PPG AGILON®, HI-SIL® and SILENE™ Silica Products
We offer a full a range of industry-leading silica products. Together, they are designed to provide manufacturers with optimized processing characteristics – such as faster cure rates, easier mixing, better flow, or more flexible extrusion and color compounding capabilities – while imparting specific properties to finished high-performance rubber products, including:
- Increased stiffness and reinforcing strength
- Enhanced resistance to heat build-up and abrasion
- Better tear and tensile strength
- Improved color retention and/or translucence
- Superior chip and chunk resistance

Agilon Performance Silica Products
Agilon performance silica is a patented material that is engineered to enhance the benefits of traditional precipitated silica by managing heat build-up and improving tensile strength while lowering viscosity at processing temperature.Based on a proprietary technology platform developed by PPG, Agilon performance silica also helps the rubber industry address the productivity and environmental challenges associated with in-situ silica/silane mixing. By enabling a simpler, more efficient mixing process, this revolutionary material reduces manufacturing complexity and capital investment by:
- Allowing the use of older mixing technologies
- Increasing mixing throughput
- Reducing energy consumption
- Eliminating almost all alcohol-related VOC emissions resulting from conventional silica/silane mixing
- Elimination of porosity-related extrusion inefficiencies
- Extended shelf life for uncured rubber
- Improved coupling in natural rubber applications
- Lower temperature mixing to avoid natural rubber degradation
