PP (Polypropylene)

Polypropylene (PP) is a versatile thermoplastic – it is the lightest polymers among all commodity plastics, low density, stress-cracking resistant and the list goes on. Among variety of structures in PP family and its competitive properties with polyethylene can be confusing when it comes to selection. In this guide, get answers to all your queries while looking for a suitable PP grade for your application.

Thermoplastic composite materials often suffer from a lack of fiber-matrix adhesion. A weak interface in these materials results in low stiffness and strength but a high resistance to fracture. On the other hand, a strong interface produces high strength and stiffness but generally low fracture resistance. So, how to overcome this lack of fiber-matrix adhesion? Can fiber surface modification help? Find out all your answers here! Explore the ultimate solutions to optimize matrix / fiber interface in thermoplastic composites and achieve desired strength & stiffness along with fracture resistance in your product.
