Product catalog summary
Environmental Sealing Silicone Overview
Getelec offers fluorosilicone and silicone products designed for environmental sealing applications. These elastomers are suitable for manufacturing molded items, extruded seals, cut flash seals, and seals vulcanized in place. They maintain mechanical properties across a wide temperature range.

Fluorosilicone Products (FVMQ)
- Working Temperature: -60°C to +230°C
- Resistance: Good resistance to solvents, fuels, organic and silicone oils.
- Applications: Molded items, extruded seals, cut flash, and vulcanized seals.
- Measurements: Conducted on molded sheet material and cut sections.
- Tolerances: Specific tolerances apply unless otherwise specified by FAI, DVI, or control documents.

Silicone Products (VMQ)
- Working Temperature: -70°C to +232°C
- Applications: Similar to fluorosilicone, with additional options for fire-resistant versions (UL 94) and various cutting methods (tool, laser, water jet, flash).
- Thickness: Available up to 10 mm upon request.

Product Specifications
- Standards: GT 20 to GT 80, with varying elastomer binders (silicone or fluorosilicone).
- Hardness: Shore A (±5) ranging from 25 to 80 (ASTM D 2240).
- Specific Mass: Measured at 25°C, ranging from 1.10 to 1.48 g/cm³ (ASTM D 792).
- Tensile Strength: Ranges from 870 psi (6 Mpa) to 1250 psi (8.60 Mpa) (ASTM D 412).
- Elongation: Varies from 165% to 950% (ASTM D 412).
- Residual Deformation: After 22 hours at 177°C, ranges from 20% to 35% (ASTM D 395 Method B).
- Color Options: Red, White, Blue, Orange.

Sheet Sizes and Tolerances
- 300mm x 300mm Sheets: Thickness tolerances range from ±0.07 mm to ±13% depending on thickness.
- 150mm x 150mm Sheets: Tolerances range from +0.05/-0 mm to ±13% depending on thickness.

Available Formats
- Molded, Cut Sheet, Extruded, Vulcanization.
