Hdpe against radiator melt
Webpressure. Melt flow rate is inversely proportional to viscosity of the melt at the conditions of the test; through it should be borne in mind that the viscosity for any such material depends on the applied force. Melt flow rate is very commonly used for polyolefin, polyethylene being measured at 〖190〗^o C and WebHDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m 3. The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 …
