a wide range of general purpose rubber.
WESTCO™ TBBS Accelerator (N- tert-butyl-benzothiazole sulfonamide) CAS# 95-31-8. It has lower scorch than CBS and can be more safely processed. It has slightly faster scorch than OBTS. WESTCOTM TBBS has high modulus and excellent physical properties, suitable for tire treads and mechanical goods. Solubility: Soluble in ethanol, acetone, benzene, ether, toluene and carbon …
Properties: Light yellow or orange crystal (granule). No poison with a little odor of ammonia. The density is 1.34-1.40. Soluble in benzene, acetone. chloroform, insoluble in water, acid, and alkali with lower concentration. Application: An excellent delayed accelerator.
