Cấu trúc sản phẩm
Polyoxymethylene (POM), also known as polyacetal or acetal, is a high-density, high-crystallinity thermoplastic engineering plastic, commonly referred to as Delrin or engineering plastic steel. It is polymerized from formaldehyde and mainly divided into POM homopolymer (POM-H) and POM copolymer (POM-K). This material is widely used in various engineering applications due to its excellent physical, mechanical, and chemical properties, especially its friction resistance.
POM materials have high-density crystallinity without side chains, exhibiting superior comprehensive performance. It is a smooth, glossy, hard, and dense material, typically pale yellow or white, capable of long-term use in the temperature range of -40°C to 100°C. POM's wear resistance and self-lubrication surpass most engineering plastics, and it also has good oil and peroxide resistance. By adding UV agents, its UV resistance can be significantly improved.
POM FW-715C is a specific grade of POM, natural in color and granular, suitable for injection molding. Its tensile strength at 23°C is 54 MPa, with a static friction coefficient of 0.09 and a dynamic friction coefficient of 0.11. POM FW-715C has an elongation of 35%, with high flexural modulus and flexural strength of 2900 MPa and 78 MPa, respectively. Regarding thermal deformation temperature, it is 160°C at 0.45 MPa and 125°C at 1.8 MPa in an unannealed state.
Additionally, POM FW-715C has low Taber wear and good cantilever beam notched impact performance, with values of 10 mg/1000 cycles and 6.12 kJ/m² at room temperature, respectively. Its specific gravity is 1.48 g/cm³, with a shrinkage rate of 1.7% in the flow direction and 2% in the vertical direction. The material has a Rockwell hardness of 70 and a fire rating of UL94 HB for thicknesses ranging from 0.95 to 2.9 mm, suitable for black, white, and red materials.
