physical property:
white powder, odourless, relative density 5.606, stable under normal temperature. insolubl in
water and alcohol, soluble in acid, alkaki and amkonium solution.
characteristic and function:
1.high activity, even granularity, it's possessed of high dispersing ability, has the good
promotion curing function, improve the cross-link china density of rubber, enable
to make the rubber vulcanization more completely.
2. it can improve the viscidity of rubber compound,and the adhesive force of materials such
as the rubber, steel wire and code fabric, etc.
3. it can make good dynamic performance, make the rubber products with little deformation,
low heat generation, high anti-abrasion. enable to have good anti-oxide property.
usage:
used in rubber, dope cable, porcelain enamel, oil, pottery and porcelain, glass and
other chemical industry.
packing:in polyethylene film bag with outer polypropylene woven bag, 25kg, 50kg, big sack
bag or as required by the customer.
