Product details

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.

FAQ

1.Q: What are the main characteristics of POM rods?

A:POM rods feature high mechanical strength, great rigidity, high hardness, as well as excellent wear resistance, self-lubrication and dimensional stability. Compared with nylon (PA), POM has lower water absorption and more stable dimensions, making it suitable for the manufacturing of precision parts.

2. Q:Which is more wear-resistant, POM rods or nylon rods?

A:The wear resistance and self-lubrication of POM rods are superior to those of nylon. Especially in dry environments, the low coefficient of friction of POM makes it more suitable for sliding parts such as gears and bearings, while nylon is prone to deformation after absorbing moisture, which affects its wear resistance.

3.Q: Can POM rods withstand high temperatures?

A:Yes, POM rods can operate stably for a long time from -40°C to 100°C, and can withstand short-term temperatures up to 120°C. The heat distortion temperature of homopolymer oxymethylene (POM-H) is higher (about 175°C), which is superior to that of copolymer oxymethylene (POM-C) and nylon.

4.Q: Are POM rods resistant to acids and alkalis?

A:POM is resistant to weak acids, weak bases and organic solvents, but strong acids (such as concentrated sulfuric acid) or strong bases can corrode its surface. In contrast, PTFE (polytetrafluoroethylene) has better corrosion resistance, but its mechanical strength is far lower than that of POM.

5.Q: Why is the dimensional stability of POM rods better?

A:The water absorption rate of POM is extremely low (< 0.25%), and it hardly deforms in a humid environment. The water absorption rate of nylon is as high as 8%, which can easily lead to dimensional deviations and requires secondary processing and adjustment.

6. Q:What are the core application fields of POM rods?

A:It is mainly used in precision engineering: automotive transmission parts, electronic gears, medical instrument parts, etc. Compared with nylon, the rigidity and stability of POM are more suitable for high-load scenarios. Compared with metals, its lightweight and self-lubricating property can reduce maintenance costs.
