PolyPLASTY PolyPET PET
Categories:	Polymer; Thermoplastic; Polyester, TP; Polyethylene Terephthalate (PET); Polyethylene Terephthalate (PET), Unreinforced
Material Notes:	Great mechanical strength, excellent dimensional stability (better than POM), abrasion resistance and very good shear properties. Good electrical properties; it is physiologically acceptable and flame retardant. It has very low water absorption, which does not affect its mechanical and electrical properties. Its very low thermal expansion coefficient puts it among the leading thermoplastics. This material is easily glued and welded. Information provided by PolyPLASTY.
