At the scientific level, rubber and silicone are both thermoset materials, meaning once the material is molded it is “set” and cannot be broken down to be molded again. This means a large volume of product (anywhere from tens of thousands to over a million units) can be created by heating the TPE blend and injecting it into a mold, where the TPEs cool and form the desired shape. Thermoplastic itself means “the ability to be reprocessed by heat.”

Our early and consistent approach focused on protecting the health and safety of our associates, families, customers and communities.
