- Atactic polypropylene (APP) polymer modifiers are by-products of the polymerization of propylene gas into isotactic polypropylene (used for injection molding and extrusion). APP has a lower melting point and is more compatible with asphalt than isotactic polypropylene.
- Bitumens modified with APP can display improved physical and mechanical properties. The improved properties are only possible if the APP is finely dispersed throughout the bitumen to avoid separation during manufacture and service.
- APP modification of bitumens can impart the following changes in properties:
- increased softening point
- improved ultraviolet radiation resistance
- improved low temperature flexibility
