Forecast to expand at a CAGR of 3.1% through 2026, oil filters are seeing rising demand in the automotive market. As manufacturers look to increase output without increasing costs, it’s important they consider the value replacing plastisols with hot melt polyamide adhesives for filter end cap bonding can have on their processes.
Polyamides are 100% solid, thermoplastic hot melt adhesives. This means they yield no VOCs, unlike plastisols.
Also, as hot melt adhesives, polyamides cure by loss of heat. Plastisols, on the other hand, require ovens to cure. This increases energy usage at the plant level to operate the ovens. Because polyamides don’t need ovens, they are able to keep energy usage to a minimum during filter end cap bonding processes.
Further, polyamides help reduce a plant’s carbon footprint. The ovens for plastisols take up significant floor space, requiring an increasingly larger production footprint to meet rising output needs.
Polyamides for filter end cap bonding also aid in worker safety for the following reasons:
- No harmful VOC fumes produced
- No work around a hot oven needed
Additionally, polyamides are able to form a bond using less material per end cap than plastisols. By reducing the amount of material needed, manufacturers are also able to reduce waste and use less adhesive per end cap.
Further, polyamides for filter end cap bonding possess a much shorter set time than plastisols. As a result, production lines are able to keep moving more effectively.
While polyamides can be used to bond metal end caps to filters, they also can be molded to be their own end caps. This capability can yield further process optimizations.
Possessing ideal heat and chemical resistance for oil filters, polyamides help filter manufacturers increase their output capabilities while reducing costs overall. For more information as to how these adhesives can help your filter manufacturing lines, contact us today.
