DELRIN RODS,SHEETS & MACHINED COMPONENTS

Polyacetal sheets, plates and rods are among the strongest and stiffest of all thermoplastics. Polyacetal and Derlin plastic materials are characterized by good fatigue life, low moisture, sensitivity, and high resistance to solvents and chemicals. Polyacetal products also contain good electrical properties. Homo Polymer and Copolymer grade of Polyacetal are available including an enhanced bearing grade material.


Polyacetal - POM is a semi crystalline engineering plastic that is beneficial to engineering applications & is suited to CNC machining


Polyacetal Co-polymer, (POM-C) is more resistant against hydrolysis, strong alkalis and thermal oxidative degradation than the polyacetal homo-polymer (POM-H).


Polyacetal Homo-polymer (POM-H) has higher mechanical strength, stiffness, hardness and creep resistance as well as a lower thermal expansion rate when compared to polyacetal (POM-C) and often it also presents a better wear resistance.

Polyacetal is used in many static and dynamic industrial applications replacing materials like; steel, brass, bronze, copper and aluminium. Polyacetal have improved part life because of; better wear, more chemical & corrosion resistance.These materials reduce factory noise and will reduce or eliminate the need for lubricants
