Ailide Polymer (Jiangsu) Co., Ltd., a dedicated manufacturer with over 10 years of experience in engineering plastics, proudly presents the Formosa FM090 Copolyacetal – a premium-grade acetal copolymer specially formulated to deliver low shrinkage variation for small precision molded parts. Our factory, located in Nantong, Jiangsu, occupies 1,000–3,000 sqm and employs an experienced team of 11–50 professionals, ensuring consistent quality and reliable supply. With export markets spanning North America, Europe, Southeast Asia, and beyond, we understand the critical demands of miniaturized components where dimensional stability is non-negotiable. This material is the ideal choice for manufacturers seeking tight tolerances and repeatable performance in high-volume production.
Key Features & Technical Specifications
Low Shrinkage Variation: The FM090 grade exhibits a shrinkage rate of only 0.1%–0.2%, significantly reducing post-molding warpage and ensuring consistent part dimensions across cavities.
Excellent Flowability: Designed for thin-wall and micro-molding applications, the material fills intricate cavities with ease, minimizing short shots and weld lines.
High Mechanical Strength: Retains excellent tensile strength (approx. 60 MPa) and impact resistance, suitable for gears, bushings, and connectors.
Chemical & Wear Resistance: Resists fuels, oils, and solvents, while offering low coefficient of friction for moving parts.
Thermal Stability: Processing temperature range 180–210°C, with a melting point of approximately 165°C, suitable for standard injection molding machines.
Regrind Compatibility: Up to 20% regrind can be blended without compromising properties, reducing material costs.

Frequently Asked Questions
What is the difference between FM090 and standard acetal copolymer?
FM090 is specially formulated to have minimal shrinkage variation (≤0.2%), while standard POM copolymers typically exhibit 0.5–2% shrinkage. This makes FM090 ideal for parts with tight tolerances.Can this material be used for food contact applications?
FM090 is not specifically certified for food contact. If you require food-grade compliance, please inquire about our special grades with FDA or EU approval (available upon request).What is the recommended drying condition before molding?
Drying is not usually required for POM, but if moisture is present (e.g., after long storage), we recommend drying at 80–90°C for 2–4 hours.How does FM090 perform in high-temperature environments?
Continuous use temperature is around 100°C. For short-term exposure, it can withstand up to 140°C. For higher temperature requirements, consider our heat-stabilized grades.Can I mix FM090 with other colors or additives?
Yes, we offer color masterbatch compounding and additive packages (e.g., UV stabilizers, lubricants) as customization options. Minimum order quantity may apply.What is the typical lead time for orders?
For standard FM090 (natural color), we ship within 5–7 working days after receipt of payment. Customized colors or additives may take 10–15 days.Do you provide technical support for molding issues?
Absolutely. Our experienced engineers can offer guidance on gate design, mold temperature, and processing parameters to optimize your results.Is FM090 suitable for glass-filled or reinforced composites?
FM090 is a neat copolyacetal. For glass-reinforced versions, we offer other grades like FM090-GF15 or GF30. Please contact us for details.
