Our Mistrobond product is a very fine microlamellar talc that 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.

The Mistrobond range provides:

- Excellent barrier properties

- Good chemical resistance

- Improved modulus

- Low compression set

- Carbon black replacement

- Barrier properties

In tests conducted at our laboratory in France, medical stoppers reinforced with our Mistrobond talc demonstrated 30% less permeability than stoppers filled with calcined clay, for example. Mistrobond talc also improves tear resistance of stoppers, limiting fragmentation.

Mistrobond talc is available in compacted form for easy handling and high processing throughput.

Key benefits:

- Excellent barrier properties

- Good chemical resistance

- Improved modulus

- Low compression set

- Carbon black replacement
