Welcome to Ailide Polymer (Jiangsu) Co., Ltd. — a dedicated manufacturer of high-performance engineering plastics with a factory spanning 1,000–3,000 square meters and a skilled team of 11–50 professionals. Our Standard Compliant POM K300 Engineering Plastic (Density 1.41 g/cm³, HDT 120°C) is specifically formulated for demanding oil pump components. This material combines the inherent lubricity of polyoxymethylene with enhanced thermal resistance, ensuring reliable operation in oil‑immersed environments. Whether you need precision gears, impellers, or housings, POM K300 delivers consistent performance and long service life.
Product Highlights & Technical Specifications
Our POM K300 is a standard‑compliant acetal copolymer grade that meets the rigorous requirements of oil pump applications. Below are key physical, mechanical, and thermal properties:
| Property | Value | Unit / Remark |
|---|---|---|
| Density | 1.41 | g/cm³ |
| Melt Flow Index (MFI) | 8–12 | g/10 min (190°C/2.16 kg) |
| Tensile Strength | 65 | MPa |
| Flexural Modulus | 2,600 | MPa |
| Notched Izod Impact Strength | 6 | kJ/m² |
| Heat Deflection Temperature (HDT) | 120 | °C (at 1.82 MPa) |
| Water Absorption (24h) | 0.2 | % |
Key Advantages for Oil Pump Parts
High Thermal Resistance: With an HDT of 120°C, this grade maintains dimensional stability even in hot oil circulation, preventing warpage or softening under pump operating temperatures.
Excellent Chemical Resistance: POM K300 resists hydrocarbons, lubricants, and many automotive fluids, ensuring long‑term reliability in oil pump environments.
Low Friction & Wear: The material's natural lubricity reduces friction between moving parts, minimizing energy loss and extending component life.
High Stiffness & Strength: A tensile strength of 65 MPa and flexural modulus of 2,600 MPa provide robust mechanical support for pressure‑bearing pump components.
Consistent Flow & Processability: MFI of 8–12 g/10 min allows stable injection molding, reducing cycle times and scrap rates.
Dimensional Stability: Low water absorption (0.2%) ensures parts retain their precise dimensions even in humid conditions, critical for pump sealing and clearance.
Benefits to Your Production
By choosing our Standard Compliant POM K300, you gain:
Cost Efficiency: Reduced maintenance intervals and longer part life lower total ownership cost.
Design Flexibility: Custom color options (natural, black, or RAL colors) and additive packages (e.g., UV stabilizers, lubricants) are available upon request.
Supply Reliability: As a manufacturer with direct control over our production line, we ensure consistent quality and on‑time delivery.
Technical Support: Our experienced engineers assist with mold design, processing parameters, and material selection to optimize your application.

Frequently Asked Questions (FAQ)
What is the difference between POM K300 and standard POM?
POM K300 is specifically formulated for oil pump applications with a higher HDT (120°C) and optimized density (1.41 g/cm³) to withstand thermal and mechanical stress in lubricant environments.Can this material be used for other automotive under‑hood parts?
Yes, its properties make it suitable for gears, bearings, housings, valve seats, and other components exposed to oils, fuels, or moderate heat.Is the color customizable?
Absolutely. We offer natural (white/translucent), black, and custom colors based on your requirement. Minimum order quantities may apply for custom colors.What processing conditions are recommended?
Typical injection molding temperatures range from 190–210°C, with mold temperatures of 60–80°C. We can provide detailed processing guidelines upon request.Does this grade contain any fillers or reinforcements?
No, POM K300 is an unfilled copolymer. If you require glass‑filled or lubricant‑modified versions, please inquire about our customized options.Is the material compliant with RoHS or REACH?
Our standard POM K300 meets common environmental regulations. Specific compliance documentation can be supplied upon request based on your target market.What is the typical lead time for orders?
For standard grades, lead time is 7–15 working days depending on quantity. Custom formulations may require 15–25 working days.Do you provide free samples for testing?
Yes, we offer free sample quantities (up to 5 kg) for qualified inquiries. Shipping costs are negotiable.
