    • Open-cell foam of ethylene-propylene-diene rubber that can convert to open-cell foams at the foaming of EPDM, rather than after the foaming of the same, and can produce low impact resiliency and improved filling capability. After 0.1-40 parts by weight of organic foaming agent, 2-40 parts by weight of inorganic foaming agent, and 2-40 parts by weight of foam auxiliary agent per 100 parts by weight of ethylene-propylene-diene rubber are mixed, the mixture is vulcanized and foamed to thereby produce open-cell foam of ethylene-propylene-diene rubber. This open-cell foam of ethylene-propylene-diene rubber has low impact resilience and good sealing performance so that it can be used as sealing materials of a variety of industrial products.
    • 乙烯 - 丙烯 - 二烯橡胶的开孔泡沫,可以在EPDM发泡时转化为开孔泡沫,而不是在其发泡之后,可以产生低冲击弹性和改善填充能力。 将0.1-40重量份有机发泡剂,2-40重量份无机发泡剂和2-40重量份泡沫助剂相对于每100重量份乙烯 - 丙烯 - 二烯橡胶混合, 将混合物硫化并发泡,从而产生乙烯 - 丙烯 - 二烯橡胶的开孔泡沫。 这种乙烯 - 丙烯 - 二烯橡胶的开孔泡沫体具有较低的冲击弹性和良好的密封性能,因此可用作各种工业产品的密封材料。
