Abstract
Styrene Acrylonitrile (SAN) copolymer has styrene with high expanded durability and finds some useful applications. Applications involving replacement of metal by plastics due to light-weight, high quality and firmness attributes were seen. But they are limited as they cannot withstand higher temperature applications. PTFE that finds a perfect filler material has high temperature ability, self-greasing up, high chemical inertness, low friction, corrosion resistance, low outgassing properties. Injection molding process helped addition of copolymers of SAN and ABS to 10% PTFE by weight, 20% PTFE by weight blends and composite samples were prepared successfully using the melt condition. Experimental results show PTFE filler added composites exhibiting improved thermal conductivities and coefficient of linear thermal expansion.
