Frequently Asked Questions (FAQ)
- What is the difference between POM K300 and other POM grades? — K300 has a melt flow index of 9 g/10 min, which offers a good balance between flowability and mechanical strength. Lower MFI grades (e.g., 3–5) are used for high-strength applications, while higher MFI grades (e.g., 15–25) are for thin-wall molding. K300 is a versatile general-purpose injection molding grade.
- Can I use POM K300 for extrusion? — This grade is optimized for injection molding. For extrusion applications, we recommend our POM extrusion grades with lower MFI values. Please consult our technical team for guidance.
- What is the recommended drying condition before molding? — POM K300 is generally supplied in sealed bags and does not require drying. However, if the material has been exposed to moisture, drying at 80–90°C for 2–4 hours is recommended to achieve optimal surface finish.
- Is the product RoHS compliant? — Yes, our POM K300 meets the RoHS directive requirements for restricted hazardous substances. Compliance certificates are available upon request.
- Do you offer free samples for testing? — Yes, we provide free samples (up to 5 kg) for qualified customers. You only need to cover the shipping cost. Please contact our sales team to arrange.
- What is the minimum order quantity (MOQ)? — For standard natural color, the MOQ is 100 kg. For customized colors, the MOQ is 500 kg. We can also accommodate smaller trial orders for new customers.
- How long does delivery take? — For stock items, delivery takes 3–7 working days after payment confirmation. For production orders, lead time is typically 7–15 working days depending on the quantity.
- Can you provide a Certificate of Analysis (COA) with each shipment? — Absolutely. Every batch is tested before shipment, and a COA with detailed physical and mechanical properties is included in the packing.
