Application
| Footwear: improve abrasion resistance, cutting and chunking resistance |
| Rolls: improve abrasion resistance, aging resistance, reduced water swell, lower hystersis |
| Mechanical Molded Goods: increased modulus, better heat stability, compression set redcution |
| Hose: improve abrasion on cover, improve heat resistance, lower compression set, improve adhesion to reinforcing elements |
| Solid Tires:improve abrasion, lower hysteresis, higher modulus, improved processing |
| Tires: treads for abrasion, hot tear, carcass for adhesion and filler substitution, break stocks for adhesion |
| Flat Belts: increase abrasion, improved reversion resistance, reduced cost with clay substitution for black, improved cord adhesion, increased flex life and modulus |
It is used to improve physical and mechanical properties of vulcanizates. It is able to markedly improve tensile strength, tearing strength and abrasive resistance and reduce compression set of vulcanizates.
