Overview
High viscosity POM (Polyoxymethylene) is a premium engineering thermoplastic renowned for its exceptional mechanical properties and chemical resistance. It is a semi-crystalline polymer with high stiffness, low friction, and outstanding dimensional stability, making it ideal for precision applications. POM materials are categorized into homopolymer and copolymer forms, with high viscosity grades offering enhanced flow characteristics during processing. This material is widely used in industries requiring durable, wear-resistant components, such as automotive, electronics, and industrial machinery.
Physical and Chemical Properties
High viscosity POM exhibits a density of 1.41-1.42 g/cm³ and a melting point range of 165-175°C. Its low moisture absorption and excellent creep resistance make it suitable for long-term use under mechanical stress. The material is chemically resistant to hydrocarbons, alcohols, and weak acids but may degrade in strong acids or oxidizing agents. Its high crystallinity contributes to its superior mechanical strength and thermal stability, even in demanding environments.
Main Applications
High viscosity POM is extensively used in precision mechanical parts, such as gears, bearings, and bushings, due to its low friction and wear resistance. In the automotive industry, it is employed in fuel system components, seatbelt mechanisms, and door handles. Industrial applications include conveyor belts, pump components, and electrical insulators. Its dimensional stability and ease of machining also make it a preferred choice for prototyping and custom parts in engineering projects.
Safety and Storage
POM materials should be stored in a dry, cool environment to prevent degradation. Exposure to high temperatures or UV light can affect its properties, so protective packaging is recommended. During processing, adequate ventilation is necessary to avoid inhalation of fumes. Personal protective equipment (PPE), such as gloves and masks, should be used when handling raw granules or machining finished parts.
B2B Procurement Guide
When procuring high viscosity POM, buyers should specify the required viscosity grade, thermal stability, and any additives (e.g., UV stabilizers or lubricants). Certifications such as ISO 9001 or RoHS compliance should be verified with suppliers. Bulk purchases typically offer cost advantages, with prices ranging approximately $2.5-$4.5 per kg. Consider lead times and supplier reliability, especially for just-in-time manufacturing. Sample testing is advisable to ensure material meets application-specific performance criteria.
