Interstate Specialty Products die cuts non-metallic washers for medtech, electronics, and industrial applications.

Non-metallic washers made from rubber or plastic cost less than metal washers and can be custom manufactured in sizes from 0.100” outer diameter (OD) and from 0.005” to 0.12” thick. Applications for non-metallic washers include pumps, valves, compressors, electric motors, and oil and gas equipment.

Types of Non-Metallic Washers

Washers are made of many different materials and are used for sealing, spacing, insulating, and vibration absorption. For example:

  • Acetal and Delrin washers offer good chemical resistance.
  • Epoxy glass washers feature excellent mechanical strength and electrical properties.
  • Fish paper washers have strong dielectric properties.
  • Mylar washers combine dielectric strength with moisture resistance.
  • Nylon and nylatron washers have good bearing and anti-friction characteristics.
  • Phenolic washers are a good choice for toughness and corrosion resistance.
  • Polyethyelene washers combine toughness with good barrier properties.
  • Polypropylene washers combine mechanical strength with wear resistance.
  • PTFE washers resist friction and chemicals.
  • UHMW washers combine abrasion resistance with impact strength.
  • Vulcanized fiber washers have a smooth, abrasion resistant surface.
  • Silicone washers are a good choice for higher-temperature applications.
  • EPDM washers have outstanding ozone resistance.*
