Acetal polymers, referred to chemically as POM PolyOxyMethylene, are semi-crystalline engineering thermoplastics made by the polymerization of formaldehyde. They have physical properties that are not available with metals or most other plastics; high mechanical strength and rigidity, low coefficients of friction, low moisture absorption, excellent dimensional stability, fatigue endurance, and resistance to abrasion and creep. These materials are also resistant to a wide range of solvents and have good electrical properties.

•  Bearings, bushings, wear pads
•  Gears
•  Electrical components
•  Jigs and fixtures
•  Pump and valve parts
•  Medical components

Characteristics
•  Low moisture absorption
•  Low coefficient of friction

Acetal MX-D metal and x-ray detectable shapes are made from Acetal (polyoxymethylene, POM) infused with detectable additives, such as metal particles or X-ray-visible compounds. These shapes are designed for use in industries like food processing, pharmaceuticals, and packaging, where contamination detection is critical.

Key Characteristics:

• Detectability: Embedded additives allow detection by metal detectors and X-ray systems, ensuring any fragments or parts contaminating products can be identified and removed.
• Material Properties: Acetal provides high strength, stiffness, and low friction, with excellent dimensional stability and resistance to wear, chemicals, and moisture.
• Applications: Used for conveyor components, gears, rollers, bearings, and other parts in environments requiring hygiene and safety compliance (e.g., FDA, USDA, or EU food-contact regulations).
• Color: Typically available in distinct colors like blue to aid visual identification, though color may vary based on manufacturer.
• Machinability: Easily machined into precise shapes while maintaining tight tolerances.
• Temperature Resistance: Operates effectively in a range of -40°C to 80°C (-40°F to 176°F), though specific limits depend on the formulation.
• Durability: Resistant to abrasion and impact, ensuring long service life in demanding applications.

These shapes combine acetal’s robust mechanical properties with enhanced safety features, making them ideal for critical applications where contamination risks must be minimized.

HPV13 is a brown homopolymer acetal with an internal PTFE lubricant. Its low coefficient of friction, excellent PV values, toughness, wear resistance, and machinability make it an exceptional material for use in many industrial and military components with moving parts. Additionally, HPV13 has superior chemical resistance and flexural fatigue properties, as well as low moisture absorption associated with acetal materials,

PTFE-Filled Acetal Shapes

Overview:
PTFE-filled Acetal (also known as PTFE-enhanced POM or PTFE-blended acetal) is a high-performance engineering plastic designed for applications requiring low friction, enhanced wear resistance, and excellent dimensional stability.

ESD Acetal shapes are characterized by their excellent wear resistance, thermal performance, and ability to quickly dissipate static charges. This modified Acetal produces a defined degree of conductivity in the static-dissipative range with a surface resistivity 10⁸-10¹⁰ ohm/square. Due to these properties, this grade is ideal for several applications throughout the semiconductor and electronics industry, such as hard disk drive fixtures, high speed electronic printing components, jigs and fixtures for static control, and wafer processing components.

Product Information

Anti-static Acetal shapes contain an anti-static additive. This modified Acetal produces a defined degree of conductivity in the anti-static range with a surface resistivity 10¹⁰-10¹² Ohm/square. However, the addition of the anti-static agent can compromise the strength and hardness of the material depending on the application. Anti-static Acetal shapes offer good wear resistance, high chemical resistance, and has high toughness and strength.
