Properties
Light yellow crystal(granule). Odorless. Specific gravity: 1.27--1.30. Soluble in benzene, toluene, carbon disulphide, acetone and chloroform; Insoluble in water, dilute acid and alkali, partly soluble in gasoline and alcohol. Sensitive to skin and mucosa. Have certain toxicity, good storage stability. The ultra-accelerator is suitable for natural and synthetic rubbers, for instance, polybutadiene styrene, polybutadiene acrylonitrile,
polyisobutyleneisoprene, cis-polybutadiene and latex; can be used as vulcanizator too. Extensively used for cable, medical supplies, rubber cloth, rubber shoes and etc.
Application
A primary accelerator and curing agent for NR, SBR, nitrile and EPDM. The efficiency sulphur content is 11%. Closely resembles Accelerator TMTD in its applications. Have high catalytic action to acids and guanidine type accelerator. Less scorch and blooming, good processing safety. Can be used in CR as an anti-scorching agent and as raw material for germicide, pesticide and medicine.
Used for natural rubber, styrene-butadiene rubber, nitrile rubber, butyl rubber, Super accelerators and vulcanizing agents for cis-butadiene rubber and latex. It is usually used for manufacturing cables, rubber sheets, rubber shoes, inner tubes, and colorful products, etc. Applications in rubber products that come into contact with food.
Packaging
25kg plastic woven bag, paper wilh plastic film bag, kraft paper bag
Storage
The product should be stored in the dry and cooling place with good ventilation, avoiding exposure of the packaged product to direct sunlight. The product with pallet should not be stacked.
