China Good Radom Foam

Rigid, rigid and semi-rigid foam plastics in between. It has the ability to absorb impact load, excellent cushioning and shock absorption performance, sound insulation and sound absorption performance, and low thermal conductivity. Lightweight, heat-insulating, sound-absorbing, shock-proof and corrosion-resistant. Coected and non-floating. It is divided into closed-cell type and open-cell type. The above information about core foam plastics is introduced by the editor.; soft foam Plastics are mainly used as cushioning materials, foam artificial leather, etc. It is made of resin and has numerous micropores inside. There are numerous microporous plastics inside. It is made of resin as the m...

 Times or even dozens of times. After cooling and hardening, the pores inside can be fixed. Production process:Plasticizer (tire powder, ammonium bicarbonate) and reinforcing agent (talc powder or lithopone powder) are mixed evenly. 5.ufeffPMI foam'>Is the PMI foam insulation board good for heat insulation? In the plastic molding process, when some gas is added or some foaming agent is added, a large number of bubbles can be generated, which makes the volume of the plastic suddenly expand. Dissolving raw materials: dissolve waste foam, toothbrushes, combs, buttons and other materials Add the mixed organic solvent (acetone, toluene) to dissolve the PMI foam under agitation (ben...
