Low Temperature Modified Polyoxymethylene

Updated: 2026-08-18

Overview

Low-temperature modified polyoxymethylene (POM) is a high-performance engineering thermoplastic engineered to retain mechanical properties in subzero environments. Unlike standard POM, it incorporates impact modifiers and stabilizers to prevent brittleness at temperatures as low as -40°C. Originally developed for aerospace applications, this material now serves industries requiring precision parts with reliable cold-weather performance. Its molecular structure combines formaldehyde polymers with tailored additives, balancing rigidity and low-temperature toughness.

Physical and Chemical Properties

The modified POM exhibits a crystalline structure with 75-85% crystallinity, contributing to its dimensional stability. Key enhancements include a 30-50% improvement in Charpy impact strength at -30°C compared to unmodified grades. Chemical resistance remains comparable to standard POM, with excellent resistance to hydrocarbons, alcohols, and weak acids. However, prolonged exposure to strong acids or UV radiation may degrade performance. The material maintains a low coefficient of friction (0.1-0.3) even in cold conditions.

Main Applications

Automotive systems represent the largest application sector, particularly for fuel system components, door latch mechanisms, and exterior trim parts in cold climates. Industrial uses include conveyor belt components, refrigeration system gears, and agricultural machinery parts. In consumer goods, modified POM appears in winter sports equipment, cold-storage device components, and precision instrument housings. Medical applications are limited due to formaldehyde emission concerns but may include sterilizable cold-chain containers.

Safety and Storage

While generally stable, thermal processing above 200°C can release formaldehyde vapors. Adequate ventilation and personal protective equipment (PPE) are recommended during injection molding or machining operations. Storage requires protection from moisture absorption (max 0.2% water content) to prevent processing defects. Bulk material should be stored in sealed containers with desiccants. Shelf life typically exceeds 24 months when properly stored.

B2B Procurement Guide

Industrial buyers should specify required cold-temperature performance metrics, typically measured by ISO 6603-2 impact tests at target temperatures. Volume discounts commonly apply for orders exceeding 5 metric tons. Leading manufacturers include Celanese (Hostaform® LT), DuPont (Delrin® 100ST), and Mitsubishi Engineering-Plastics (Iupital®). Quality verification should include certificates for ISO 9001 and material datasheets with low-temperature mechanical data.
