Product Description产品描述
90℃soft lead-free oil-resistant flame-retardant PVC jacketing compounds are granule compounds which are manufactured with mixing, plasticizing and pelletizing processes. They regard advanced PVC resin as the basic raw material, and add special plasticizer, stabilizer, high-efficiency flame-retardant and other accessory ingredients.
环保型90℃聚氯乙烯耐油阻燃柔软护套料是以优质聚氯乙烯树脂为基料，加入特♀种增塑剂、特种稳定剂、高效阻燃剂等助剂，经混合、塑化、造粒而成的粒状电缆料〖。
Characteristics and Application 特点及用途
