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。

Above data is just for your reference and need to be adjusted according to the actual situation.
以上加工条件只是参考，具体需根据实际情况做适当调整。
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。
