Webthe melt. The residence time of the melt in the die also will determine how much degradation will occur. The average time in the die is the ratio of the weight of molten polymer held in the die to the output rate. For example, a 15 inch (380 mm) pipe die holds about 200 lb (91 kg) of molten unplasticized polyvinyl chloride (UPVC). WebBusiness profile of Rays Extrusion Dies Tubing Co, located at P.O.
