BLW Dry Liquids Prisma Rubber Additives

Silane-Modified Silicas


Prisma Rubber Additives’ new range of ‘Adsil’ silane-modified silica grades are designed to react with a wide variety of organic and inorganic materials. They are used as coupling agents, crosslinking agents, and surface modifiers which enable them to be used in a wide range of applications such as tires, adhesives and surface coatings.

Especially in Elastomer compounds, ‘Adsil’ grades can be used as reinforcing fillers in compound design and formulation. They are used in a wide range of polymers such as NR, IR, SBR, BR, NBR, EPDM, EPM and blends thereof.

The ‘Adsil’ grades are widely used to produce mechanical rubber goods, and to improve the processability and production of finished articles.

‘Silane Molecule’

The advantages of the ‘Adsil’ grades:


  • Reaction in presence of accelerators by forming rubber to-filler bonds during vulcanization

  • Achieving tear and abrasion resistance on a high level

  • Excellent dynamic properties 

  • Shorter mixing cycles and less processing effort than using conventional silica

  • Less mechanical degradation of polymers.
