Application:
1. FST Si69-50E improves the tear strength and abrasion resistance of vulcanizates.
2. FST Si69-50E can improve the reinforcement of the filler, at the same time it can also increase the cross-linking density of vulcanization and reduce the compression set.
3. FST Si69-50E can prevent vulcanization and reduction, so that rubber products can obtain good heat aging resistance.
4. FST Si69-50E is suitable for products such as shoe soles, rubber rollers, conveyor belts, transmission belts, tires, wires and cables.
5. FST Si69-50E is more convenient to weigh and more stable in storage and transportation.
Usage: add it together with reinforcing filler.
Suggested dosage: 1～6phr.
