What are the engineering sponge types and uses?

Engineering sponge is a versatile material that is extremely flexible for using in a variety of demanding environments. Generally, according to different uses, engineering sponges types can be divided into sound absorbing sponges, fire proofing sponges, heat insulation sponges, and thermal insulation sponges. Our technical team has put together a guide explaining the types of engineered sponges and the most common using industries.

1.The types and uses of sound absorbing sponges

There are two main types of sound absorbing sponges: open-cell sponge and base material flocking sponge. Open-cell sponge is full of a continuous pore structure to absorb sound waves, while base material flocking sponge improves sound absorption performance by covering the sponge with a layer of fluff. In terms of shape, there are so many types,such as flat plates, grooved plates, cones, egg-crate shapes (wavy bulges and depressions alternately) and pyramid shapes. Sound absorbing sponge has excellent sound-absorbing properties,which is related to its irregular surface structure.Its working principle is to absorb sound waves by increasing the surface area, effectively reducing sound reflection and reverberation, thereby improving sound quality.

Sound absorbing sponges primary usages include recording studios, home theaters, public speaking venues, and offices and classrooms, helping to create a more tranquil and focused environment. In industrial environments, sound absorbing sponges can also reduce noise generated by machinery operations and protect workers' hearing.

2.The types and uses of fire proofing sponges

Flame-retardant polyurethane sponge and flame-retardant polyester sponge are the main types of fireproof sponges. They are both specially processed foam materials with high flame-retardant properties, allowing them to self-extinguish or significantly slow down the spread of fire in the event of a fire.The shape of the fireproof sponge is not fixed and is mostly customized according to the usage scenario, because it is often used in various fireproof sealing and insulation situations. Common shapes include flat plate, strip, and cylinder.

In terms of uses scenarios, fire proofing sponges are widely used inside vehicles, such as seats in trains and cars. Its main functions are light weight, which can improve track energy efficiency and cornering stability. From the aspect of material, engineering sponges made of melamine resin is the best choice because it is the lightest plastic in the world.

3.The types and uses of heat & thermal insulation sponges

Common types of heat insulation sponges include polyurethane sponges and silicone rubber sponges.Thermal insulation sponge is a sponge with a closed cell structure made of polyurethane, silicone rubber foam and other materials, which can effectively reduce the heat transfer through the surface of the object. Heat insulation sponges can be processed into a variety of shapes such as flat sheets, tubes, strips, to suit application needs.

Heat insulation sponge is usually used for building insulation, such as hot water tanks, ventilation ducts of air conditioners, gas ducts, etc., to protect the ducts from temperature fluctuations and reduce heat energy loss; as well as for heat insulation of household appliances and car interiors. The application of this material increases energy efficiency and helps create a more comfortable living and working environment.

Thermal insulation sponges are similar in material and application to heat insulation sponges. They are both mainly used to ease the alternation of energy, improve energy efficiency, and reduce energy consumption.
