We have developed a proprietary epoxy molding system. The system is designed to run very fast molding cycles with excellent shelf stability. Also, this system requires low transfer pressures for optimum fill properties. The material is mineral filled and fiber re-enforced and will meet a UL 94 V-O flammability. Being of this system exhibits excellent moisture protection and lead adhesion.
Vpoxy a revolutionary epoxy molding system designed to run very fast molding cycles with excellent shelf stability. Also, this system requires low transfer pressures for optimum fill properties. The material is mineral filled and fiber re-enforced and will meet a UL 94 flammability. Being of this system exhibits excellent moisture protection and lead adhesion.
Vpoxy is a soft flow mineral filled fiberglass reinforced epoxy molding compound. This material was designed to be molded in both transfer and screw injection molding equipment. Vpoxy exhibits exceptional shelf stability while still being rapid cure. Additionally, Vpoxy is considerably less abrasive than ordinary silica filled materials.
