Designed Polymers for

Bitumen Modification


VESTOPLAST® modified bitumen for waterproofing membranes show outstanding properties like high heat resistance, excellent cold temperature flexibility, high softening point, high resistance to thermo oxidative ageing, high UV-resistance and excellent processability during the waterproofing membrane production.

VESTOWAX® is used to increase softening point and to reduce the viscosity of bitumen.

The unfunctionalized POLYVEST® and the hydroxyl-terminated POLYVEST® HT contribute to reductions of viscosity as well as softening point of bitumen membranes by its typical characteristics. In addition, POLYVEST® HT in being incorporated as reactive component in bitumen systems.
