FEATURES
- Superior thermal performance in molded electrical sheet
- Good corrosion resistance to non-oxidizing acids, organic acids, and corrosive salts
- Meets NEMA GPO 2 and GPO 3 standards as electrical sheet
APPLICATIONS
Hetron 92 resin can be used for flame retardant reinforced thermosetting plastic equipment and parts manufactured with the bulk molding compound and sheet molding compound processes or the pultrusion process. Hetron 92 resin can also be used as a halogen concentrate resin to blend with non-flame retardant resins.

Note: Hetron polyester resin will burn if provided with sufficient amount of heat and oxygen. The degree of flame retardancy of the cured polyester resin is characterized by the ASTM E-84 tunnel test. This test is performed under strictly controlled conditions where a flame spread rating is assigned according to comparisons with test set-point materials. The behavior of the cured composite under these controlled conditions can vary from an actual fire situation.
