Overview
20% Glass-Fiber Reinforced POM is a thermoplastic polymer enhanced with 20% glass fibers to improve its mechanical properties. Polyoxymethylene (POM), commonly known as acetal or Delrin, is prized for its high strength, rigidity, and resistance to wear and chemicals. The addition of glass fibers significantly boosts its tensile strength and dimensional stability, making it suitable for demanding engineering applications. This material is widely used in industries requiring precision parts that must withstand mechanical stress and environmental factors. Its low friction coefficient and excellent fatigue resistance make it ideal for gears, bearings, and other moving components. The glass-fiber reinforcement also reduces thermal expansion, ensuring consistent performance across temperature variations.
Physical and Chemical Properties
20% Glass-Fiber Reinforced POM exhibits a density of approximately 1.54 g/cm³, which is higher than unfilled POM due to the glass fibers. Its melting point ranges between 165-175°C, and it maintains structural integrity up to this temperature. The material is insoluble in water and resistant to most organic solvents, acids, and bases, making it suitable for harsh environments. The glass fibers enhance the material's tensile strength, flexural modulus, and impact resistance. It also demonstrates low moisture absorption, which contributes to its dimensional stability. However, prolonged exposure to UV radiation or strong acids can degrade its properties, so protective coatings or additives may be necessary for outdoor use.
Main Applications
This material is extensively used in the automotive industry for components such as fuel system parts, door handles, and seatbelt mechanisms. Its high strength-to-weight ratio and resistance to fuels and lubricants make it a preferred choice for under-the-hood applications. In industrial settings, 20% Glass-Fiber Reinforced POM is employed in gears, bearings, and conveyor system parts due to its low friction and wear resistance. Consumer goods like zippers, fasteners, and kitchen appliance parts also benefit from its durability and smooth surface finish. Additionally, it is used in electrical insulators and connectors for its dielectric properties.
Safety and Storage
When handling 20% Glass-Fiber Reinforced POM, it is important to avoid inhaling dust particles, which can irritate the respiratory system. Use personal protective equipment (PPE) such as gloves and masks when processing the material, especially during machining or melting. Store the material in a cool, dry environment away from direct sunlight and moisture to prevent degradation. Properly sealed containers or bags are recommended to maintain its properties. Avoid exposure to strong oxidizing agents or acids, which can compromise the material's integrity.
B2B Procurement Guide
When procuring 20% Glass-Fiber Reinforced POM, verify the glass-fiber content and mechanical property specifications to ensure they meet your application requirements. Request material data sheets (MDS) and certificates of analysis (CoA) from suppliers to confirm quality standards. Consider the material's processing conditions, such as injection molding or extrusion temperatures, to avoid defects like warping or voids. Bulk purchasing may offer cost advantages, but ensure proper storage conditions to maintain material quality. For reference, the price ranges between $3.5-$5.0 per kg, though prices may vary based on supplier and order volume.
