Gaskets made of Kalrez® perfluoroelastomer (FFKM/FFPM) are particularly ideal for extreme chemical and thermal stresses. Elasticity and recovery properties are maintained, and a durable sealing effect at continuous operating temperatures of up to approx. 300°C is guaranteed.

The proven consistent resistance of Kalrez® enables the production of long-lasting gaskets for higher productivity and sustainability.

The universal media resistance is comparable to that of Teflon® (PTFE), but with the properties of elastomers.

telle manufactures flat gaskets from sheet material according to sample, drawing or file. The individual production allows to produce application-specific gaskets directly for your requirements.

Advantages of Kalrez®
  • Resistant to aggressive media, such as chemicals, solvents and plasmas
  • High temperature resistance up to 300°C
  • Reduced operating and maintenance costs
  • Long service life of the gasket
  • Meets pharmaceutical and food processing safety standards
