Abstract

The invention relates to a foam plastic, concretely relates a soft polyethylene foamed plastic, and belongs to the technical field of foamed plastics. The soft polyethylene foamed plastic comprises, by weight, 40-90 parts of low-density polyethylene resin, 2-14 parts of stannous octoate, 3-9 parts of dichloromethane, 1-8 parts of benzoyl peroxide, 10-16 parts of trimethylolpropane trimethacrylate,8-14 parts of acrylonitrile, 1-6 parts of an organic peroxide cross-linking agent, 2-7 parts of polysulfone resin, 3-9 parts of pentaerythritol, 2-10 parts of a plant powder filler and 4-10 parts ofisopentane. The plastic product has the advantages of suitable softness, light weight, high resilience, and good flame retardation property; and the foamed plastic has a light color, so the productionof color products through adding pigments is facilitated.
