Delrin Balls


Product Description

We are a well recognized acetal delrin balls manufacturer and supplier in India. Our delrin plastic balls are very much popular in the market worldwide. With the help of our advanced integrated technology we are able to produce high quality delrin balls.

GENERAL PROPERTIES
Acetal is the common name for a family of thermoplastics with the chemical name “PolyOxy-Methylene”. Acetal provides high strength and stiffness, enhanced dimensional stability, and is easy to machine. As a semi-crystalline material, acetal is characterized by a low coefficient of friction and good wear properties.

FEATURES
  • High strength, stiffness, dimensional stability
  • Very low moisture absorption
  • Good wear and abrasion resistance
  • Wide range chemical resistance (including many solvents)
