Why spongy silicone sheet?
Spongy silicone (silicone foam) is the ideal material for industries that demand superior durability, flexibility, and stable long-term performance.
It provides outstanding waterproof protection thanks to its closed-cell structure and low water absorption, effectively repelling moisture and ensuring dependable sealing in harsh operating environments.
It also performs exceptionally well across extreme temperatures, ranging from -60°C to +250°C (-76°F ~ 482°F) (and even up to 315℃ / 600℉ for high-heat grades), while maintaining its elasticity and sealing properties through frequent thermal cycling.
In addition, spongy silicone offers excellent resistance to solvents, oils, and UV radiation, slowing material degradation and supporting long service life in outdoor and industrial installations. With low compression set, it maintains consistent compression over time, delivering a tight, durable, and leak-proof performance for years of reliable use.
