EPDM 3722P 美国陶氏 三元乙丙橡胶 应用塑料改性
- EPDM/3722
- NDR 3722P is a semicrystalline, very low diene containing polymer with low viscosity for good processability. The low unsaturation provides excellent long term thermal and UV stability. It is specially designed for medium voltage wire and cable applications. It can also be used in peroxide cured molded and other extruded applications. NDR 3722P is developmental and made via INSITE™ technology.
