Products Description
POM Plastic Balls
Polyoxymethylene (POM), also known as acetal, is an engineering thermoplastic used in precision parts requiring high stiffness,
low friction, and excellent dimensional stability.
POM is characterized by its high strength, hardness and rigidity to −40 °C. POM is intrinsically opaque white, due to its high
crystalline composition, but it is available in all colors. POM has a density of 1.41g/cm3.
Typical applications for injection-molded POM include high-performance engineering components such as small gear wheels, eyeglass
frames, ball bearings, ski bindings, fasteners, guns, knife handles, and lock systems. The material is widely used in the
automotive and consumer electronics industry.

Heavy Plastic Ball FAQ
1. What is a POM plastic?
POM (polyoxymethylene), also known as acetal, is an engineering plastic that is often used in wet engineering environments. Known for its near-zero level of moisture absorption and excellent dimensional stability, acetal retains good mechanical performance even in applications requiring extensive machining, close ...
2. Is POM the same as Delrin?
POM plastic - Polyoxymethylene. POM material, also called acetal plastic, is a semi crystalline thermoplastic with high mechanical strength and rigidity. POM material has very good sliding properties, excellent wear resistance and low moisture absorption.
3.What does POM stand for in plastic?
POM (polyoxymethylene), also known as acetal or the branded name Delrin®, is a high-strength engineering thermoplastic valued for its dimensional stability, ease of machining, lubricity, and excellent wear resistance
4.Is POM plastic safe to use?
Polyoxymethylene can release toxic byproducts, such as formaldehyde gas, when it degrades or undergoes high-temperature processing. Formaldehyde exposure can cause respiratory irritation, allergic reactions, and other health concerns
5.Is POM harder than nylon?
When it comes to surface hardness, POM generally has a harder surface than nylon. The high degree of crystallinity in POM results in good surface wear properties and abrasion resistance. For nylon, additives are often used to improve surface hardness and wear resistance.
6.What are the disadvantages of POM plastic?
POM is prone to degradation when exposed to ultraviolet (UV) light for extended periods. This makes it less suitable for outdoor applications where prolonged sunlight exposure is expected. UV degradation can lead to discoloration, surface cracking, and a reduction in mechanical strength.
