The hardness of polyethylene sheet depends on its type and purpose.
Polyethylene sheet can be divided into two main types: high-density polyethylene (HDPE) and low-density polyethylene (LDPE). HDPE has higher hardness, higher rigidity, hardness and strength, while LDPE has better softness, elongation and impact strength. In addition, the hardness range of polyethylene sheet is approximately between 20-90, and the specific hardness depends on its composition and processing method.
The impact of hardness on application
High hardness (such as high-density polyethylene): Suitable for applications requiring higher strength and rigidity, such as building structural materials, piping systems, etc.
Low hardness (such as low-density polyethylene): Suitable for applications requiring good flexibility and impact strength, such as automotive interiors, wire and cable insulation layers, etc.
Physical properties of polyethylene sheet
Polyethylene sheet has the following physical properties:
Impact resistance: It has good impact resistance and is suitable for various impact load environments.
Low temperature resistance: It can still maintain good physical properties at low temperatures.
Corrosion resistance: Good corrosion resistance to most chemicals.
Aging resistance: Can maintain a long service life in outdoor environments.
Processing performance: Easy to cut, bend and weld, convenient for processing and installation.
