Household Air Purification Hot Melt Adhesive

         What are the applications of Hot Melt Adhesive in automotive filters?

In the daily use of automobiles, the filter products we are familiar with are generally divided into two categories: air filters and oil filters. Adhesives are often used in these two types of filter products, and the main function is to solve the process needs of the filter in the manufacturing process of bonding, shaping, sealing and so on. Binding Agent is widely used in the filter manufacturing industry because of its environmental protection, safety, temperature resistance, fast curing speed, high production efficiency and simple gluing operation. According to the use of the filter and its performance requirements, the application requirements of Hot Melt adhesive are also significantly different. For hot melt adhesives whose main components are mixtures of solids such as ethylene-vinyl acetate copolymer EVA, or polyolefin PO, there are insufficient oil resistance, water resistance, and limited tolerance to extremely harsh environments, such as high temperatures exceeding 150 ° C, or low temperatures exceeding -20 ° C. At present, filter manufacturers on the market for the inherent special use environment of oil filter products, with oil resistance, water resistance and tolerance to extremely harsh environments, generally use polyamide PA class hot melt adhesive.

We understand that the filter manufacturer has a special production of air filters, there are also air filters and oil filters produced at the same time, next we talk about the application of hot melt adhesive on the air filter products.

Air filters are mainly used for air filtration of air conditioning products, which can be divided into two categories of automotive air conditioning filters and factory room air conditioning filters. No matter what type, because it is the use of specific fiber paper to achieve the air filtration function, so the purpose of applying hot melt adhesive on the air filter products is roughly the hem shape of the filter paper, the adhesion of the filter frame and the filter paper, the border filling and sealing.

The Feature Hot Melt Adhesive For Filter:

With conventional tolerance: usually supporting the application of air conditioning filter products, in high temperature: general requirements of high temperature resistance, there are special requirements to reach 110℃ high temperature pass the test; In terms of low temperature: it is required to meet the preservation safety of the environment below -20℃.

Opening time: According to the individual manufacturers of existing air conditioning filter manufacturers on the market, due to advanced Equipment and high production line speed, shorter opening time will be proposed for hot melt adhesive.
Color: With the improvement of quality and product matching requirements of air conditioning filter manufacturers, they will put forward color requirements for hot melt adhesives, and generally choose two kinds of white and yellow.
