Kalrez: high quality seals

Kalrez® can help you optimize your total system cost in pumps and process equipment.
When we compare the total cost, in relation to sealing solutions, Kalrez® parts are often the most efficient choice. They: 

  • last longer;
  • are reducing downtime and increasing MTBR;
  • will add to increase safety on production sites;
  • help to avoid unplanned leakages;
  • help to reduce environmental risks. 

These properties make Kalrez® perfluoroelastomer parts a preferred choice for critical sealing applications.

Fluid and chemical resistance of Kalrez®

Kalrez® perfluoroelastomer parts withstands more than 1,800 chemicals, solvents and plasmas. Standardizing with Kalrez® products for broad chemical resistance, reduces your needs to keep multiple materials in stock and therefore will lower the cost of your inventory.

Sealing force retention

We have established in ISO 3384 tests that even under harsh and aggressive conditions, Kalrez® will
retain its sealing force longer than similar products. Because Kalrez® Spectrum™ 7075 parts recover
better under compression than many other perfluoroelastomers, they tend to maintain their shape better under prolonged stress.

Great temperature resistance

In our experience, Kalrez® retains its elasticity and recovery properties better than other high
temperature elastomers. Kalrez® Spectrum™ 7075 retains it even after long-term exposure to
temperatures up to 327°C.

Excellent elastic properties

In addition, Kalrez® is a thermoset perfluoroelastomer and offers excellent elastic properties and resistance to mechanical damage, unlike PTFE which is a thermoplastic and generally lacks the necessary resilience to withstand mechanical shock in a process application such as this.
