Products Gel Sheetsθ-Gel)

These highly durable silicone shock absorption sheets are the perfect combination of softness and strength. GEL Sheets are available in custom hardnesses and shapes. We also offer GEL Sheets adhered to other materials.

Characteristics
Alpha GEL’s softness allows for deflection required for shock absorption and vibration damping, providing excellent cushioning and vibration damping performance.
Alpha GEL is exceptionally durable and resistant to weather, ozone, UV radiation, and chemicals.
Alpha GEL shows very low compression, resulting in long-lasting, stable performance.
Alpha GEL performs reliably at temperatures between -40°C and 200°C.
Alpha GEL’s composition makes it harmless to the human body and to the environment, causing no allergies when touched, and emitting no harmful gases when burned.
Application Example
Alpha GEL protects internal components from shock and vibration.
Technical Information

[Rebound Resilience]
Alpha GEL is temperature-independent when compared with other comparable materials.

[Compression Set]
Even after prolonged compression, Alpha GEL returns to its original state.
