HDPE RAW MATERIAL BLACK GRANULES USED IN PIPES

The flexural modulus of mineral filled PP can be as high as about 4480 MPa without much increase in tensile strength. Ductility remains below 1.75°F. Impact copolymers with tensile strengths as low as 186 MPa and flexural moduli as low as 689 MPa are not a recent development. Modern polymerization processes can produce materials that can bridge the gap between polypropylene and olefin rubber. In addition to strong oxidizing agents and non-polar solvents, PP is highly resistant to chemical attack. For example, fuming nitric acid or hot concentrated sulfuric acid can degrade PP, but less concentrated solutions are not harmful to PP. Liquids such as gasoline and chlorinated hydrocarbons can swell and soften PP. After removal from these solvents, PP returned to its original size. PP is also an excellent electrical insulator with low dielectric constant and dissipation factor. It has good moisture resistance, but not a very good oxygen barrier.
