POM Granules: High - Performance Polyoxymethylene Engineering Plastic

Product Overview

Our POM (Polyoxymethylene) granules are a premium - grade engineering plastic raw material. POM, also known as acetal resin, is well - recognized for its outstanding mechanical, physical, and chemical properties. These granules are designed to meet the demanding requirements of various industries, offering a reliable solution for high - performance applications.

Key Features

Wear - Resistant

One of the most remarkable features of our POM granules is their excellent wear resistance. In applications where parts are subject to constant friction and abrasion, such as gears, bearings, and sliding components, these granules provide long - lasting performance. The wear - resistant property reduces the need for frequent replacements, thus saving costs and downtime in industrial operations.

Lubricating

The inherent lubricating characteristics of POM make it an ideal choice for applications that require smooth movement. Without the need for additional lubricants in many cases, POM parts can operate with low friction coefficients. This not only simplifies the design and maintenance of machinery but also reduces the risk of contamination caused by external lubricants.

High Mechanical Strength

POM granules offer high tensile strength, stiffness, and impact resistance. This enables the production of parts that can withstand heavy loads and stress. For example, in automotive and construction applications, POM - made components can endure the rigors of daily use and harsh environments, ensuring the structural integrity and reliability of the overall system.

Chemical Resistance

These granules exhibit good resistance to a wide range of chemicals, including solvents, fuels, and weak acids. This chemical resistance makes POM suitable for use in chemical processing plants, fuel systems, and other applications where contact with corrosive substances is likely.

Dimensional Stability

POM has excellent dimensional stability, meaning that parts made from these granules maintain their shape and size even under varying temperature and humidity conditions. This is crucial for precision - engineered components, such as those used in electronics and precision machinery, where tight tolerances are required.

Technical Specifications

• Melting Point: Approximately 165 - 175°C. This relatively high melting point allows for processing at elevated temperatures without significant degradation of the material.
• Density: Around 1.41 - 1.43 g/cm3. The specific density of POM contributes to its mechanical properties and can be an important factor in applications where weight is a consideration.
• Melt Flow Index (MFI): Varies depending on the grade, typically in the range of 2 - 30 g/10 min. The MFI determines the flowability of the molten POM during the injection molding or extrusion process, enabling manufacturers to select the appropriate grade for their specific processing requirements.

Applications

• Automotive Industry: POM is used in various automotive components, such as fuel system parts, door lock mechanisms, and gearshift components. Its wear resistance, lubricating properties, and chemical resistance make it a reliable choice for these critical applications.
• Electronics and Electrical Appliances: In the electronics sector, POM is used for connectors, switches, and insulators. Its dimensional stability and electrical insulation properties ensure the proper functioning of electronic devices.
• Consumer Goods: Items like zippers, handles, and small household appliances often incorporate POM parts due to its aesthetic appeal, durability, and ease of processing.
• Industrial Machinery: Gears, bearings, and conveyor components are commonly made from POM. The high mechanical strength and wear resistance of POM ensure smooth operation and long service life in industrial settings.

Processing

Our POM granules are suitable for a variety of processing methods, including injection molding, extrusion, and blow molding. Before processing, it is recommended to dry the granules at a temperature of around 80 - 100°C for 3 - 4 hours to remove any moisture. This helps to prevent defects such as voids and surface imperfections in the final products.
