Plastic Shims

Plastic Shims

Plastic shims are made of polyester plastic and have become increasingly recognised in engineering for shimming, spacing and insulation applications. The unique colour coding of plastic shims denotes the material thickness, eliminating the need to use a micrometre. Plastic shims have excellent wear resistance with a high strength-to-weight ratio making them a popular alternative to metallic shimming materials. 

Key Features of Plastic Shims

  • High tear resistance and tensile strength.
  • Resistant to abrasion and impact.
  • Dimensionally stable.
  • Easily fabricated and safer to use than most standard shimming materials.
