Whats the melting point of MDPE?



Answer:
Roughly 120-130 Celsius, depending on the grade.

Light density melts around 15 Celsius below this, high density around 15 Celsius above. (120 Celsius = 250 Fahrenheit)

Grades are measured in g/cc (grammes per cubic centimetre) and range from Very Low Density Polyethylene (VLDPE, 0.880g/cc) through to High Density Polyethylene (HDPE, 0.941g/cc and above.)

There are also grades based on molecular weight, but that's just being pedantic..!
105-115 C, depending on density ( MDPE's of 0.926-0.940/g/cc ) and manufacturer and formula.
