Product Description產品描述
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.
環保型90℃聚氯乙烯耐油阻燃柔軟護套料是以優質聚氯乙烯樹脂為基料，加入特種增塑劑、特種穩定劑、高效阻燃劑等助劑，經混合、塑化、造粒而成的粒狀電纜料。
