Hot Melt Glue – EVA, PO & PA Types

Hot melt glue, also called hot melt adhesive is widely used in air filters and oil filters for bonding, shaping and assembling in the production process. Because hot melt glue is environmental protection and fast curing, which can increase production efficiency. Different filter applications have different requirements for the characteristics and materials of filter hot melt glue. Commonly used filter hot melt glue include EVA, PO (Polyolefin), PA (Polyamide), etc. And PA hot melt glue is especially used for oil-resistant and high-temperature filtration.
