Weiwang hot melt adhesive manufacturer teaches you to use the folding edge of air filter element

The air filter element generally includes automobile air filter element, air purifier filter element, diaphragm air filter element and high-efficiency air filter element without diaphragm. The sizing function of hot melt adhesive is folding bonding, and the bonding material is glass fiber. It is required to be able to adhere to the glass fiber. In addition, the smell of the hot melt adhesive itself is particularly high (the hot melt adhesive cannot have peculiar smell). In addition, the curing speed of the hot melt adhesive should be fast, which can meet the needs of mass production (too slow curing speed will lead to poor adhesion of the filter element).

Weiwang hot melt adhesive has several hot melt adhesive particles specially used for air filter element. They are: w802 hot melt rubber particles, w802b hot melt rubber particles and w730 hot melt rubber particles. Among them, w802 and w802b hot-melt rubber particles adopt imported resin, which will be more excellent in performance. W730 hot-melt rubber particles are domestic resin, which will be more cost-effective. You can choose according to your own requirements. Some customers use ordinary hot melt adhesive particles. Although there is no problem for the time being, Weiwang hot melt adhesive is not recommended. Hot melt adhesive for air filter element must be a special type of hot melt adhesive, which must not be selected at will, otherwise it will bring a lot of unnecessary trouble.
