Benefits For Your Manufacturing
- Faster Production: Good flowability reduces fill time and enables thinner wall sections without sacrificing strength.
- Lower Reject Rate: Consistent shrinkage and low warpage minimize dimensional defects in complex parts.
- Cost Efficiency: Extended tool life due to lower abrasiveness compared to glass-filled grades, and fewer part failures in the field.
- Design Flexibility: Suitable for intricate geometries, snap-fit hooks, and thin-wall connectors used in electrical housings.
- Sustainable Option: POM copolymer can be reground and reused in many non-critical applications, reducing material waste.

Frequently Asked Questions
Q1: What is the difference between KOCETAL K300 and standard POM homopolymer?
K300 is a copolymer, which offers better thermal and chemical resistance during processing, reduced center-line porosity, and improved long-term aging behavior. It is especially suited for snap-fit parts because it can flex repeatedly without brittle failure.
Q2: Can K300 be used for food-contact applications?
Regulatory compliance depends on your final part geometry and processing conditions. We recommend checking with your local food-safety authority or contacting us for a material declaration. Specific grades with food-contact approvals may be available upon request.
Q3: What injection molding temperature range should I use?
Typical barrel temperature settings are 190–230 °C, with mold temperatures around 40–80 °C. We recommend optimizing with a molding trial and consulting the technical datasheet provided by the resin manufacturer.
Q4: Is K300 suitable for glass-filled or reinforced compounds?
K300 is a base resin. For reinforced grades, you may need a compounder who can add glass fiber or other fillers. We can also supply modified compounds based on your performance target, subject to minimum order quantities.
Q5: How should I dry KOCETAL K300 before molding?
Although POM copolymer is less hygroscopic than nylon, drying is still recommended to avoid surface defects. Use a hopper dryer at 80–90 °C for 2–4 hours. Moisture content should be below 0.1% before processing.
Q6: Can I get a custom color or UV-stabilized version?
Yes, we offer color matching and UV-stabilized options for outdoor applications. These custom versions are available upon request with a small development lead time.
Q7: What packaging options are available?
Standard packaging is 25 kg multi-wall paper bags with a polyethylene liner. We also offer 500 kg bulk bags for large-volume users. Packaging can be customized to your handling system.
Q8: Do you provide free samples for testing?
Yes, we can supply evaluation samples of KOCETAL K300. Please contact our sales team with your shipping details and intended application, and we will arrange a sample shipment.
As a manufacturer with deep experience in polymer supply, we aim to build long-term partnerships with molders, distributors, and brand owners around the world.
