The special thing: The 3D-molecular structure and the particularly strong O-Si-O bond make PolypearlTM ME inert and provide special properties.
The hybrid structure of PolypearlTM ME combines the advantages of organic compounds (elasticity, haptics, compatibility with organic substances) with the advantages of inorganic compounds (extreme temperature and chemical resistance).
PolypearlTM ME micro-powder is free-flowing and can easily be incorporated into compounds, masterbatches, rubbers, paints and varnishes. It fulfils the requirements of the most important regulatory aspects and has food approval.
PolypearlTM ME provides excellent chemical and solvent resistance and a very high temperature stability. It has excellent optical properties such as defined light diffusion for translucent plastics.
Tight, controlled particle distribution provides excellent antiblocking properties in film and foils and also in coatings
Available particle sizes: 1 – 10 µm
