Density Tester

Density tester is the device that meassures the density of the HDPE material by in accordance with the ASTM D 1505.

Melt Flow Rate Test Machine

The melt flow rate is a one number indication of the viscosity of a HDPE in the melt phase. It is defined as the mass of polymer in grams flowing per 10 minutes through a capillary of specific diameter and length by pressure applied via a range of standard weight at specified temperature. The melt flow rate test is accordance with ASTM D 1238
