Black Acetal Rods are semi-crystalline engineering thermoplastics made by the polymerization of formaldehyde. They have physical properties that are not available with metals and plastics It provides 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, which make them good for electrical applications. The feature include High strength & stiffness, low friction, good dimensional stability, low moisture absorption, performs both in wet and dry environments and good electrical properties. It provides excellent machinability,dimensional Stability, tough and impact resistant.
