POM Sheet: Exceptional Performance Leading New Industry Transformations
In the dynamic field of materials science today, POM Sheet (Polyoxymethylene Sheet) is gaining importance in many industries due to its unique and excellent properties.
Made from high - purity polyoxymethylene resin, POM Sheet uses advanced processing like extrusion and compression molding. In mechanical terms, it has very high tensile strength and flexural modulus. ASTM D638 and ASTM D790 tests show it outperforms similar plastics. Under high stress, it keeps good structure without much deformation. With a Shore hardness of 80 - 90HA, its high surface hardness and self - lubrication lead to low wear in the Akron test, making it great for high - precision, long - lasting wear - resistant parts.
Chemically, POM's regular molecular chain gives it strong stability. It resists a wide range of inorganic acids (e.g., sulfuric, hydrochloric), alkalis (like sodium hydroxide), and organic solvents (such as toluene, acetone). This makes it suitable for long - term use in chemical pipelines and electronic chip - making equipment.
POM Sheet's applications are growing. In automotive manufacturing, its low thermal expansion coefficient (7 - 11)×10⁻⁵/℃ helps make critical parts like fuel injection valve bodies and transmission gear rings, ensuring vehicle power systems work well under tough conditions.
In electronics and electrical appliances, with a volume resistivity of 10¹² - 10¹⁵Ω·cm and a dielectric constant of 2.8 - 3.2 (1MHz), it's an excellent insulator. Its low friction (0.2 - 0.3) reduces energy loss in gears, so it's used for device housings, connectors, and gears.
The industrial machinery industry uses it for ejector pins in injection molding and guide sliders in production lines. Its strength, wear - resistance, and self - lubrication cut maintenance and extend equipment life, fitting Industry 4.0 needs.
In medical devices, POM Sheet meets ISO 10993 biocompatibility. It stays stable during sterilization (ethylene oxide, moist heat), so it's used for parts like prosthetic joint linings and dental implants.
As demand for POM Sheet rises, manufacturers focus on R & D. They use advanced process control (sensor - based temperature and pressure control) for consistent product quality. They also modify the material with nano - fillers (carbon nanotubes, nano - silica) or blending (with polytetrafluoroethylene) to improve performance for different industries.
Yet, the POM Sheet market faces challenges. Fluctuations in formaldehyde prices, due to oil and coal price changes, make cost control hard. Intense global competition means companies must improve product quality, supply chain, and cost - effectiveness. However, with materials technology advancing and new industries emerging (new energy vehicles, high - end medical devices, intelligent equipment), POM Sheet has a bright future because of its potential and wide application possibilities.
In short, POM Sheet stands out in many industries with its great properties. It's likely to break through in more advanced areas, driving the materials industry forward.
