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。
 
Characteristics and Application 特点及用途
These products have good oil-resistant property, soft and flexible, and good processability. They can meet RoHS Standard. They are mainly used for the jacketing of oil-resistant and flame-retardant cables, elevator cables, oil-resistant soft wires of dust cleaner, heavy soft cables and crane cables.
产品具有良好的耐油性、弹性和柔软性,加工性能优异,符合RoHS环保标准。主要用于有耐油要求的电线电缆、电梯电缆、耐油吸尘器软线、重型软线、起重机电缆等护层材料。
 
Processing Indicator加工工艺
Recommend to use single-screw extruders with L/D= 20-25.
建议使用普通长径比为20-25的单螺杆挤出机进行生产。
