EVA is the abbreviation of ethylene-vinyl acetate co-polymer, its material character is subjected to the contents of VA, and as such,its application is changed. Shoe sole foam is the main application. Heat-melt adhesive alsouses in agricultural warm-room film because of its soft property providing extended flexibility. EVA foam technique is of physic foam development or of chemical interlink making plastics substance, either by open cell or by closed cell, a foam material so as to reach the effects of light weight, cushion, sound absorption, shock absorption, heat insulation, filtering and packaging purposes. In addition to above points, this foam development with its decreasing gravity can reduce the cost; therefore, foam products are not only applying to household like shoe soles, water sports articles, cushion mats or building materials on air conditioning heat pipe, floor mat, stair mat but also using in industrial fields for packaging, heat insulation, anti-vibration, and filters according to demands.

Soft and extremely elastic yet tough
Competitive with rubber and vinyl in many electrical applications
Good clarity and gloss with little or no odor
EVA/PE foam department of SJ Group has more than 35 years experience with the following basic processes:

  • One time or two times open cell foams with respiratory, water absorptive, and filtering purposes.
  • One time or two times mould press foam with light weight, cushion, heat insulation, and packaging ends.
  • Chlorine free EVA one time or two times foams with its non-inflammable property applying to air conditioning heat pipe,sound insulation interior decoration, packaging and heat insulation materials.
  • General injection foam and direct injection foam are of light weight and cost effective whereas asymmetry extrusion foam is used on imitation wood (cut, slice, polish, saw, and nail are available.)
  • Continuous baking box foam is using on thin thickness EVA. Foam products are usually used as shoe sole, plastics floor and brick, and air conditioning heat pipe.
