Polypropelene is a homopolymer polyoefin engineering plastic providing excellent chemical resistance and high purity.  It is FDA compliant with better mechanical properties than other polyoefin materials.  Polypropelene is the lightest of all commercial plastics with a good balance of properties, and operates safely at temperatures to 180°F with excellent resistance to many chemicals.  It has high surface hardness and superior abrasion resistance.  Our unique processing technology provides unsurpassed quality in polypropelene stock shapes.  Typical Values
