How to Choose Rubber Insulation Materials and Glass Wool?

 In the insulation of air-conditioning ducts and the insulation of buildings, both rubber insulation cotton and glass wool can play a certain role in insulation, and both have similar performance. Because both have the advantages of energy-saving, convenient installation, labor cost-saving, and labor intensity reduction, they have good economic and social benefits and play an important role in creating an effective, energy-saving, comfortable and safe working environment and home environment.

Rubber Foam Insulation

1. Different appearance

Rubber and plastic insulation materials are made of effective foam, soft and tough. It occupies very little space during the installation process, so it occupies very little space after completion and looks very beautiful after installation. The glass wool has an open-pore structure and is a hard inorganic material. During the installation process, it will take up a lot of space, especially the height of the ceiling will be affected, and it is not easy to form after installation.

2. Different thermal conductivity

The initial thermal conductivity of rubber-plastic thermal insulation material is 0.035W/(m·k), and the initial thermal conductivity of glass wool is 0.038W/(m·k). The lower the λ value of the thermal conductivity, the better the thermal insulation effect of the material. Through comparison, it can be seen that the insulation performance of rubber and plastic insulation materials is significantly better than that of glass wool.

3. Different flame retardancy

The flame retardancy of rubber and plastic insulation materials is usually B1 or B2, and the flame retardancy of high-grade rubber and plastic insulation materials is B1 flame-retardant material. The material meets national standards and can effectively prevent fires. The flame retardancy of glass wool is Class A, and the flame retardancy and fire resistance are inferior compared with rubber and plastic insulation materials.

4. The construction progress is different

The density of rubber-plastic insulation material is higher than that of glass fiber, but rubber-plastic insulation material is relatively soft, which is more convenient and quick in actual construction and operation. In future use, it is not easily damaged and easy to repair. In the installation process, the glass wool needs three steps of cutting, bonding, and binding, which is not easy to operate.

5. Different economic performance

Rubber and plastic thermal insulation materials are usually used for the insulation treatment of air conditioners and buildings. Although the unit price is slightly higher, its auxiliary materials have low cost, low loss, long service life, and low annual cost. Glass wool is mainly used for sound absorption and sound insulation in large places such as stadiums and workshops, and its material unit price is slightly lower. However, due to poor waterproof performance, an additional fireproof layer is required.

The above information is provided by the rubber foam insulation factory.

Neoprene vs EPDM: What's the Difference?

  Both neoprene and   EPDM   are materials used in the manufacture of conveyor belt systems. While neoprene is most commonly used in the industry, many companies are turning to EPDM because using it overcomes many of the challenges associated with using neoprene.   What is neoprene? Neoprene is made through the polymerization of chlorine. Characterised by its chemical stability, flexibility over a wide range of temperatures and resistance to degradation, the material was originally intended as a petroleum-based alternative to natural rubber.   Its durability and flexibility make neoprene suitable for a wide range of everyday products - such as sports and medical equipment, technical coverings and sleeves, diving suits and safety gloves - as well as for a variety of outdoor applications - including as hoses, gaskets, seals, and gaskets. -including as hoses, gaskets, seals, coatings and linings.   Huamei  EPDM rubber foams  include semi-closed cell ...

Do You Know What the Use of Glass Wool Insulation Material Is?

  From the present day, we can see that   Glass Wool   insulation material is used in many aspects of daily life. Its thermal insulation properties make it widely used in daily life or work. The most common is that in colder winters, people can use this product to wrap their own water pipes. This can ensure that their water pipes are not frozen, and then the water between them can be kept flowing for as long as possible.  Glass Wool Because of its shearability, glass wool insulation materials can be trimmed according to their own needs, and products of different sizes can be cut and used in different places. For example, in this relatively cold place in the Northeast, people can wrap this product on their own roofs, make their houses adhere to a certain temperature, and fully play the role of heat insulation of this product, bringing comfort and comfort to their lives. convenient. In addition, glass wool insulation materials are also used more locally. With the exten...

What Aspects Does the Usability of Glass Wool Reflect?

  In the field of architecture, the quality of a building is directly related to its material design. Therefore, when choosing building materials, There are a lot of people who will also ask the glass wool practical reflected in what aspects? Always cannot say oneself spent big price to buy after a batch of vitreous cotton, connect its use sex to highlight in what respect all do not know, the loss that oneself suffer in that way is particularly much also. First of all, the sound insulation of  glass wool  is particularly good. For example, if you are decorating the boss’s office or the home, if its sound insulation is not good, it will affect everyone’s work and life, but it can be If you use glass wool, it can play a very good sound insulation effect, even if it is noisy outside, you still can't hear any noise, which can bring great convenience to life and work. Secondly, it can be cut at will, because when you buy a batch of glass wool, the size is not certain. When you...
