Polyisoprene Gaskets

Precision die-cut polyisoprene components. ISO 9001 certified. Fontana, CA since 1971.
Custom polyisoprene rubber gaskets, synthetic natural rubber with consistent chemistry and FDA-grade options for medical and food applications.

Key Properties

  • Durometer
  • Latex-free alternative
  • Excellent tensile strength
  • FDA & medical grades
  • High resilience

Why specify Polyisoprene for gaskets?

Polyisoprene is the synthetic equivalent of natural rubber, offering similar mechanical properties without the variability and latex protein content of plant-derived natural rubber. Cannon Gasket die-cuts custom polyisoprene gaskets for medical, food, and industrial applications where consistent chemistry and FDA compliance matter.

Properties of Polyisoprene gaskets

Cannon Gasket cuts Polyisoprene gaskets to your drawing in durometer and thickness specifications of 30A to 80A Shore hardness. Good resistance to water, dilute acids, and alcohols. Not recommended for petroleum oils, fuels, or strong oxidizing agents.

Polyisoprene tolerances and customization

Standard dimensional tolerances on Polyisoprene gasketsland around ±0.010" to ±0.015" on OD and ID, depending on material durometer and thickness. Tighter tolerances are available on select grades. Cannon Gasket cuts Polyisoprene to custom profiles in-house and matches lead times to your production volume. PSA backing, pad printing, custom packaging, and kitting are all on the menu when you need them.

How Polyisoprene Performs

- Mechanical properties similar to natural rubber — high resilience, good tear strength, low compression set. - Latex-protein-free formulations available for medical use. - FDA and medical-grade compounds available.

Where Polyisoprene Gaskets Are Specified

Medical device gaskets, pharmaceutical equipment, food and beverage seals, latex-sensitive applications, and assemblies where natural rubber's chemistry is desired without the inconsistency of plant-derived stock.

When to Choose Another Material

For oil contact specify Buna-N. For outdoor / ozone exposure specify EPDM. For high temperature specify silicone.
