三元乙丙橡胶是乙烯、丙烯以及非共轭二烯烃的三元共聚物,1963年开始商业化生产。每年全世界的消费量是80万吨。EPDM主要的特性就是其优越的耐氧化、抗臭氧和抗侵蚀的能力。由于三元乙丙橡胶属于聚烯烃家族,它具有极好的硫化特性。在所有橡胶当中,EPDM具有低的比重。它能吸收大量的填料和油而影响特性不大。因此可以制作成...

The impact strength of the blends was measured in three fracture directions, namely, along the shear flow direction, perpendicular to and oblique (45 deg) with the flow direction. A definite B-D transition of impact strength was found at 20 wt% of EPDm content along the shear flow direction...
rubber in comprehensive performance. The disadvantage is that oxygen and ozone resistance is poor, easy aging, metamorphism, oil and solvent resistance is not good, the first corrosion resistance of acid and base is low, heat resistance is not high. Temperature range: about 60 DEG C ~80. ...

plasticizing section is 55 to 80 DEG C, the extrusion temperature of a feeding section is 55 to 60 DEG C, and the extrusion temperature of a screw section is 40 to 60 DEG C; and conditions of vulcanization are as follows: a temperature is 180+/-5 DEG C and time is 40 +/-5 min...
Electrical characteristics: dielectric constant, dielectric loss and volume resistivity were measured and correlated with structural changes induced by heating in water at three temperatures (40/spl deg/, 60/spl deg/ and 80/spl deg/C). IR and electrical determinations prove that oxygenated products ...
The insulating rubber disclosed by the invention simultaneously uses LDPE and EPDM by adopting a rubber and plastic combined use method and mainly enhances the tensile strength of the insulating rubber and the volume resistivity of the insulating rubber at 20 DEG C.田维生...
