Blend compositions |
摘要 |
This invention relates to injection moldable and extrusion type elastomeric compositions having a viscosity at 200 DEG C. at 0.73 sec-1 of less than about 8x105 poises. The compositions used for elastomeric articles include 100 parts of a neutralized sulfonated EPDM terpolymer; less than about 200 parts per hundred of a paraffinic, low polarity process oil; about 25 to about 200 parts per hundred of an amorphous silica filler treated or untreated; and a preferential plasticizer at about less than 50 parts per hundred based on 100 parts of the sulfonated elastomeric polymer. The composition may also include a crystalline polyolefinic thermoplastic at less than about 100 parts per hundred by weight per 100 parts of sulfonated polymer.
