YD-7719 Polyolefin Air Filter Hot Melt Adhesive can be used for air filter paper bonding and pleating,edge and other processes.
Our range of Synthetic Polymer (EVA) and Polyolefin based products are developed for a wide diversity of applications which includes pleating with separators, edge sealing and the bonding of complex materials from Polyolefin fibres to Polytetrafluoroethylene (PTFE). Our R&D laboratory team is constantly formulating and testing adhesive's performance to meet the increasing demand in the air filtration industry.
The hotmelt separators maintain its uniform spacing between pleats to allow optimal flow of air into and through the filter. Polyolefin based & Synthetic Polymer (EVA) have a wide product portfolio with range of viscosities and curing time to suit desired continuous or inter-mitten glue line pattern and machine line speed. Our hotmelt adhesives are designed with high initial tack and have longer working window to make a perfect pleat to suit our customer different requirements, production processes and geographical standards.

How To Choose Air Filter Adhesive?
There are two main factors affecting the product performance of air filters: one is the fluidity and the other is the bonding strength of the two-component polyurethane potting adhesive, which are also two very key factors in the quality assessment of air filter adhesive. The fluidity of filter glue is mainly determined by viscosity, the smaller the viscosity, the better the fluidity, the larger the viscosity, the worse the fluidity. The bonding strength of the air filter adhesive refers to how much force is needed to separate the filter paper from the aluminium, so naturally the greater the bonding strength of the filter, the better the quality of the product.
For air filter laminates, the hot melt film is generally thinner, e.g. 8g, 10g, 12g, 15g, 20g, etc. If high temperature resistance is required then polyamide based hot melt adhesives is chosen, if high temperature resistance is not required then eva adhesive glue can also be chosen.

FAQ
What are the main characteristics of Polyolefin Air Filter Hot Melt Adhesive?
Odorless: It is a kind of white hot - melt rubber particle, which is odorless and can be used for purifier filters with high indoor requirements, meeting the requirements of environmental protection and human - body safety.
Good viscosity: It has good adhesive force, and can firmly bond filter materials such as non - woven fabrics, paper and foam, ensuring the structural stability of air filters.
Fast curing: It can be quickly cured, which is suitable for the production of medium - speed and high - speed production lines, and can improve production efficiency.
What is its main component?
Usually, it is composed of metallocene - catalyzed polyethylene, hydrogenated petroleum resin, Fischer - Tropsch wax, polyethylene wax, antioxidant and other components. The high crystallinity of Fischer - Tropsch wax can improve the high - temperature resistance of the product, and the addition of polyethylene wax can adjust the performance of the adhesive.
What is the suitable application temperature?
Its application temperature is generally 160 - 180℃. Within this temperature range, the hot - melt adhesive can be well melted and has good fluidity, which is convenient for coating and bonding, and can ensure the bonding effect.
How to store polyolefin air - filter hot - melt adhesive?
It should be stored in a cool and dry place, not exposed to sunlight, and the storage temperature should not exceed 45℃. At the same time, it should be kept away from solvents or chemicals to prevent performance changes caused by contamination. The shelf - life is usually 24 months.
Why does the bonding effect of hot - melt adhesive become poor?
Incorrect temperature: If the temperature is too low, the hot - melt adhesive cannot be fully melted, resulting in poor fluidity and insufficient bonding force; if the temperature is too high, it will lead to the degradation of the hot - melt adhesive, affecting its performance.
Dirty substrate surface: If there are dust, oil stains, moisture, etc. on the surface of the filter material, it will affect the contact between the hot - melt adhesive and the substrate, resulting in poor bonding.
Insufficient glue application amount: If the amount of hot - melt adhesive applied is too small, it cannot form a sufficient bonding layer, which will also lead to poor bonding effect.
What should be paid attention to during operation?
Wear safety glasses, gloves and long - sleeved shirts to prevent hot - melt adhesive from splashing and scalding. Do not heat the colloid above 180℃ without the permission of the supplier, and do not mix hot - melt adhesives of different types to avoid affecting the performance.
