Silopren™ LSR 2540 is a two‑component liquid silicone rubber developed for textile and glassfiber fabric coating applications.
Silopren™ LSR 2540 is a two‑component liquid silicone rubber (LSR) specifically developed for the coating of textiles and glassfiber fabrics. This grade is designed to deliver excellent thermal stability, flexibility at low temperatures, and long‑term durability under dynamic stress, making it well suited for demanding technical fabric applications. Silopren™ LSR 2540 combines low viscosity processing with excellent thermal stability, flexibility at low temperatures, resistance to ageing, ozone, and UV exposure, and reliable performance under dynamic stress. The cured elastomer is not readily combustible and provides stable dielectric behavior across a wide temperature range.
Density: 1.08 g/cm³
Shore A Hardness: 40
Tensile Strength: 6.5 N/mm²
Elongation at Break: 500%
Tear Strength: 25 N/mm
Primary Chemistry:
Liquid Silicone Rubber
Poor durability under dynamic stress, requiring frequent replacement or maintenance
Loss of flexibility at low temperatures, which can compromise coated fabric performance
Thermal instability during processing or end use
Premature ageing from UV and ozone exposure
Inconsistent coating application due to high material viscosity
Combustibility concerns, including melting or dripping under heat
Electrical insulation instability across temperature ranges
Coated textiles for protective suits
Conveyor belt fabric coatings
Glassfiber fabric sleeves
Coated fabrics for compensators
Tents and other technical fabric applications
