HDPE injection molding processing condition

The properties of HDPE are controlled by the density, and molecular weight distributions. Injection molding grades typically have a narrow molecular weight distribution. When the density is 0.91 - 0.925 g/cm^3, the material is known as Type 1; Type 2 materials have densities in the range of 0.926 - 0.94 g/cm^3, and Type 3 materials have densities in the range of 0.94 - 0.965 g/cm^3.
