Vulcanized Silicone Frame Gaskets
Silicone gaskets with closed geometry adapted for metallic or plastic frames. Vulcanized corners without breaking continuity. Hardness 10-90 Shore A. Compliance with FDA, EC 1935/2004, UL94, EN 45545-2, USP VI, and ISO 10993. Manufacturing under ISO 9001 and ISO 13485.
Process Principle
Vulcanized frame gaskets are manufactured by cutting extruded profiles or cords and vulcanizing their ends at the corners onto a metallic or plastic frame. This process ensures sealing continuity without fissures or weak points.
