DCP داراي مقادير مختلف EPDM مطالعه اثر زمانمندي در روغن ترمز بر خواص فيزيكي - مكانيكي و مقاومت گرمايي آميزه هاي لاسيتيك

The effect of poly (ether glycol) brake fluid on an EPDM elastomer based on cthylidine norbornene (ENB) has been studied. Different amounts of proxidc curing agent (DCP) were used and the effect of aging of brake fluid (at 100°C for 70 h) on technical properties of EPDM compound has been studied. By increasing the amount of DCP not a very significant change has been observed. Tensile strength and modulus increased but elongation-at-brcakc and abrasion loss have decreased due to oxidative degradation and cross-linking. Hardness has remained unchanged due to the replacement of plastici/er with brake oil.
