Claims19
A thermoplastic composite masterbatch comprising a fiber phase and a polymer phase:
- (a) the fiber phase comprising greater than 50 wt. % a glass fiber with a length greater than about 1 mm, a diameter greater than about 0.8 microns and an aspect ratio greater than about 10, the fiber having about 0.1 to 5 wt. % of an exterior coating comprising a mixture of organo metallic interfacial modifiers, the wt. % based on the fiber phase and;
- (b) the polymer phase comprising a thermoplastic polymer comprising vinyl chloride and a chlorinated polyethylene (CPE) at a weight ratio of about 0.1 to 10 parts by weight of polymer per part of CPE;
- wherein the master batch and a composite there\from has a COTE (D6341) of 0.5 to 1.5 in/in/° F., a room temperature impact resistance of about 200 to 1000 ft-lb-in−1 (ASTM D256), a flexural modulus (ASTM D790) of about 0.4 to 3 Mpsi and a heat distortion of less than about 50 hrs. at 143° F.
A thermoplastic composite member comprising a fiber phase and a polymer phase:
- (a) the fiber phase comprising about 1 to 20 wt. % of a glass fiber with a length greater than about 1 mm, a diameter greater than about 0.8 microns and an aspect ratio greater than about 10, the fiber having about 0.1 to 5 wt. % of an exterior coating comprising a mixture of organo metallic interfacial modifiers, the wt. % based on the fiber phase;
- and;
- (b) the polymer phase comprising 80 to 99 wt. % of a thermoplastic polymer comprising vinyl chloride and a chlorinated polyethylene (CPE) at a weight ratio of about 0.1 to 50 parts by weight of CPE per 100 part of polymer;
- wherein the composite has a COTE (D6341) of 1.0 to 3.0×10−5 in/in/° F., a room temperature impact resistance of about 100 to 500 ft-lb-in−1 (ASTM D256), a flexural modulus (ASTM D790) of about 0.4-0.5 Mpsi and a heat distortion of more than 50 hours at 143° F.
