Sponge silicone rubber products are generally utilized in numerous modern applications as it has many essential characteristics that make it appropriate for a wide range of objectives. Suitably, silicone sponge rubber is quite adaptable to work in a wide variety of challenging situations, incorporating superior execution in a wide scope of temperatures. They additionally perform well in applications where sound and vibration separation is vital.
Silicone rubber is a simulated semi-natural product. The structure of silicone rubber comprises of a chain of silicon and oxygen atoms instead of carbon and hydrogen molecules, as compared with different sorts of rubber. The atomic structure of silicone rubber makes it a truly adaptable, however a delicate chain.
Sponge silicone rubber cord, silicone foam tubes, sponge extrusion profiles, sheets are produced using gum-based Polydimethylsiloxane (PMDS). During the heat curing process, the expansion of the silicone rubber creates closed cell sponge shape. To understand it effectively, it can very well be contrasted with adding yeast to bread so that it rises, thus making cushioned air cavities. Expanded closed cell silicone sponge materials offer an enormous number of execution advantages of strong silicone in a milder and progressively manageable structure.
It is significant when picking any type of silicone sponge to comprehend the distinction between open and closed cell. Puzzling the two can cause disappointment of a seal or gasket in the application.
Open Cell Sponge Silicone Rubber
Open cell fundamentally implies that every cell, or an air pocket, is broadly associated with the following cell. These cells are not finished terminations, in this way, water, dampness, and residue can advance into the cell structure.
A certifiable instance of an open cell sponge is the kind of sponge that is used to wash general household items. In the event that you place the wipe in a basin of water, you see the wipe dousing up heaps of water which is then pressed out again onto the vehicle. The water is permitted to go through every cell and along these lines gets retained and held inside the sponge.
Closed Cell Sponge Silicone Rubber
Closed cell sponge has a vastly different cell structure to open cell. In a closed cell silicone sponge, each cell carries air in a finished and closed pocket. Water, humidity, and other deposits cannot enter any of the cells. For any kind of sealing purposes, closed cell sponge is extremely good for use as it has extremely low water ingestion keeps the water or any other fluid/material totally isolated.
The essential contrast between an open cell and closed cell sponge is the toughness and pressure rate. Closed cell sponge will be significantly firmer. With an open cell sponge, the air can get away when pressed and the main defiance is from the rubber itself.
Silicone sponge material applications
- General Sealing in different Industries/Custom Gasket Applications
- Outdoor Gasket
- Sound and Vibration Insulation
- Hot & Cold Thermal Insulation
- Water Sealing
- Cushioning
- Insulating/Lighting Fixture Gasket/Electrical Enclosure
- Flame Retardant Sponge
- Food Processing Machinery Seal/Pharmaceutical Equipment
- Oven Seals
Numerous different variables can impact the silicone sponge extrusion procedure, for example, surrounding temperature, humidity, air flows around the extruder, and plant voltage fluctuations, among others.
Silicone sponge material benefits
- Highly effective sealing capabilities
- Excellent Ozone and UV resistance
- Can be specified in low, medium or high-density firmness
- Controlled compression and recovery characteristics
- Shock absorption attributes
- Multiple materials can be used at the same time
- Design flexibility
- Can be used to produce very small parts.
Silicone Sponge Rubber help to reduce vibration and high-volume noises from passing through. This type of Silicone Rubber has excellent thermal properties and is incredibly flexible. Silicone Sponge Rubber is suitable for mass transit applications, sealing, thermal insulation, and gasket. The flexibility of Silicone Sponge Rubber means that it can be modified easily and responds well to a variety of circumstances.
