Bio Soluble Felt

A recent addition to our fiber product range is a breakthrough in insulation technology. This high-temperature insulation has a high solubility in simulated bodily fluids and therefore has no hazard classification.

Manufactured in an advanced process specially developed for these high-quality bio-soluble fibers, Bio Soluble Felt is available in various sheet thicknesses up to 100mm.

The plates can be easily cut with standard tools and punching machines.

The small amount of binder has the advantage of keeping dust to a minimum.

Tralcon Bio Soluble Felt possesses the following exceptional characteristics:

  • High-temperature stability
  • Easy to cut and shape
  • Lightweight
  • Excellent flexibility

* Classification temperature is not a measuring point of the operational limit of these products, especially when long-term physical or dimensional stability is a factor. For such applications, operational limits are generally significantly reduced. Please contact Tralcon for advice on these cases.
