Polyethylene chemical cross-link agent is high expansion foam with self-extinguishing property on semi  
  hard polyethylene foam sheet with closed-cell structure, expanding at 40 times with polyethylene  
  cross-link agent. It has good heat insulation, anti shocking ability, weather profanes, chemical  
  resistance, light weight and process ability.
  It is widely used for electric & automobile components, construction and engineering works, industrial  
  heat insulation, packing, buffering, sports, and leisure tools and sundry goods.
  Polyethylene non-crosslink agent, semihard polyethylene foam, is polyethylene expansion foam under 
  closed-cell structure with 15~40 times expansion ratio. It is good for cushioning, buffering, heat 
  resistance, water proofeness, chemical properties and process ability as well as cheapness.
  So it is widely used for construction, engineering works, packing, anti-shocking material, sports,
  leisure and sundry goods and laminating product.  Polyethylene is closed-cell foam. It has an excellent heat insulation, light weight, medical resistance  
  and buoyancy.
  It is widely used in various fields like sundry goods, interior finish of autocar, cushion, and 
  anti-shocking material and electric parts.
