DuPont Low Warpage Polyoxymethylene Copolymer New Grade

So far, POM (polyoxymethylene) resin is mainly suitable for small parts and products, because large parts are very easy to warp, DuPont (DuPont) Company claimed to have solved this problem, the company's new brand Delrin930MF available Successfully used in some large parts and products, such as automatic instrument springs, shells, various kinds of coats and boxes, instruments and mechanical parts, various industrial products and daily necessities. The new brand trial product shows that complex shaped products that are difficult to form prior to processing have good surface flatness and high positioning accuracy and can be used to produce large products with minimal warping and complex shapes.
Delrin 930MF is an injection molding grade resin. Based on POM copolymer as the base resin and modified with inorganic filler, the molding shrinkage is 15% smaller than that of the unfilled brand, and the longitudinal and transverse shrinkage are nearly equal. Some basic properties such as dimensional stability, chemical resistance, low wear and abrasion resistance, creep resistance same as general POM, higher rigidity than non-filled POM, but low tensile strength and elongation at break, density 1.6g/cm3 , MFR 20g/10min, heat distortion temperature (1.84MPa) 101°C, flexural modulus 4165MPa, Izod notched impact strength 12.28J/m.
