Pom Sheet Overview: Features And Applications
5 week ago
Product Composition
The main component of POM sheets and POM rods is polyoxymethylene (POM), also known as "Delrin." POM is a crystalline plastic with a high-density, non-side-chain, and highly crystalline linear polymer structure, which gives it excellent comprehensive properties.
Performance Characteristics
Physical Properties: POM sheets and POM rods have a smooth and glossy surface, appearing hard and dense. They are generally white or yellowish, with high crystallinity, good colorability, and excellent dimensional stability, along with minimal water absorption.
Mechanical Properties: POM sheets and POM rods exhibit high hardness and rigidity, excellent wear resistance, self-lubricating properties, and creep resistance. This allows them to withstand high loads and repeated impacts without deformation.
Thermal Properties: POM sheets and POM rods have a high heat distortion temperature and can be used continuously within a temperature range of -40°C to 104°C.
Electrical Properties: POM sheets and POM rods maintain stable dielectric loss and dielectric constant within a wide frequency and temperature range, along with good arc resistance.
Chemical Properties: POM sheets and POM rods exhibit good resistance to solvents, oils, weak acids, and weak bases.
Advantages
High mechanical strength, rigidity, and hardness, along with excellent elasticity, sliding properties, and wear resistance.
Good creep resistance, even at low temperatures, and high impact strength.
Excellent dimensional stability and mechanical properties.
Physiologically inert, suitable for contact with food.
Good electrical properties and environmental resistance, as well as solvent resistance.
Good resilience.
Application Fields
POM sheets and POM rods have extensive applications in the automotive, electronics, machinery, and medical industries. Specifically:
Automotive Industry: POM material is widely used in automobile manufacturing, mainly for interior parts, transmission systems, fuel systems, and seat adjustment mechanisms. Its excellent wear resistance and corrosion resistance make it an ideal choice for automotive components.
Electronics: POM material finds extensive applications in the electronics industry, such as electrical switches, sockets, insulators, and electronic connectors. Its good electrical and mechanical properties meet the requirements of electronic products for material performance.
Mechanical Engineering: POM material is widely used in the mechanical field for manufacturing gears, bearings, sliding bushings, and transmission chains. Its low friction coefficient and self-lubricating properties reduce energy loss and friction wear in mechanical devices.
Medical Equipment: POM material is extensively used in the manufacture of medical equipment, such as surgical instruments, syringes, infusion sets, and artificial joints. Its chemical stability and biocompatibility make it one of the commonly used materials in the medical field.
