4, stiffness and resistance to scratches the surface characteristics of a good engineering plastics, PP board use of glass fiber, metal additives or thermoplastic rubber modified PP Nanhai undertake engineering plastics, turnover MFR range of 1 to 40, low MFR PP material better impact properties, but the extension of lower intensity. Thus, in general PP board environmental stress cracking problem does not exist.
