IMPROVED PVC BUILDING TRIM |
摘要 |
The material is an extruded high impact, exterior PVC material comprising no more than 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.
