A dry, thermosetting polyester molding compound is touted as a replacement for phenolic resins by Mitsubishi Gas Chemical America Inc. of New York.
Vyloglass is a thermosetting resin featuring creep resistance at high temperature, according to Mitsubishi. Other advantages are moldability, and good mechanical and electrical properties. Mitsubishi is introducing Vyloglass to North America after its release many years ago in Asia. One application exploiting Vyloglass properties is an electrical brush holder for a dynamic motor.
The new dry-type polyester outperforms conventional thermoplastic molding compounds such as polyphenylene sulfide and polybutylene terephthalate in heat resistance and electrical properties, claims Mitsubishi. Vyloglass also boasts handling efficiency, storage stability and non-halogen based flame resistance.
Mitsubishi offers three grades of Vyloglass that vary in heat resistance and flame retardance.
