Welcome to Ailide Polymer (Jiangsu) Co., Ltd. As a specialized manufacturer of engineering plastic raw materials, we are proud to present our POM K300 Acetal Copolymer Plastic Raw Material Granules – a premium-grade polyoxymethylene copolymer designed specifically for injection molding applications. With a factory spanning 1,000–3,000 square meters and a dedicated team of 11–50 experienced professionals, we ensure consistent quality and reliable supply to customers across North America, South America, Europe, Asia, Africa, and Oceania. Our POM K300 granules offer excellent mechanical properties, superior chemical resistance, and outstanding dimensional stability, making them the ideal choice for precision components in automotive, electronics, consumer goods, and industrial machinery.
This product is engineered to meet the demanding requirements of modern injection molding processes. Whether you are producing gears, bearings, housings, or intricate mechanical parts, our POM K300 provides the perfect balance of strength, stiffness, and lubricity. Read on to discover the technical details, processing advantages, and why Ailide Polymer is your trusted partner for high-performance acetal copolymer materials.
Key Features & Technical Specifications
High Mechanical Strength & Stiffness: POM K300 exhibits excellent tensile strength (approx. 60 MPa) and flexural modulus (around 2,500 MPa), ensuring durability under load.
Outstanding Dimensional Stability: Low moisture absorption (less than 0.3%) and minimal creep even at elevated temperatures – ideal for tight-tolerance parts.
Excellent Chemical Resistance: Resistant to hydrocarbons, solvents, and many chemical agents, making it suitable for automotive fuel systems and industrial applications.
Superior Lubricity & Wear Resistance: Low coefficient of friction (0.2–0.35) and high abrasion resistance reduce the need for external lubricants in moving parts.
Good Electrical Insulation: Dielectric strength above 20 kV/mm, suitable for electrical enclosures and connectors.
Easy Processing: Designed for injection molding with a wide processing window (melt temperature 180–210 °C, mold temperature 40–80 °C).
Consistent Granule Form: Uniform 3–5 mm pellets ensure smooth feeding and homogeneous melting in the barrel.

Advantages for Your Injection Molding Process
Faster Cycle Times: The optimized crystallization behavior of POM K300 allows for rapid cooling and ejection, reducing overall cycle time by up to 10% compared to standard grades.
Less Downtime: Excellent flowability (MFR ~8 g/10min at 190°C/2.16kg) ensures consistent filling of complex cavities, minimizing short shots and flash.
Reduced Scrap Rate: Tight molecular weight distribution results in uniform shrinkage and warpage control, leading to higher first-pass yield.
Low Odor & Low Emissions: Our copolymer process minimizes formaldehyde release, creating a safer working environment for your operators.
Customizable Color Options: Available in natural (off-white) as standard, but we can also supply pre-colored granules upon request to match your specific requirements.
Packing Flexibility: Supplied in 25 kg bags, 500 kg bulk bags, or customized packaging to suit your material handling system.
Compared to homopolymer acetal, our POM K300 copolymer offers superior thermal stability and chemical resistance, making it a more reliable choice for long-term applications. Whether you are molding automotive fuel system components, zippers, or household appliance parts, this grade delivers consistent performance batch after batch.

Frequently Asked Questions (FAQ)
What is the difference between POM K300 and general POM grades? POM K300 is a specially formulated acetal copolymer with optimized flow and mechanical properties for injection molding. It offers a good balance of strength, stiffness, and processability, making it suitable for a wide range of precision parts.
Can I use POM K300 for food contact applications? Our standard grade is designed for industrial use. If you require food-grade compliance, please contact us to discuss custom formulations and certifications that may be available upon request.
What is the recommended drying condition before injection molding? Although POM K300 has low moisture absorption, drying at 80–90 °C for 2–3 hours is recommended to ensure optimal processing and surface finish.
Does this material support overmolding or insert molding? Yes, POM K300 has good adhesion to metals and other plastics when properly prepared. We can provide processing guidelines for such applications.
What is the shelf life of POM K300 granules? When stored in a cool, dry place away from direct sunlight, the granules can be used for up to 12 months without significant degradation. Keep packaging sealed to avoid contamination.
Can you provide custom color matching? Absolutely. We offer color masterbatch addition and can produce pre-colored granules based on your Pantone or RAL code. Minimum order quantities may apply.
How do I request a sample? Simply send us an inquiry via our website or email, and we will arrange a complimentary 1 kg sample for evaluation. Shipping costs may apply depending on location.
What is your typical lead time for bulk orders? For standard POM K300, lead time is 10–15 working days after order confirmation. For custom colors or special packaging, please allow 15–20 working days.
