HDPE
Polyethylene
High density polyethylene, also known as HDPE, odorless, non-toxic, feel like wax, good chemical stability, can resist most of the acid, alkali, organic solutions and hot water erosion. Good electrical insulation, easy to weld, through the food FDA test, can be used as food grade parts, the use of temperature 70°C~90°C.
Advantage
Characteristic：
Low density, good toughness (also suitable for low temperature conditions), good tensile property, good electrical and dielectric insulation, low water absorption, low water vapor permeability, good chemical stability, wear resistance.
