Based on their characteristic microstructure, all POLYVEST® grades exhibit an excellent reactivity and can be used for a broad variety of applications. The unsaturated polymer backbone of all POLYVEST® grades offers the opportunity for various crosslinking options, like sulfur curing and oxidative drying. In addition, the functional moieties of POLYVEST® HT and POLYVEST® MA provide further options for crosslinking and make polymer modification feasible. Due to its rubberbased nature, POLYVEST® ST is perfectly suited as a reactive plasticizer in tire and mechanical rubber goods applications.
BENEFITS AT A GLANCE
- Low viscosity
- Excellent chemical resistance to acids and bases
- High water resistance
