1 part of benzothiazole sulfonamide of agent N- cyclohexyl -2-, 0.5 part of dibenzothiazyl disulfide, tetramethylthiuram disulfide
0.5 part, 5 parts of microballoon foaming agent.
Plasticizer mass fraction is lower in the formula, foamed material can not fully wrapped around microballoon foaming agent, to make its pressure
Contracting resilience performance reduces.
Embodiment 2:
