Service

Thermiculite® 896 material has found usage where a robust product is required with small land-widths.

  • Conformable
  • Resilient
  • Suitable for high temperature applications
  • Excellent gas and liquid sealing characteristics
  • Good stress retention
  • Excellent low load sealing characteristics
  • Suitable for use in high temperature low stress sealing applications
  • Chemically resistant
  • Very low halogen content coupled with a sulphur free curing system gives excellent resistance to stress corrosion
  • Suitable for seawater service or marine environments. This contrasts with products based on exfoliated graphite where
    galvanic corrosion can occur
  • Not susceptible to thermal oxidation
