Polyethylene is a class of thermoplastics practically ubiquitous in consumer products. In its foam form, polyethylene is used in packaging, vibration dampening and insulation, as a barrier or buoyancy component, or as material for cushioning. It is most frequently seen as a packaging material.
The non-cross polyethylene foam is developed by thermo chemical expansion with low - density polyethylene resigns. It not only has excellent characteristics of thermal insulation, elasticity and shock-absorption but also has a very strong chemical resistance besides being water / weather proof.
