Rubber and plastic insulation materialsIt is a high-efficiency and energy-saving insulation material, with excellent thermal insulation performance and fire performance. According to the different requirements and specifications of use, rubber and plastic insulation materials can be divided into different grades, among which the common ones are B1 and B2. There are some differences in their performance and use, so how to distinguish B1 and B2 rubber and plastic insulation boards?
1.Appearance:The appearance of B1 grade and B2 grade rubber and plastic insulation materials is basically the same, both are closed-cell structure insulation materials, with smooth and shiny surfaces. However, the surface texture of B1 grade insulation is more uniform and feels better.
2.Density:The density of B1 and B2 rubber and plastic insulation materials is different. Generally speaking, B1 grade insulation board has a higher density and a more compact texture, while B2 grade insulation material has a lower density and a relatively loose texture.
3.Resilient Recovery:There are also differences in the elastic recovery of B1 and B2 rubber and plastic insulation materials. B1 grade insulation material has better elastic recovery performance and can better adapt to deformation and bending, while B2 grade insulation material has poor elastic recovery performance.
4.Environmental performance:Rubber and plastic insulation material B1 is an environmentally friendly and non-toxic product, in line with national environmental protection standards, while rubber and plastic insulation material B2 grade environmental protection performance is relatively poor.
5.Combustion performance:Rubber and plastic insulation material B1 is a flame retardant product, with the addition of flame retardant, flame retardant can effectively prevent the spread of flames, so B1 grade insulation materials have better flame retardant performance and can effectively prevent the spread of flames. However, the rubber and plastic insulation material B2 does not add flame retardants, and the flame retardant performance is poor, so it cannot prevent the spread of flames.
Rubber and plastic insulation B1 grade ** is relatively high, while B2 grade ** is relatively cheap.
7.Usage:
B1 grade rubber and plastic insulation materialIt is a high-grade insulation material with excellent performance and a wide range of applications. It is mainly used in occasions with high fire protection requirements, such as the exterior walls, roofs, floors of buildings, etc. In addition, B1 grade insulation materials can also be used for thermal insulation in refrigeration, air conditioning, plumbing and other fields.
B2 grade rubber and plastic insulation materialIt is an economical thermal insulation material, which is widely used for thermal insulation of general buildings. It can be used on the exterior walls, roofs, floors and other parts of buildings, as well as the pipes and equipment of air conditioning systems. Compared with B1 rubber and plastic insulation materials, B2 insulation materials are more affordable, so they are widely used in some occasions with low fire protection requirements.
To sum up, there are differences between B1 and B2 grades of rubber and plastic insulation materials in terms of appearance, density, elasticity, environmental performance, combustion performance and use. B1 grade insulation material has higher density, better elastic recovery performance and better flame retardant performance, so it is suitable for occasions with high fire protection requirements; The B2 grade rubber and plastic insulation material has a more affordable ** and is generally used for thermal insulation of general buildings. When choosing, you can choose according to your specific use and needs.
