What is the sound insulation effect of rubber and plastic insulation board? Today we are going to introduce the sound insulation function of rubber and plastic insulation board. Perhaps a lot of people will ask, by wrapping rubber insulation board can achieve the effect of heat preservation? Let's take a look!


Yutersen rubber and plastic foam insulation material is the introduction of the latest foreign technology and technology, the use of automated production lines, with excellent performance of nitrile rubber, PVC as the main raw materials, through refining, vulcanization foam and other special processes made.


The sound absorption performance of rubber and plastic insulation board will have a lot of direct relationship with the physical structure of the product itself. Because of its tightly foamed structure and elastic surface, the rubber insulation board has a good effect on reducing external sound. However, many environmental factors determine the sound isolation and reduction effect of rubber and plastic insulation board in the actual use of the process. For example, their thickness and density as well as the flow resistance of air have a great impact on sound insulation and noise reduction. Airflow resistance is usually the ratio of the air pressure on either side of the material per unit thickness to the air flow between the two sides. It will also affect the sound absorption efficiency of rubber - plastic insulation board. If the flow resistance is too small, it indicates that the structure of the whole material is very sparse. Noise in the process of air vibration is particularly easy to pass through this material, resulting in sound absorption and noise reduction performance will be reduced.


The main characteristics of Uetersen rubber and plastic insulation board are:


1, low density, closed bubble structure, thermal conductivity, water vapor permeability, low water absorption, rich softness, convenient construction;


2, wide temperature range, from -40℃ to 105℃ and good aging resistance, durable, flame retardant effect to reach the national B1 standard;


3, green environmental protection, from production to installation fully meet the national environmental protection requirements, the overall appearance is beautiful;


4, Based on the above characteristics, this product is widely used in central air conditioning refrigeration room, construction, ships, vehicles and other industries of all kinds of water, steam pipe insulation, heat insulation, and obtained the ideal use effect.
