woodsac Posted June 25, 2003 Report Share Posted June 25, 2003 Thank you for your interest in our product. This material is a plastisol vinyl. When heated the vinyl melts into the liquid and when cooled becomes a rubbery soft material, the kind used for worms. Call us at 800-533-5843 if you have any other questions.Delvie's Plastics inc. This is the reply email I received from Delvie's Plastics. I ran across them on the net. I basically just asked for a little more info on their products (web site is very uninformative). Since I pour so few plastics, I won't be pursuing this. But if anyone else is interested, let us know what you find out. Quote Link to comment Share on other sites More sharing options...
