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.

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

Characteristics
•  Low moisture absorption
•  Low coefficient of friction
•  High strength and stiffness
•  Excellent electrical properties
•  Good chemical resistance
•  Easy to fabricate

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.
