What are high quality nylon plastic pom rods?
POM rod is the abbreviation for polyoxymethylene rod, which is a thermoplastic crystalline polymer.
Advantages of high quality nylon plastic pom rods
High strength and rigidity. POM rods have high hardness, strength, and rigidity, and can withstand significant tensile, bending, and compressive stresses.
Easy to process. POM rods have a low density and are easy to cut, grind, mill, and shape, providing a wide range of choices for different processing techniques.
Limitations of high quality nylon plastic pom rods
Chemical stability. Not resistant to strong acids and bases, prone to chemical reactions when in contact with these substances, resulting in performance degradation, structural damage, and other issues.
Impact toughness. POM rods have relatively low impact toughness and are prone to damage such as cracking and fracture when subjected to large impact forces.
The main function of high quality nylon plastic pom rods
POM rods mainly have functions such as mechanical support, wear resistance, self-lubricating, insulation, and chemical protection. They can be used to manufacture structural components, transmission parts, insulation materials, etc. and play an important role in multiple fields.
The working principle of high quality nylon plastic pom rods
Relying on molecular structure to achieve mechanical support, high hardness and tight arrangement to reduce wear, molecular chain characteristics to provide self-lubricating, covalent electronic structure to achieve insulation, and chemical stability and surface protection to provide chemical protection.
There are various types of high quality nylon plastic pom rods , how to choose the one that suits you
一、Consider the usage environment
1.Temperature conditions. If the POM rod needs to be used in a low-temperature environment, such as around -40 ℃, ordinary POM rods such as POM-C/H can meet the requirements; If the temperature is high, close to 100 ℃ or even higher, POM-H rod can be selected, which has a higher heat resistance coefficient and can maintain good mechanical properties between -40 ℃ and+110 ℃.
2.Chemical environment. In terms of chemical corrosion resistance, POM-C copolymer has better performance than POM-H copolymer in terms of resistance to strong alkali, hydrolysis, and thermal oxidation degradation. If there is frequent exposure to strong alkali and other chemicals in the work environment, POM-C is a better choice; If there are fewer chemical substances in contact, the high crystallinity and mechanical strength of POM-H are more advantageous.
二、According to mechanical performance requirements
1.High rigidity and hardness requirements. If the rigidity and hardness requirements of POM rods are extremely high, such as for manufacturing mechanical structural components, gears, etc. that require high pressure, POM-H homopolymer is a better choice. Its high crystallinity can provide excellent rigidity, hardness, and mechanical strength.
2.Wear resistance and self-lubricating requirements. POM rods themselves have good wear resistance and self-lubricating properties, but the combination of POM-H+PTFE is even better. After adding PTFE fibers, their lubrication is better, which can effectively reduce the friction coefficient and wear, especially suitable for manufacturing components such as bearings and shaft sleeves that require good wear resistance and self-lubricating properties.
三、According to the processing method and cost
1.Processing method. If machining is carried out through an automatic lathe, ordinary POM rods (such as POM-C/H) are very suitable because they have good machinability; If special processing techniques are required or high dimensional accuracy is required, it may be necessary to choose POM rods with higher quality and more stable performance, such as imported POM rods or products from specific brands.
2.Cost factor. Generally speaking, the cost of POM-C is relatively low, while the cost of POM-H and POM rods with added special fibers will be higher. On the premise of meeting the usage requirements, the appropriate POM rod should be selected according to the budget. If cost control is strict and the performance requirements of the usage environment are not extremely demanding, POM-C is a more economical choice.
四、Refer to the application field and specific purpose
1.In the field of electronics. In the electronics industry, such as manufacturing fixtures for silicon chip processing, hard disk drives, and printed circuit boards, anti-static POM rods, namely ESD225, are required to prevent discharge problems from parts in contact with people and avoid damage to electronic components.
2.Food contact field. If POM rods are used in food processing equipment or components that come into contact with food, it is necessary to choose POM rods that meet food hygiene standards and have physiological inertness. For example, POM-H rods have good physiological inertness and are suitable for contact with food.
