Silicone Foam MF 1
By guaranteeing a performance degradation of no more than 10% over ten years,Alstone MF-1 seating materials reduce ergonomic hot spots and improve rider comfort. With a warranty of ten years (see complete warranty for details) to enforce this guarantee, Alstone MF-1 materials are a smart choice for seating applications. With consistent,lasting comfort resulting from lasting quality comes the need for fewer refurbishments.
What is Alstone Silicone Foam MF 1?
Silicone Rubber Foam blocks are produced by mixing the two liquid silicone compositions,
Part - A: Base Compound
Part - B: Cross-linker or curing agent.
Mixing of these two compositions leads to generation of hydrogen. While the two compositions cross-linked together to form a solid rubber, the mixture simultaneously expands due to hydrogen gas formation and produces small air bubbles with in the rubber which results into production of a cushioning foam material.
Alstone MF1 silicone is a lightweight cellular silicone foam cast into block form up to 8 inches thick This lightweight, high quality material is typically used in cushioning and sealing applications and features FST (flame, smoke, toxicity) resistance. and is most often used as cushioning in passenger rail car seating. MF1 silicone’s proven durability and fire resistance means reliable comfort, longevity and safety. Alstone MF1 is available in three firmness ranges, allowing engineers to optimize seat designs and maximize passenger comfort while reducing weight and size. MF1 Silicone foam comes in soft, medium, and firm in it's traditional white color and is targeted more toward general industrial applications.
