Mistron® CB For lower permeability, improved modulus and compression set in medical stoppers, O-rings and gaskets
Mistron® CB has been specifically designed to improve the barrier properties of stoppers, gaskets and membrane applications.
Mistron® CB is very fine microlamellar talc which has been surface treated with a proprietary silane coupling agent for use in sulfur and peroxide cured rubber compounds to improve barrier properties, modulus and compression set.
Mistron® CB provides:
- Excellent barrier properties
- Good chemical resistance
- Improved modulus
- Low compression set
- Carbon black replacement
In tests conducted at our laboratory in France, medical stoppers reinforced with Mistron® CB demonstrated 30% less permeability than stoppers filled with calcined clay, for example.
Mistron® CB also improves tear resistance of stoppers limiting fragmentation.
