  • PVC building trim
    Patent number: 5717019
    Abstract: The material is an extruded high impact, exterior PVC material comprising no more that 80 percent by weight of PVC resin and about 7 percent by weight of filler, said material being permanently bendable and has an average coefficient of thermal expansion of about 2.7.times.10 in/in/degree Fahrenheit over the range of ambient temperatures from minus 4 to plus 86 degrees Fahrenheit.A unique method of making the material extrudes it at lower temperatures than usually utilized. The material, formed in a strip is cooled to limited temperatures immediately before it is coiled.
