What kinds of hot melt adhesives are suitable for filters?

Hot melt adhesives are widely used in filter products, and filters can be divided into two categories: air filters and oil filters. Hot melt adhesive plays the role of bonding, shaping and assembling in the manufacturing process of the filter, and because hot melt adhesive has environmental protection characteristics and fast curing characteristics, hot melt adhesive is widely used in the filter industry. , has a significant contribution to improving the environmental protection degree of the filter and the improvement of production efficiency. Different filter applications have different requirements for the characteristics and materials of the filter hot melt adhesive. Generally, the commonly used filter hot melt adhesives include EVA, polyolefin PO, polyamide PA, etc. For oil-resistant and high-temperature filtration The hot melt adhesive is basically made of PA material.

 

The air filter hot melt adhesive is mainly of EVA type. Common air filters can be divided into two categories: automotive air conditioner filters and room air conditioner filters. Automotive air conditioner filters are commonly known as pollen filters. The function of the car air conditioner filter is to filter the air entering the cabin from the outside to improve the cleanliness of the air. The general filter material refers to the impurities contained in the air, such as tiny particles, pollen, bacteria, industrial waste gas and The effect of the air conditioning filter is to prevent such substances from entering the air conditioning system to damage the air conditioning system, to provide a good air environment for the passengers in the car, to protect the health of the people in the car, and to prevent the glass from fogging. In the process, the hot melt adhesive is mainly used in three aspects: the folding and shaping of the filter paper, the bonding of the filter frame and the filter paper, the filling and sealing of the frame.
