ABSTRACT:
A windshield wiper blade capable of inexpensive manufacture and having good wipe quality comprises approximately 100 parts by weight of a vulcanizable elastomer including at least one silicone polymer, and about 75 to 220 parts by weight of a siliceous filler dispersed in the elastomer. The siliceous filler preferably includes a substantial portion of particles having a relatively large diameter in the range of 5 to 100 microns in order to lower the coefficient of friction of the wiper blade with respect to automotive windshield glass.
