Ailide Polymer (Jiangsu) Co., Ltd. is proud to introduce our POM FM090 LMD Low Mold Deposit Acetal Copolymer, a specialized engineering plastic designed to meet the demanding requirements of clean production processes. As a manufacturer with over a decade of experience in the polymer industry, we have developed this grade to address common challenges in injection molding — particularly mold deposit buildup and contamination. With a factory spanning 1,000–3,000 square meters in Nantong, China, and a team of 11–50 skilled professionals, we serve global markets including North America, Europe, Asia, and the Middle East. Our FM090 LMD grade is the result of advanced copolymer technology that minimizes plateout and deposit formation, ensuring longer tool life, reduced downtime, and consistent product quality.
Key Features & Benefits
- Low Mold Deposit (LMD) Technology: Specially formulated acetal copolymer reduces the formation of mold deposits (plateout) during injection molding, which is critical for maintaining high surface finish and dimensional accuracy over long production runs.
- Clean Production Compatibility: Ideal for applications where contamination must be minimized, such as food contact, medical devices, optical components, and high-cleanliness automotive parts.
- Excellent Mechanical Properties: High stiffness, low friction, and good creep resistance typical of POM copolymers, with tensile strength around 65 MPa and flexural modulus of 2,400 MPa (typical values).
- Thermal Stability: Wide processing window (180–210°C) allows for easy molding without degradation, reducing the risk of gas emission and deposit formation.
- Consistent Melt Flow: With a melt flow rate of approx. 9 g/10min (190°C/2.16kg), this grade ensures balanced filling in multi-cavity molds.
- Reduced Cycle Time: The optimized rheology enables faster cooling and shorter cycle times compared to standard POM grades, contributing to higher productivity.
- Broad Color Options: Available in natural (translucent white) and black, with custom color matching available upon request for brand-specific applications.
- Global Supply Chain: Shipped from our Nantong facility with reliable lead times; samples can be provided for pre-production validation.

Application Advantages
The FM090 LMD grade is specifically engineered for applications that demand a clean molding environment. Traditional acetal copolymers often produce a white deposit on mold surfaces over time, requiring frequent mold cleaning and causing part rejects. Our Low Mold Deposit technology reduces this phenomenon by up to 80%, based on internal trials. This translates to:
- Extended mold maintenance intervals — from every 4-6 hours to over 20 hours of continuous production.
- Higher yield and fewer defective parts due to reduced contamination on critical surfaces.
- Improved surface gloss and clarity for transparent or light-colored products.
- Less downtime and reduced labor costs associated with mold cleaning.

Frequently Asked Questions (FAQ)
Q1: What makes FM090 LMD different from standard POM copolymers?
A: FM090 LMD incorporates a specially designed additive package that suppresses the formation of mold deposits (plateout) typically seen during high-volume injection molding. This results in cleaner molds, fewer part defects, and longer production runs without shutdown for cleaning.
Q2: Can FM090 LMD be used for food contact applications?
A: This grade is formulated to meet clean production requirements, but specific food contact regulations vary by region (e.g., FDA, EU 10/2011). Please contact us with your application details so we can provide compliance information or recommend an appropriate grade.
Q3: What is the recommended processing temperature range?
A: The optimal melt temperature is 180–210°C. Mold temperature should be set between 60–90°C. Drying is not usually required for POM copolymer, but if stored improperly, a pre-drying at 80°C for 2–4 hours is recommended.
Q4: How do you prove reduction in mold deposit?
A: We have conducted internal comparative tests using a standardized injection mold. Under identical conditions, FM090 LMD showed significantly less white residue after 8 hours of continuous cycling compared to a standard POM copolymer. We can share test data and videos upon request.
Q5: Is this material available in custom colors?
A: Yes, we offer color matching services for orders above a minimum quantity. Standard colors are natural (translucent) and black. Custom colors can be developed with a lead time of 2–4 weeks.
Q6: What is the minimum order quantity (MOQ)?
A: For standard grades, MOQ is 500 kg. For sample requests, we provide 5 kg free of charge (shipping cost may apply). Larger orders can be arranged based on your schedule.
Q7: Does FM090 LMD have any impact on mechanical properties?
A: The low mold deposit additives are carefully selected to minimize any negative effect on mechanical performance. Typical data shows tensile strength, impact strength, and modulus are comparable to standard POM copolymers of similar MFR. Full data sheets are available.
Q8: How long does it take to receive samples?
A: For domestic clients in China, samples arrive within 2–3 working days. For international shipments, typical delivery is 5–8 working days via express courier (DHL, FedEx, UPS).
At Ailide Polymer, we are dedicated to delivering high-performance engineering plastics that solve real manufacturing challenges.
