Abstract:
A melt-blended slip-coating for a weatherseal comprising,(i) an olefin-based thermoplastic vulcanizate (TPV) having a hardness in the range from about 85 Shore A to about 45 Shore D; (ii) a reaction product (mPP-g-TPU) of (a) a graft copolymer of an unsaturated monomer bearing an acid anhydride group and polypropylene, melt-blended with (b) a thermoplastic polyurethane (TPU); and, (iii) a random copolymer of two or more &agr;-olefins having from 2 to 12 carbon atoms; said slip-coating having a hardness lower than Shore D 50, a Taber abrasion resistance (measured by ASTM D1044-94 at 500 cycles) lower than 50, and coefficients of friction, both static and dynamic, lower than about 0.4.
