Microporous Precipitated Silica for Battery Separator and Synthetic Paper Applications
The microporous structure of precipitated silica makes it uncommonly well-suited to two highly specialized applications for which PPG is known as an industry pioneer.
Synthetic Papers
Precipitated silica is used in the production of PPG TESLIN® substrate, a proprietary synthetic paper by PPG, that excels for applications demanding a tough, high-performance material. The microporous structure of precipitated silica is combined with the strength of a polyolefin polymer to create a ruggedly durable synthetic substrate that locks inks, toners, adhesives, coatings, and laminating films into its structure, creating virtually indestructible bonds and related performance benefits that other synthetic papers cannot replicate
Battery Separators
Precipitated silica is a key component of battery separators used in lead-acid batteries for automotive, industrial, and recreational applications. The battery separator is a silica-filled polyolefin material, typically polyethylene, that prevents contact between the anode and cathode electrodes in the electrolytic bath while at the same time allowing charge transfer. Precipitated silica enables microporous battery separators with good electrolyte wettability and low electrical resistance, which are critical to battery performance.
Rubber
PPG's precipitated silica products have been integral to the rubber industry since the 1930s and have earned the trust of manufacturers and compounders around the world for their reliable performance, consistent quality and dependable supply.
Carrier and Free-Flow
Our precipitated silica products are used as free-flow and carrying agents for food, animal feed and agricultural and industrial applications enabling products and processes to flow better.
Coatings, Adhesives and Sealants
Our precipitated silica products are used as high-performance flatting agents, thickening agents and anti-corrosion pigments to improve the performance, workability and sustainability of coatings, paints, inks, adhesives, and sealants.
