Product Description 产品描述
EP-3000 series are dynamic vulcanized compound by EPDM and PP. It is also called thermoplastic TPV. They has various excellent properties such as good climate-resistant (UV, ozone, sunshine, rain), anti-aging, anti-moisture, chemical resistant (acid, alkali, alcohol, ether) and electrical property. Their cold-resistant property is very well and can be worked in -40℃~125℃for long time. EP-3002 and EP-3003 are medium level oil-resistant. The hardness of the series can reach 75A-40D.
EP-3000是三元乙丙胶与聚丙烯(EPDM/PP)的动态硫化共混物,又称热塑性硫化橡胶(TPV),具有硫化橡胶的各种优异性能,有卓越的耐侯性(紫外线,臭氧,日光,雨水)耐老化,耐水性,耐化学品(酸、碱、醇、醚)和电性能。耐低温性能卓越,能在-40℃~125℃的温度中长期工作。其中3002和3003有中等耐油性。硬度范围可以做到:75A-40D。

Dry Condition 干燥条件
No need for drying in normal environment. If the compound was affected with damp, dry it under 90℃conditions for 2-3 hours or under 70-80℃conditions for 3-4 hours. Keep the moisture content smaller than 0.1wt%.
一般不需干燥。如受潮,在90℃条件下干燥2-3小时,或在70-80℃条件下干燥3-4小时,保持树脂含水量小于0.1wt%后再使用。
