Copolymer PP has better impact resistance and stays tough at low temperature for impact-loaded parts.
Copolymer PP is a Copolymer grade within PP (Polypropylene), widely used in industrial CNC machining due to its balanced mechanical, thermal, and machinability performance.
Copolymer polypropylene provides superior impact resistance and does not become brittle at low temperatures, ideal for parts subjected to impact loads.
Copolymer PP grades are commonly used in the following fields and scenarios; our CNC machining services can provide custom parts for these industries.
Copolymer PP demonstrates the following core advantages in CNC machining and end-use applications.
The following are key process points when machining PP (Polypropylene) material, to ensure part quality and machining efficiency.
PP melts at approximately 160°C; use moderate speeds and large positive-rake sharp tools to avoid melting and tool adhesion from cutting heat.
PP has low rigidity; use full-area support and soft-jaw clamping to prevent thin-wall deformation and chatter.
Finish machining with shallow cuts, fast feed rates, and air cooling to achieve a uniform smooth surface and avoid tearing.
PP tends to produce tough burrs; use dedicated scrapers or cryogenic deburring to ensure clean edges.
Besides PP Copolymer, PP (Polypropylene) offers several other grades with different characteristics. Click to view details.
