What Is the Difference between Sponge Rubber and Rubber Foam?

 It is difficult for the average consumer to tell the difference between sponge rubber and foam rubber. This is because the two terms are often used interchangeably, but their applications are very different considering their molecular structure and benefits to the user. Rubber foam supplier has broken down the differences between them, common applications and industries to help in the decision-making process when choosing the right material for your project.

Rubber foam

Rubber foam is an inflatable structure, usually made of polyurethane or latex (PVC). Because its compartments are structurally rigid, it excels at being a sound and/or physical impact damper. This is why one of its main uses is in the manufacture of mattresses, as foam rubber is known for its durability, ageing resistance and longevity. It is also lightweight, has excellent cushioning properties and is buoyant.

Other common applications are glass protection and transport mats, sun visors, equipment gaskets and gaskets, and dust seals for domestic use.


Sponge rubber

There are two main types of sponge rubber, commonly referred to as closed-cell and open-cell, and are most commonly made from polyethylene foam.

Closed-cell

Closed-cell sponge rubber does not allow water, air, dust and other chemicals to pass through its closed, airtight pockets. It has excellent UV resistance and, because of its closed-cell properties, is ideal for outdoor applications in both hot and cold environments. It is also very durable, which means that it ages well and does not degrade over time.

Due to its low absorption properties, closed cell sponge rubber is ideal for applications where maintaining structural integrity is critical, such as in fenders and buoyancy aids in the marine and floating body industries.

Rubber Foam

Sponge 

It is both an insulator and a material that prevents water absorption, and it is very effective as a gap filler. Not to mention its ability in noise and vibration attenuation and its use in cushioning. Closed-cell polyethylene is often used for aircraft seats in the aviation and aerospace industries due to its durability, comfort and lightweight properties.

Polyethylene

Sponge rubber or foam is more commonly used in our everyday applications as consumers. Open pores have open, interconnected pockets that allow water, air and other chemicals to pass through when the foam rubber is not compressed. This means that open-cell sponge rubber is often used in applications where such elements need to be absorbed.

Open-cell sponge rubber absorbs liquids and then traps them until they are compressed. Consider it for use in general-purpose sponges, sponge cloths, kitchen towels, foundation applicators, water filtration and more.

However, this is not the only use, as open-cell sponges are also particularly suitable for sealing and cushioning between uneven and irregular depths. The material is extremely soft, very supple, durable, UV and weather-resistant and have excellent thermal properties in both hot and cold temperatures.

When compressed open-cell sponge rubber provides an airtight seal, it can also be laminated to form a tape for complex gap filling.


Open-cell

Open-cell sponge rubber is used as a replacement in many industries such as construction and building, aerospace and aviation, packaging and protection, automotive and transport, beauty and healthcare and glass and glazing.

Advantages of rubber foam

Meteryflex rubber foam insulation materials have used the equipment which introduced of foreign high-tech equipment, with the in-depth study, developing more superior performance rubber insulation materials. This product is no fibre dust, formaldehyde-free, without Chlorofluorocarbon ( CFC ) and other ozone-depleting substances, with smaller and more even cell, having a stronger tear strength and higher flexibility. Greater extent to improve the product's performance, and achieve better environmental protection energy-saving effect. These products are always green surface (also could customer design colours ) and smooth surface which is not easy to gather dust, no smell, healthier environment.

Introduction to Glass Wool(Part 2)

  The sound absorption performance of centrifugal   glass wool  is also closely related to the installation conditions. When there is an air layer behind the glass wool board, the sound absorption effect is similar to that of a glass wool board with the same thickness without an air layer. In particular, the sound absorption performance of medium and low frequency will be greatly improved than the material is attached to the hard bottom surface. The sound absorption coefficient will increase with the increase of the thickness of the air layer, but the effect will not be obvious after increasing to a certain value. Using glass wool of different bulk density is stacked together to form a form of gradually increasing bulk density, which can obtain a greater sound absorption effect. For example, stacking a 2.5cm thick 24kg/m3 cotton board with a 2.5cm thick 32kg/m3 cotton board will have better sound absorption than a 5cm thick 32kg/m3 cotton board. The 24kg/m3 glass wool boa...

Application Field of Extruded Board

The extruded board is a high-quality and cheap construction insulation material in the construction industry. It can not only be used as wall insulation but also has an excellent performance in other aspects. The following  extruded board manufacturers  will tell you what are the application areas of extruded boards? 1. The extruded board can be used as floor installation auxiliary material The floor mat used in the floor mats installed in the suspended floor is extruded board. Its paving is very convenient and can prevent the floor from being damp, deformed, and moth-eaten. The sound insulation and heat preservation effects are also very obvious, and you can feel a little softness when you step on the floor, which is very comfortable. Using this kind of extruded board mat to pave the floor can protect the ground from damage. It can be used when installing composite flooring, solid wood multilayer flooring, and solid wood paint-free and planer-free flooring. 2. Make a...

Demand For Glass Wool In The Market

Glass Wool  has good molding, low thermal conductivity, thermal insulation, and good attraction. It is widely used in building insulation. It is used for thermal insulation, sound absorption and noise reduction of industrial buildings, warehouses, public facilities, exhibition centers, shopping malls, and various indoor playgrounds, sports venues and other buildings. Glass Wool Glass wool insulation materials are also very helpful for building energy saving. With statistics, glass wool can achieve energy saving rate of 55%. Glass wool is based on the principles of vacuum insulation and microporous insulation. Using glass fiber as the core material, the thermal conductivity can reach 0.036W / (mK) or less. The thermal insulation performance is 6 to 10 times that of traditional thermal insulation materials. Products from raw materials collection to the entire production process are combined with environmental protection requirements, non-toxic and harmless; not only can ...
