Feature :
Delrin (Polyoxy-Methylene), also known as Acetal, Polyacetal, and POM, is an engineering thermoplastic commonly used for precision
parts that require high strength, hardness and rigidity. It is a tough material with a low coefficient of friction and high
abrasion resistance. It has good electrical and dielectric properties, low water absorption. Naturally white in color it does
accept opaque colors well and can be polished to a shine. Delrin is typically difficult to bond but can be bonded with epoxies,
polyurethanes and cyanoacrylates (superglue). It has good chemical resistance but is sensitive to mineral acids, chlorine, and
alkaline degradation.

About US
With more than 25 years experience, Kaifeng Bell is a professional solid plastic ball manufacturer in China. Material : Acetal (POM), Polypropylene (PP) ,Nylon (PA PA66) ,PTFE(Teflon) ,PS ,PEEK, Acrylic (PMMA) , etc. Size from 0.8mm to 100mm. Grade G0 G1 G2
We have two factories to produce our balls , one is Located in Henan province (cover 10000 square meters and with more than 200 sets machines), another is located in Shandong province (cover 5000 square meters and with more than 50 sets machines) As plastic ball supply ,we also produce (304 316 316L 440C 420C) stainless steel ball, brass copper ball,(soda-lime&borosilicate) glass ball,Ceramic ball ,Tungsten Carbide Ball, sattelite steel ball,Aluminum Balls . Sizefrom 0.3mm to 100mm Grade from G5 to G1000
Quality Assurance
Our technical engineer has over 30 years experience . After finished to produce balls, we will take sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer.
Delrin Bearing 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.
