Features Of Solvay Tecnoflon PL 958 FKM Elastomer

  1. High fluorine content (≈68 wt%) for exceptional resistance to aggressive chemicals and hydrocarbons.

  2. Optimized for low-temperature flexibility with a glass transition temperature (Tg) of approximately –18 °C.

  3. Excellent compression set resistance after prolonged exposure to elevated temperatures up to 200 °C.

  4. Good processability in standard rubber compounding and molding equipment, including injection and transfer molding.

  5. Halogen-free formulation compatible with stringent environmental and regulatory requirements (e.g., REACH, RoHS).

Typical Applications Of Solvay Tecnoflon PL 958 FKM Elastomer

  1. Aerospace fuel system seals and diaphragms exposed to jet fuels and synthetic lubricants.

  2. Automotive turbocharger hoses and valve stem seals operating under high-temperature exhaust conditions.

  3. Chemical processing gaskets and O-rings handling concentrated acids, solvents, and amine-based media.

  4. Oil & gas downhole elastomeric components requiring stability in sour gas (H₂S/CO₂) environments.

  5. Pharmaceutical and biotech single-use fluid path connectors demanding extractables control and autoclave compatibility.
