Shanghai Metal Corporation is a leading manufacturer and supplier of POM (Paraformaldehyde Copolymer & Homopolymer) sheets. POM is a thermoplastic engineering plastics with high melting point and high crystallinity, a yellowish or white crystalline polymer with smooth and dense surface. According to the chemical structure of molecular chain, it can be divided into polyformaldehyde copolymer and polyformaldehyde homopolymer.
Shanghai Metal Corporation has a complete quality control system. Our POM sheets are made of CELANESE brand raw material, have excellent mechanical properties, after full annealing, the stress relieving is eliminated and the dimensional stability is high. In order to ensure zero defect and zero complaints, we monitor and control every link from raw materials to production, to the warehousing and shipment of finished products. The inspection includes the appearance data of the product, including the length, width, thickness, weight, flatness, hardness, surface and cross section. In addition, according to customer requirements and application conditions, we have well-equipped facilities to test the physical and chemical properties of the products, such as the impact strength, aging resistance, flame retardancy, etc.
If you want to know more about our products or POM sheet price, please feel free to contact us. We will reply you within 24 hours.
