Inquiry (采购产品): polyethylene We are having trouble with a new part that we are having rotationally molded for us. It is shrinking more than they expected. We are using low density polyethylene. Is the another option using polyethylene or a combination of materials that will hold up in septic enviroment and that will shrink less. Cost is also a small factor. **** Hidden Message ***** James Zimmerman 3649 Cane Run Rd Louisville, KY 40211-1961 USA Company: Zoeller Pump Co.
