Predispersed Rubber Chemical Retarder-80

Identification:

Chemical Name: N-Phenyl-N-(Trichloromethylsulfenyl)-Benzene Sulfonamide

Synonym: Pre-Dispersed Polymer Bound Chemical Retarder-80; Retarder E

CAS No:2280-49-1

EINECS No:218-915-0

Molecular Formula: C13H10Cl3NO2S2

 

Properties: Excellent retarder for natural and synthetic rubber, suitable for EPDM, NBR HNBR, obviously delay the scorching

time, but not affect the curing speed. Especially for thiuram vulcanization system, and can be used as the second promoting agents, reduce curing time and improve production efficiency.No pollution, not changing color can be used for light products. Meanwhile, can improve EPDM and NBR the sulfurization cross linking density, improve stretch for stress, reduce the permanent compression deformation. No harmful substances during curing process.

 

Dosage: 0.5-1.5 phr. Active material is as same as DZ-01, but active content is higher more.
