Product Overview
SENMA Open Cell Silicone Sponge is a soft, lightweight and flexible silicone sponge material designed for applications that require cushioning, air permeability, heat resistance and repeated compression.
Its fine open-cell structure provides excellent breathability, elasticity and compression recovery, making it particularly suitable for ironing tables, heat press machines, textile equipment and other continuous-contact applications.
Compared with conventional solid silicone sheets, open cell silicone sponge offers a softer and more conformable surface while maintaining the temperature resistance and long-term durability of silicone rubber.
The sponge can be supplied in different thicknesses, widths, colors and custom die-cut shapes to meet specific equipment and production requirements.
Key Features
Open Cell Structure
 |
 |
The fine open-cell structure allows air to pass through the material while providing a soft and resilient cushioning layer.
Soft & Flexible
With a standard hardness of approximately Shore A 10, the material is suitable for applications requiring a soft and conformable surface.
Excellent Compression Recovery
The silicone sponge can withstand repeated compression and recover its original shape, making it suitable for continuous pressing and contact applications.
High Temperature Resistance
Designed for demanding thermal environments, the material can be used across a wide temperature range of approximately -60°C to +250°C, depending on the specific formulation and application.
Lightweight Construction
With a reference density of approximately 0.13 g/cm³, the sponge provides cushioning and surface protection without adding significant weight.
Cushioning & Shock Absorption
The soft sponge structure helps absorb mechanical impact, reduce vibration and protect contacting surfaces.
Aging & Weather Resistance
Silicone provides good resistance to aging and maintains flexibility during long-term use under suitable operating conditions.
Fully Customizable
Thickness, width, length, color and die-cut shape can be customized according to equipment design and application requirements.
