UV-stabilised for long-term outdoor service, slowing ageing and colour change.








UV Resistant PP is a UV Resistant grade within PP (Polypropylene), widely used in industrial CNC machining due to its balanced mechanical, thermal, and machinability performance.
With UV stabilizers added, suitable for long-term outdoor use, delaying aging and discoloration.
UV Resistant PP grades are commonly used in the following fields and scenarios; our CNC machining services can provide custom parts for these industries.
UV Resistant 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 UV Resistant PP, PP (Polypropylene) offers several other grades with different characteristics. Click to view details.
