HONY®POM CNC machined Delrin is an engineering plastic ideal for parts with high stiffness, low friction and low water absorption. It is widely used in the automotive and consumer electronics industries . Acetal or POM (Polyoxymethylene) is an engineering plastic known for being amongst the strongest and stiffest of all thermoplastics. There are two general types of Acetal resins available: Acetal Homopolymer and Acetal Copolymer. Acetal homopolymer resins are made by the DuPont Company under the trade name Delrin®. Homopolymers are typically used in highly regulated industries. HONY Plastic based China is professional Pom machined Parts Manufacturer High quality precision machined components - acetal milling & turning Specialising in intricate, tight tolerance work Extensive experience and high customer satisfaction Acetal Copolymer: Absorbs very little moisture High mechanical strength and rigidity Improved dimensional stability over comparable homopolymer formulations due to the lower level of crystallinity Low coefficient of friction Good compressive strength Good shock resistance Better chemical resistance with high pH solutions Lower centerline porosity than homopolymer in extruded shapes Excellent machinability Acetal Homopolyer: Stiffer Wide operating temperature range (-40°C to 120°C) Higher flexural modulus at room temperature Higher impact strengths at room temperatures and low temperatures Tensile strength is approximately 10-15% higher than comparable copolymers Slightly higher continuous use temperature than copolymer (95°C vs. 90°C) Good compressive strength Good shock resistance Lower thermal expansion rate Better wear resistance Easy to machine POM processing Components Typical Components & Applications: Electrical insulation Medical applications Food contact components (FDA compliant) Gears Bearings Housings Fasteners Bushings Handles Seals Valves Tooling Delrin fabrication part Industry Examples: Copolymer Food & packaging Medical & pharmaceutical Automative Electrical/Electronic Agriculture Homopolymers Typically used in highly regulated industries such as: Aerospace Nuclear Pharmaceutical Pom Delrin Acetal,Pom machined Parts,delrin fabrication part,POM processing Components,Acetal,Delrin,POM machining component Hony Engineering Plastics Limited , https://www.honyplastic.com
