Calendered Silicone Sheeting
Calendered or extruded sheets of solid or sponge VMQ silicone. Thicknesses from 0.3 to 10 mm and widths up to 1,200 mm. Compliance with FDA, EC 1935/2004, UL94, EN 45545-2, USP VI, and ISO 10993. Delivered in rolls, spools, or custom-cut formats.
Process Principle
Silicone sheeting is obtained by calendering or continuous extrusion, offering uniform thickness and excellent thermal stability. It is suitable for the manufacturing of gaskets, seals, or technical linings across various sectors.
Materials and Formulations
Available in solid or cellular (sponge) VMQ silicone with hardnesses from 10 to 80 Shore A. Certified formulations: food-grade, medical-grade, fire-retardant, antistatic, conductive, high-temperature, or fluorinated (FVMQ). Compliant with FDA, EC 1935/2004, EN 45545-2, UL94, USP VI, and ISO 10993.
Dimensions and Finishes
Thicknesses from 0.3 to 10 mm, widths up to 1,200 mm, and lengths from 5 to 25 m. Smooth, textured surfaces, or with 3M technical adhesive. Standard colors (translucent, white, black, grey, red) or custom RAL colors.
Production Environments
Manufacturing in an industrial environment for large volumes or an ISO 8 cleanroom for medical and food sectors. Processes under ISO 9001 and ISO 13485 with continuous traceability and dimensional control.
