FAQ's

Closed cell sponge rubber refers to a type of sponge rubber with sealed, non-interconnecting cells. These cells are closed off from one another, preventing the passage of air, water, or other substances. It offers excellent sealing properties and is commonly used in applications requiring insulation, gaskets, and vibration dampening.

Silicone sponges find versatile applications in various industries. They are used for electrical enclosure seals, thermal insulation, gaskets, gap fillers, and as vibration dampeners. Their properties make them ideal for applications where flexibility, resistance to extreme temperatures, and sealing effectiveness are crucial.

The main distinction lies in the structure of the cells. Open cell silicone has interconnected cells, allowing air and fluids to pass through. Closed cell silicone, on the other hand, has sealed cells, making it impermeable to liquids and gases. Closed cell silicone is preferred for sealing applications.

Silicone sponge rubber is a flexible and compressible material made from silicone rubber. It is characterized by a network of closed cells, providing a combination of flexibility, resilience, and sealing capabilities. This material is widely used in manufacturing custom and standard size extruded rubber profiles / gaskets for various industrial applications.

Silicone sponges are easy to clean. All you need to do is rinse them with warm water and mild soap. For stubborn residues, you can use a gentle scrub brush. Make it dry before reuse.

The lifespan of a silicone sponge depends on usage and maintenance. With proper care, including regular cleaning and avoiding harsh chemicals, silicone sponges can last for an extended period, making them a durable choice.

Yes, silicone sponges, especially closed cell varieties, are inherently waterproof. The closed-cell structure prevents the absorption of water, making them effective for applications where water resistance is crucial.

Yes, silicone foam is typically a closed cell. This closed-cell structure contributes to its water-resistant and insulating properties, making it suitable for various sealing and insulation applications.

Yes, silicone sponges are highly effective in applications requiring sealing, insulation, and vibration dampening. Their unique properties, such as flexibility and resistance to extreme conditions, make them a reliable choice in various industries.

Closed cell medium density silicone sponge refers to a specific type of silicone sponge with a moderate level of density and a sealed cell structure. This type of silicone sponge is often used in applications where a balance between flexibility and compression resistance is required, providing reliable sealing solutions in industrial settings.
