TBBS(NS)-80

Description

Rubber Accelerator TBBS (NS) is an exccellent after effect accelerator for NR, BR, IR, SBR and reclaimed rubber, especially suitable for stronger alkaline carbon black rubber. It has exccellent properties of safe processing, scorch resistance , fast curing rate, high tensile modulus, and an ideal substitute for NOBS. With aldehyde amine, guanidines, thiurams, and antiscorching agent PVI (CTP), it can form a good vulcanization system.

Function

JXBHgran TBBS - 80 has a longer scorch time, high processing security and curing speed. It can be used in the low sulphur vulcanization alone, either with dithiocarbamates or thiurams. The vulcanization rate of the compound is significantly reduced after the dithiocarbamate accelerator and the thiuram accelerator is blended. JXBHgran TBBS - 80 has obvious secondary role of accelerating to thioureas, especially in low sulfur rubber, and scorch time can delayed.

Dosage

NR: the main accelerator: 0.5- 1.0 Phr , 2.5 -3.5 Phr of sulfur; Second accelerator: 0.5 PHR , 0.3 PHR of thioureas or thiurams and 1.5- 3.5 Phr of sulfur; SBR: 1.0-1.4 Phr , 0.2 Phr thiurams and 1.5 -2.5 Phr of sulfur.

Application

It can be used in tire, rubber hose, conveyor belt, rubber shoes etc.

Packing

25 kg in carton box with polyethylene bag liner.

Storage

A cool and dry condition, the storage period of one year.
