Polypropylene is available in two grades – Homopolymer and Copolymer. Homopolymer is the harder and more rigid grade whilst Copolymer is more flexible and has better low temperature impact performance.
Polypropylene is lightweight and has low moisture absorption properties which improves product and component stability, whilst also helping with bacterial resistance. Along with excellent acid and chemical resistance, polypropylene can be easily machined allowing the material to be used in many varied industries.
