Application of filter element adhesive. Filters are also known as filter elements. Common filters are divided into two categories: air filters and oil filters. Air filters are mainly used to purify air. It is generally used in automobiles. According to their uses, they can be classified into air filters and air conditioning filters.
The main function of a car air filter is to purify the air inside the engine and prevent dust in the air from causing damage to the engine. Air filter = The filter through which external air enters the front of the engine = air grille.
The main function of a car air conditioning filter is to purify the air inside the vehicle. Air conditioning filter = Pollen filter = Filter before outdoor air enters the driver’s cabin air conditioning system = air conditioning grille.
According to appearance, they can be classified into high-efficiency filters with separators and high-efficiency filters without separators. Among them, the air filters used for partitions are made of aluminum strips, etc., and are relatively heavy. The partition is made of hot melt adhesive and is lightweight.
The oil filter is mainly used to block dust, metal particles, carbon deposits, fume particles, etc., and is mainly used to protect the engine. Generally, PA polyamide hot melt adhesive is mainly used. PA type hot melt adhesive features high-temperature resistance and oil resistance.
Filter element adhesives generally use EVA hot melt adhesive and PO polyolefin hot melt adhesive. This hot melt adhesive features rapid curing and is suitable for mass production, especially for high-efficiency filters without separators. This glue mainly serves to fold the lines of filter paper, fold the edges of filter paper, fix the mesh film, and fix the filter element frame, etc.
What is hot melt adhesive for corrugated plastic packaging? Corrugated plastic packaging is a rapidly developing field, and so far, it is difficult to find hot melt adhesives that can provide excellent adhesive strength and curing time for corrugated plastic packaging. Corrugated plastic mainly includes three types: laminated board, profiled board, and honeycomb board, also […]
Answer directly Hot melt adhesive granulesAlthough it does not contain solvents, there are still environmental requirements for export and domestic sales, mainly depending on the limits of harmful substances, odor, and compliance with food contact regulations. Here is a list of commonly used standards and tests. Environmental Protection and Compliance Checklist RoHS：Limit values for heavy […]
Direct conclusion Small batch, multiple varieties, frequent order changes (such as graphic printing, sample box sampling), choosehot melt adhesive powderMore flexible; Continuous large-scale production, equipment installation (book and magazine linkage line, sealing spray glue machine), orHot melt adhesive granulesMore stable and cost-effective. Both are of the same kindhot melt adhesiveThe core difference lies in how […]
