POM (Polyoxymethylene) rigid pipe is a high-performance engineering plastic pipe made of highly crystalline linear polymers with excellent mechanical strength, rigidity, wear resistance and dimensional stability. POM is divided into homopolymer POM and copolymer POM, both of which show excellent fatigue resistance, low friction coefficient and good chemical stability, and are widely used in precision machinery, automobiles, electronics, medical and fluid delivery systems.
POM tubes are ideal for high-end industrial applications due to their high strength, wear resistance, low friction and excellent dimensional stability. They are widely used in the automotive, machinery, electronics, medical and other fields, demonstrating their excellent value as high-performance engineering plastics, especially for key components that require precision processing, long-term durability and stable performance.
Performance characteristics:
High mechanical strength and rigidity: tensile strength can reach 60~70 MPa, high bending modulus, suitable for high-load structural parts.
Excellent wear resistance and low friction coefficient: low friction coefficient (0.1~0.3), good self-lubrication, suitable for sliding parts.
Excellent dimensional stability: low moisture absorption (<0.25%), can still maintain dimensional accuracy in humid or temperature-changing environments.
Chemical and solvent resistance: good tolerance to most organic solvents, greases, weak acids and weak alkalis, but not resistant to strong acids and strong oxidants.
Fatigue resistance and creep resistance: long-term dynamic load is not easy to deform, suitable for repeatedly moving parts.
Good electrical insulation: high dielectric strength, suitable for electronic insulation parts.
Temperature application range: -40℃ ~ +100℃ (can withstand 120℃ for a short time).
Advantages of pom tube
Replacing metal and ordinary plastics: Compared with metal, POM pipes are lighter, more corrosion-resistant and noiseless; compared with ordinary plastics (such as PVC, PP), they have better mechanical strength, wear resistance and dimensional stability.
Excellent processing performance: easy to turn, drill, mill, weld (hot plate welding, ultrasonic welding), and can be processed into high-precision parts.
Low hygroscopicity: It can still maintain stable performance in a humid environment and avoid dimensional changes caused by water absorption.
Economical and long life: wear-resistant and fatigue-resistant, reducing maintenance and replacement frequency, and reducing comprehensive use costs.
