Extensive patent portfolio

SiO2 Materials Science is a leading manufacturer of advanced polymer containers with customized coatings and surface treatments.


SiO2’s technology can be found in its manufactured products and in certain products offered by SiO2’s customers.  The SiO2 technology platform uses a modified plasma enhanced chemical vapor deposition (PEVCD) process to apply multiple layers of a barrier coating to any polymer / plastic substrate. The layers combined are less than 500 nanometers – or 100 times thinner than a human hair and provide a highly effective barrier to environmental gases and leachates.


The SiO2 technology platform is protected with more than 300 patent entities covering close to 8000 patent use claims.

SiO2 patent portfolio covers:

• Hybrid material
• Barrier coating & processes
• Inspection methods & solutions
• Quality control processes
• Primary containers & molding processes
• Molecular biology preservation
