Ailide Polymer (Jiangsu) Co., Ltd. is a professional manufacturer dedicated to the production of high-quality engineering plastics. Our POM K300 Medium Viscosity High Rigidity Wear-Resistant Polyformaldehyde Plastic Particles are designed to meet the toughest demands of industrial applications. With a factory spanning 1,000–3,000 square meters and a team of 11–50 experienced employees, we ensure consistent quality and reliable supply for global markets including North America, Europe, Asia, and beyond.
POM K300 is a medium-viscosity grade homopolymer acetal resin that offers an excellent balance of mechanical strength, dimensional stability, and wear resistance. It is specifically formulated for applications requiring high rigidity and low friction, making it ideal for precision parts, gears, bearings, and automotive components. Our material is processed under strict quality control to ensure batch-to-batch consistency, enabling smooth injection molding and extrusion operations.
Key Features & Benefits
High Rigidity: Exceptional stiffness and creep resistance ensure long-term dimensional stability under load.
Wear Resistance: Outstanding abrasion resistance reduces part wear and extends service life, even in high-speed sliding applications.
Medium Viscosity: Optimized flow characteristics for easy processing – suitable for both thin-wall and thick-section injection molding.
Low Friction: Self-lubricating properties eliminate the need for external lubricants in many moving parts.
Chemical Resistance: Excellent resistance to organic solvents, fuels, and weak acids, making it suitable for automotive and industrial environments.
Good Electrical Insulation: Stable dielectric properties support use in electrical and electronic components.
Color Options: Available in natural (white/translucent) and can be customized to specific color requirements.

Processing Guidelines
POM K300 is primarily processed by injection molding. Recommended cylinder temperatures range from 190°C to 220°C, with mold temperatures between 60°C and 80°C. The material is hygroscopic and should be pre-dried at 80°C for 2–4 hours before processing. For extrusion, a similar temperature profile can be used. Our technical team can provide detailed processing recommendations upon request.

Frequently Asked Questions
Q1: What is the difference between POM K300 and standard POM grades?
A: POM K300 is a medium-viscosity homopolymer with enhanced rigidity and wear resistance compared to general-purpose copolymers. It offers higher stiffness and better dimensional stability, making it suitable for demanding mechanical parts.
Q2: Can POM K300 be used for food contact applications?
A: Standard POM grades are not recommended for direct food contact unless explicitly certified. Please consult with our technical team for specific compliance requirements in your region.
Q3: What is the recommended drying condition before processing?
A: Pre-drying at 80°C for 2–4 hours is recommended to keep moisture content below 0.1%. Excessive moisture can cause surface defects and brittleness.
Q4: Is the material UV-resistant?
A: POM is inherently sensitive to UV radiation. For outdoor applications, we recommend UV-stabilized grades or post-processing surface treatments. Custom formulations are available upon request.
Q5: What is the typical shrinkage rate of POM K300?
A: Mold shrinkage is typically in the range of 1.8%–2.5%. Actual shrinkage depends on part geometry, processing conditions, and mold design. We recommend using simulation tools for precise predictions.
Q6: Can I get a sample before placing a bulk order?
A: Yes, we provide free samples (up to 1 kg) for testing. Please contact our sales team with your shipping details, and we will arrange delivery.
Q7: What is the minimum order quantity (MOQ)?
A: Our standard MOQ is 500 kg per grade. For smaller quantities or first-time trials, we can accommodate special requests. Please inquire.
Q8: How do you ensure product quality consistency?
A: We implement in-process quality control and final inspection using standardized test methods (ISO, ASTM). Each batch is tested for MFR, tensile strength, and impact properties before shipment. A certificate of analysis is provided with every order.
