Low pressure injection moldable compositions |
摘要 |
This invention relates to injection moldable type elastomeric compositions having a viscosity at 200 DEG C. at 0.73 sec-1 of less than about 8x104 poises. The compositions used for elastomeric articles include 100 parts of a neutralized sulfonated EPDM terpolymer; about 25 to about 150 parts per hundred of a non-polar process oil; about 25 to about 200 parts per hundred of a filler; 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 least than about 100 parts per hundred by weight.
