POM Resin (Polyformaldehyde Resin)

Q: Can POM resin be used for food-contact applications?

Yes, but only FDA-approved food-grade POM should be used. It’s commonly used in food processing equipment, beverage dispensers, and kitchen appliances. We offer FDA-compliant POM resins , so feel free to contact us for specific grades.

Q: What colors are available for injection molding?

Standard natural white/black, plus 15 RAL colors in stock. Custom color matching with 3kg MOQ. Color samples can be shipped within 48hrs.

Q: Is POM suitable for automotive fuel system parts?

Yes, POM-C copolymer variants are widely used in automotive applications, including fuel system components, door locks, and seatbelt mechanisms due to their good chemical resistance and dimensional stability. *Key Certifications: * ✅ UL94 HB (Flame Resistance) ✅ IMDS (Automotive Material Data Submission) ✅ RoHS & REACH Compliance If you need POM resin specialized for automotive use, let us know your specifications!

Q: Does POM work well in high-wear industrial applications?

Yes, POM is excellent for industrial machinery parts such as gears, bushings, rollers, bearings, and conveyor system components. Its low friction and self-lubricating properties extend the lifespan of moving parts. Need custom formulations with reinforced additives? Talk to our engineers for glass-fiber and PTFE-reinforced POM grades!

Q: What is the minimum order quantity (MOQ)? Can I place a small trial order?

Standard grades require a 1-ton minimum order for cost-effective transport. However, for new customers, we offer: ✅ 50kg free trial samples (shipping included) ✅ Technical support at no extra cost ✅ 24-hour logistics tracking

Q: Can I get a modified POM resin grade for my application?

Yes! We offer custom-modified POM resin grades, including: 🔹 Glass fiber-reinforced POM → Higher stiffness & wear resistance 🔹 PTFE-filled POM → Lower friction & improved sliding behavior 🔹 Flame-retardant POM → Compliant with UL94 V-0 for electrical components 🔹 ESD/Anti-static POM → Suitable for electronics manufacturing Our R&D team can develop a custom grade tailored to your needs—just send us your technical requirements!

Q: How do I prevent warping or shrinkage when molding POM resin?

Warping or shrinkage in injection molding is common due to POM’s crystalline nature. Here’s how to avoid it: ✅ Optimize mold temperature → Maintain 90-120°C for even cooling ✅ Reduce residual stress → Use gradual cooling cycles ✅ Choose low-shrinkage POM grades → We offer low-warpage modified POM If you’re having molding issues, our technical team provides real-time troubleshooting support!

Q: Do you offer long-term supply partnerships? What are the benefits?

Yes! We work with manufacturers, OEMs, and distributors worldwide. Benefits include: ✔️ Priority production & stable pricing for long-term customers ✔️ Stocking agreements to prevent supply chain disruptions ✔️ Custom production & exclusive formulations upon request

Q: Can I get samples for testing?

Certainly! We often provide small quantities of samples free of charge for potential large customers. Let's discuss your specific needs with our sales team.

Q: What packaging options do you have?

25kg moisture-proof bags with PE lining. Palletized 1MT bundles or bulk containers. Custom labeling available for OEM buyers.

Key Properties of POM Resin

High Mechanical Strength & Rigidity

Exceptional tensile strength (60-70 MPa) and flexural modulus (2800-3100 MPa) make POM ideal for load-bearing components in automotive and industrial applications.

Superior Dimensional Stability

POM’s low moisture absorption (<0.25%) and minimal thermal expansion ensure precise fit and function in critical assemblies, even under varying environmental conditions.

Low Friction & Excellent Wear Resistance

With a coefficient of friction as low as 0.2, POM excels in high-wear scenarios, extending the lifespan of gears, bearings, and moving parts.

Chemical & Solvent Resistance

Highly resistant to a wide range of chemicals, making it suitable for fuel systems and industrial equipment.

Good Thermal Stability

Maintains performance across a broad temperature range (-50°C to 100°C), making it versatile for both cryogenic applications and high-temperature automotive components.

Excellent Electrical Properties

With high dielectric strength (20 kV/mm) and volume resistivity (1014 Ω·cm), POM is ideal for insulating components in electrical and electronic applications.

Applications of POM Plastic:

Automotive Industry (Fuel system components, door locks, seatbelt parts)

Industrial Applications (Gears, bushings, conveyor belts, bearings)

Electrical & Electronics (Switches, connectors, insulating parts)

Consumer Goods (Sporting goods, home appliances, zippers)

Precision Components (Fine mechanical parts, optical instruments)
