Precipitated Silica for Industrial Rubber Applications
PPG introduced precipitated silica as an alternative reinforcing filler for carbon
black in tires in the 1930s. Since that time, the development of our reinforcing
silica products has been inextricably bound to on-going advancements in global rubber
compounding and manufacturing.
Today, we produce reinforcing synthetic amorphous precipitated silica products in
powder, pellet, granular and micro-granular form for use in rubber manufacturing.
Formulated in a variety of particle sizes and surface areas, these highly specialized products are engineered to increase the strength and durability of rubber for countless applications ranging from engine mounts, belts and hoses in automobiles, to wire and cable coatings, conveyor belts, printer rolls, syringe toppers, gaskets, seals, roofing systems, rubber gym floors and more.

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
