Product Description产品描述
Lead-free elastomeric PVC/NBR jacketing compounds are granule compounds which are manufactured with mixing, plasticizing and pelletizing processes. They regard advanced PVC resin and nitrile-butadiene rubber as the basic raw material, and add special plasticizer, stabilizer, flame retardant and other accessory ingredients.
环保型聚氯乙烯/丁腈复合物弹性体护套料是以优质聚氯乙烯树脂和丁腈橡胶为基料，加入特种增塑剂、稳定剂、阻燃剂等助剂，经混合、塑化、造粒而成的粒状电缆料。
