Transforming Waste Tires into High-Value Silicone Products

Neopara is helping to make silicones greener


We produce a patent-pending 'reinforcing filler', an ingredient for silicone products, made from waste tires.


Adding our product as a reinforcing filler can both reduce the carbon footprint and lower the cost of silicone products.

Extensive applications in the $9B construction silicone industry, in sealants, coatings, and adhesives

Diverts waste

Diverts used tires from landfills and other low value uses

Similar performance

Meets the same performance specifications as pure silicone

Reduced footprint

For every kg of silicone displaced, ~16kg of CO2e emissions are avoided

Cost Competitive

The process converts low-cost inputs to high-value final products

Incredible traction

Adds traction for safety and serviceability in roofing applications

Transforming waste tires into high-performance silicone products

Neopara buys (widely available) ground up used tires

We chemically modify the tire rubber to bond well with silicone

We sell the modified rubber to silicone formulators

Formulators add our product to silicone formulations, decreasing footprint and cost

Extensive testing completed with silicone sealants and roofing products
