For co-extrusion WPC, it will not have color fading problem, more anti-scratch, and more stain resistant.
10. What properties will you test for your raw material and end products? Wood fiber: ash content, fiber size, water content.
HDPE: melting index, ash content, physical property test for finish product
End product: melting index, ash content, physical property test for finish product
End product: strength test, boiling test and expansion rate test, temperature cycle test, outdoor UV test
