Extruded Square Silicone Profiles
Extruded VMQ silicone square profiles with ISO 3302-1 E1 tolerances. Hardness 10-90 Shore A. Compliance with FDA 21 CFR 177.2600, EC 1935/2004, UL94, EN 45545-2, USP VI, and ISO 10993. Industrial or ISO 8 cleanroom production under ISO 9001 and ISO 13485 control.
Process Principle
Square silicone profiles are manufactured by continuous extrusion and controlled thermal curing. They are ideal for linear sealing, dampening, and insulation in industrial, food-grade, or medical applications.
Materials and Formulations
Made from solid VMQ silicone with hardnesses from 10 to 90 Shore A. Available formulations: food-grade, medical-grade, fire-retardant, antistatic, high-temperature, or fluorinated (FVMQ). Compliant with FDA, EC 1935/2004, UL94, EN 45545-2, USP VI, and ISO 10993.
Dimensions and Finishes
Square profiles from 2×2 mm up to 50×50 mm. Tolerances according to ISO 3302-1 E1. Smooth, satin, or textured finish. Standard colors (translucent, white, black, grey, red) or custom RAL colors.
Production Environments
Production in an industrial environment or ISO 8 cleanroom. Processes certified ISO 9001 and ISO 13485 with dimensional control, batch traceability, and hardness/tensile testing.
