Seal Engineering Materials

 Material Blends

TexPoly converts high-performance polymer materials into seal and wear products
resolving customer application service condition requirements. Seal engineering materials utilized for
customer applications take into account the processing methods, types of fillers,
modifier content, molecular weight, etc. used for polymer material selection relative
to application requirements. In-house quality inspection, material conformance
specifications, and certifications are documented and referenced per Quality
Assurance Manual as well as customer requirements. .
