OPEN CELL Silicone Foam Sponge


Silicone sponge, foam and silicone tapes are designed to withstand the most demanding aerospace, industrial and high temperature application.   We supply products with a wide variety of characteristics.  Sponge is a closed cell material used for gasketing, thermal shielding, press pads and to isolate vibration.  Foam is a low density, low compression set material designed to meet a variety of flame retardant and low smoke requirements.  All products can be supplied with pressure sensitive adhesives, in sheets and bulk rolls and custom die cut to your specifications.  Click on any picture below to learn more about our standard products..

Open Cell Silicone Foam for Ironing Table

5mm-Iron Red 7mm-Yellow 8mm-Green 10mm-Blue

Open Cell Silicone Foam
is extremely resilient, totally synthetic sponge which displays excellent resistance to heat, weathering, ozone and a wide range of chemicals. It is impervious to UV light, is non toxic, chemically inert and has excellent compressibility and recovery over a wide temperature range.

used on many kinds of machines such as steam pressing machine; ironing table; garment finishing machine and so on. It also can be used as cushion in many fields.

Closed Cell Silicone Sponge

5.0mm-Red Sponge 10mm-Sponge Roll New Technology Sponge 15mm Silicone Foam

Closed Cell Silicone Foam is usually 0.6~0.8g/cm3. Because it is made of pure silicone, thus it has excellent flexibility; long life-span and evenly foamed. It can endure high temperature and won’t break up easily. It is evenly foamed with micro bubble; the bubble is visible by magnifier. Generally, we offer any size according to your request for the purpose of reducing your cost.


Mainly used on heat transfer machine, heat pressing machine, electric instrument gasket seal gasket and so on. It can also be used as cushion in many fields.

Silicone Foam is manufactured from a low viscosity liquid silicone which is cast on a smooth liner and cured through inline ovens.  Silicone foam can be supplied as an open cell, closed cell or combination of both, open and closed cell material.

Silicone sponge, on the other hand, is mixed and calendered on a rubber mill then cured via inline ovens or stationary mold press. 

Silicone foam is typically lighter in density, compresses with less force and has a lower compression set than silicone sponge.  Both products have good sealing properties, however the sponge has higher tensile strength and the foam has better flame resistance. All materials can be supplied with high temp acrylic adhesive or in custom die cut configurations.  

Silicone Sponge or Silicone Foam? What is the Difference?

Silicone sponge is derived from a thin sheet of uncured silicone gum that is chemically blown or expanded while curing in a high temperature press or rotocure. Silicone sponge products are considered to be fully closed cell, meaning the cells are non-interconnecting, therefore they do not allow water to wick through. Silicone sponges are tougher and have better tear resistance than silicone foams. Silicone sponge often provides better water sealing in heavy wash-down applications as compared to silicone foam.

Silicone foams are lightweight products derived from liquid silicone ingredients that are cast onto a liner and cured in an oven. Low density silicone foams have open cell structure that may allow moisture to pass through the cell structure. Open cell silicone foam can be compressed to collapse the cells offering a water tight seal. In contrast, higher density silicone foam products will have a higher proportion of closed cells compared with medium or low density grades. As with all gaskets, with the proper deflection, a good long term weather seal can be achieved.
