How to distinguish between B1 rubber insulation materials and B2 rubber insulation materials?
In the market, there are many varieties of rubber and plastic insulation materials. Many fake and shoddy products hang sheep's heads and sell dog meat. They are labeled and become B1 brands. So, what if you distinguish between Level B1 rubber insulation material and Level B2 rubber insulation material? EVA rubber rubber rubber foam
There are three ways:
1, the appearance of the product. Insulation material
A good B1 rubber plastic product, each box or bag of packaging has a certificate label, label on the ordered column code, according to the sequence code can be called to the factory customer service to inquire about the true or false goods. After the packaging is opened, the surface of the plate or tube will also be printed with the "class B1" sign.
2, different parameters and test standards.
B1 rubber products meet international standards, such as Fulesi insulation materials, are flexible closed bubble insulation materials, meet international standards BS476 and GB 8624, use temperature -50-105 °C, non-flammable B1 level, oxygen index ≥ 40, The thermal conductivity coefficient ≤ 0.032 w/m.k, the vacuum water absorption rate ≤ 5 %, the wet resistance factor ≥ 10000, the smoke density level 47, and the density 40-80 kg/m3. The level B1 rubber brand on the market is difficult to achieve this parameter value, not to mention the level B2 rubber insulation material.
3, product price and quality aspects.
The international brand of B1 rubber insulation materials is generally around 2,500 per cubic meter, and the quality assurance period is more than 20 years. The domestic B1 brand is around 1200 per cubic meter, and the B2 price is less than 1,000 yuan per cubic meter.
4, brand influence distinction.
Internationally renowned brands such as Fulesi, Yaluofu, Kaimen, and Duken do not produce Class B2 rubber products. If there is such a product in the market, it means that it is 100 % false. Another example is the Forrest 820 glue, which is less than 200 yuan per can on the market, all of which are branded counterfeit products.
