Polypropylene (PP) is an inexpensive thermoplastic with variable impact resistance depending on the grade. PP is wear-resistant, flexible and can have high elongation, while it also has high chemical resistance.
Applications: Fans, lids, packaging, integral hinges, living hinges, medical tubes.
Behavior: Thick sections of molded PP are vulnerable to sink and bubbles, with shrink and warp also possible. K-Resin is a suitable replacement for living hinges.
