Rubber sponge is a type of elastomeric material made from synthetic rubber or natural rubber which is processed with special technology to produce a material with a porous and soft texture. Rubber sponge is often used as a coating or filler material in various products, such as footwear, sandals, seat cushions, mouse pads, to applications in the automotive and electronics industries. The main property of the rubber sponge is its good elasticity, so it can be easily compressed and returns to its original shape after the load is released. In addition, its porosity allows the rubber sponge to absorb shock and vibration, making it suitable for use as a protective material for electronic products and machines. Rubber sponge is also resistant to various environmental conditions such as water, heat and air which makes it usable in various applications.
The following are some types of rubber sponges that are commonly used: EPDM rubber sponge: this type of rubber sponge is resistant to UV rays, extreme weather and chemicals. Due to its durable nature, EPDM rubber sponge is widely used in outdoor applications, such as in protective rubber on electrical equipment or pipes. Neoprene rubber sponge: this type of rubber sponge is resistant to oil and chemicals, so it is often used in industrial applications, such as in bearings and engine guards. Silicone rubber sponge: this type of rubber sponge has very high temperature and oxidation resistance properties. Due to its temperature resistance, silicone rubber sponge is often used in industrial applications such as rubber insulators in electrical machinery and equipment. Nitrile rubber sponge: this type of rubber sponge is resistant to oil and chemicals, so it is often used in industrial applications, such as bearings and engine protectors which are often exposed to liquids. PVC rubber sponge: this type of rubber sponge has lighter and more flexible properties compared to other types of rubber sponges. Because of its lightness and flexibility, PVC rubber sponge is often used in applications in products such as footwear, slippers and mouse pads. There are many other types of rubber sponges, depending on the properties and characteristics required for the application.
