1,3-Diphenyl-2-thiourea DPTU-80GE CAS 102-08-9

This product is used as fast vulcanization accelerator, the critical temperature of vulcanization is 80 ºC, and care should be taken to avoid early vulcanization when mixing. The products obtained are tough and have excellent tensile strength and flexural resistance, but the products will be discolored by light.

Bis hexasulphide piperidinothiocarbonyl DPTT-75GE CAS 971-15-3

DPTT-75GE is used for all kinds of rubber especially EPDM and II heat resistant products such as hoses, seals, sheaths.DPTT has fast vulcanization speed and high scorch safety in natural and synthetic rubber. As activator and co-promoter, it can be used with mercaptans and hyposulfonamides accelerators.

Bis hexasulphide piperidinothiocarbonyl DPTT-70PE CAS 971-15-3

DPTT-70PE is used for all kinds of rubber especially EPDM and II heat resistant products such as hoses, seals, sheaths.DPTT has fast vulcanization speed and high scorch safety in natural and synthetic rubber. As activator and co-promoter, it can be used with mercaptans and hyposulfonamides accelerators.

Bis hexasulphide piperidinothiocarbonyl DPTT-70GN CAS 971-15-3

DPTT-70GN is used for all kinds of rubber especially EPDM and II heat resistant products such as hoses, seals, sheaths.DPTT has fast vulcanization speed and high scorch safety in natural and synthetic rubber. As activator and co-promoter, it can be used with mercaptans and hyposulfonamides accelerators.

1,3-diphenylguanidine DPG-80GS CAS 102-06-7

DPG-80GE is used for various industrial technical products and rubber products containing white fillers.DPG is effective in activating thiol accelerators.DPG has no vulcanization promotion effect on butyl rubber IIR and ethylene propylene rubber EPDM.

1,3-diphenylguanidine DPG-80GE C CAS 102-06-7

1,3-diphenylguanidine DPG-80GE CAS 102-06-7

1,3-diphenylguanidine DPG-75GE CAS 102-06-7

DPG-75GE is used as medium speed accelerator for natural rubber and synthetic rubber, mainly used for manufacturing tires, rubber sheets, rubber shoes and other rubber industrial products.

Di-o-tolylguanidine DOTG-75GA CAS 97-39-2

DOTG-75GA F140 can be used for natural rubber, diene synthetic rubber, DOTG causes a very slow vulcanization start and relatively slow vulcanization rates. The use of DOTG alone can cause severe vulcanization reversion, so an effective antioxidant is required.
