Detailed Product Description
Our POM K300 injection molding material is a high-performance acetal copolymer specifically designed for automotive interior clips and door lock components. The material’s low friction properties ensure smooth sliding and snap-fit actions without squeaking or sticking, which is critical for user experience in vehicle cabins. The high crystallinity of POM K300 provides excellent stiffness and creep resistance, maintaining tight tolerances even under temperature fluctuations and constant load.
Compared to standard POM grades, the K300 variant offers enhanced wear resistance and a lower coefficient of friction, reducing the need for lubricants in door lock mechanisms. This makes it an ideal choice for interior trim clips, door lock housings, latch components, and fastening systems. The material processes easily on conventional injection molding machines, with recommended mold temperatures of 80–100°C and melt temperatures of 190–210°C. It exhibits minimal shrinkage and warpage, allowing for high-precision part production.
For customers requiring color matching, we offer custom color formulations (e.g., black, gray, beige) to blend seamlessly with vehicle interiors. The material is also compatible with typical automotive testing requirements such as UV resistance and thermal aging. Our technical team can provide processing guidelines and material data sheets to support your production.

Frequently Asked Questions
-
Q: What is the continuous use temperature range for POM K300?
A: POM K300 can typically withstand continuous service temperatures from -40°C to +100°C, with short-term peaks up to 140°C. For specific applications, please consult our technical team. -
Q: Does this material require drying before injection molding?
A: Yes, we recommend drying POM K300 at 80–90°C for 3–4 hours to achieve a moisture content below 0.15% for optimal processing. -
Q: Can I get custom colors for automotive interior clips?
A: Absolutely. We offer color matching services. Please provide a RAL or Pantone code, and we will formulate the material accordingly. -
Q: Is POM K300 suitable for snap-fit designs?
A: Yes, its excellent flexibility and fatigue resistance make it ideal for snap-fit clips and latches commonly used in automotive interiors. -
Q: What certifications or test reports can you provide?
A: We can provide material physical property reports, RoHS, REACH compliance declarations, and other relevant documentation as required. Specific automotive standards can be discussed with our engineers. -
Q: What is the minimum order quantity (MOQ)?
A: MOQ depends on the grade and color. Typically, standard natural POM K300 starts at 500 kg per order. Custom colors may require a larger minimum. Contact us for details. -
Q: How does POM K300 compare to POM with PTFE lubrication?
A: POM K300 achieves low friction through internal modification without PTFE fillers, offering a cost-effective solution with good wear resistance and no risk of PTFE segregation. -
Q: Can this material be used for external automotive parts?
A: It is primarily designed for interior applications. For exterior exposure (UV, weather), we recommend our UV-stabilized POM grades. Please inquire for exterior-specific solutions.
