The global polyurethane (PU) hot-melt adhesive market size was valued at USD 1,311.33 million in 2021. It is projected to reach USD 2,537.38 million by 2030, growing at a CAGR of 7.61% during the forecast period (2022-2030).
Polyurethane hot melt, also known as PU hot melt, is an adhesive that is heated and poured from a cartridge or slug, as opposed to conventional hot melt, which is in the form of a stick or pellet. PU is also unique because it solidifies through air moisture to form an unbreakable, ultra-strong connection. PU is perfect for many applications, including woodworking, finish carpentry, shoe repair, furniture restoration, shattered glassware repair, laminate countertops, construction and renovation, ceramic ceiling tiles, and more because of its strength, durability, and quick setting time. The polyurethane hot adhesives market is anticipated to grow due to increasing industry demand.
In the past, sectors like construction, furniture, and automotive used solvent-based adhesives. However, solvent-based adhesives have several adverse effects on the environment, including soil, water, and air pollution, which can be hazardous to both human health and the ecosystem for both flora and wildlife. For instance, breathing solvent vapors can increase your risk of developing lung and asthma. Construction-related solvents eventually contaminate groundwater after seeing into the soil. The release of dispersion (emulsion) adhesives into the environment might also result in specific issues. These worries have pushed the market under study as stakeholders turn to more ecologically friendly adhesive choices as PU holt melts.
PU hot-melt adhesives cause minimal to no pollution and have negligible environmental effects. They are also non-combustible and do not require any ventilation. Due to the cheap price point, these are also appropriate for big-volume industries like packaging and construction because it keeps costs down. Furthermore, the government and regulatory bodies encourage the use of PU hot-melt adhesives rather than solvent-based.
In the automotive industry, PU hot-melt adhesives are frequently used for significant bonding structures and hang-on items, such as doors, tailgates, hoods, and trunk lids. Additionally, they are employed in place of, or even in addition to, mechanical fasteners for chassis parts. They are the perfect reinforcement for metal stamping pieces during the installation of the body to the chassis because they give constant wet-out across uneven surfaces. In the automobile industry, they are also employed as fastener adhesives for power train applications, applications involving electric car batteries, exterior and glass assembly, bonding, sealing, and isolation, among other things. Ride-sharing firms like Uber and Ola, combined with demand shocks in countries like India, have caused a dramatic decrease in vehicle sales over the past year (production follows the sales demand for automobiles with a slight lag).
In the packaging business, PU hot-melt adhesives are widely used. The majority of their applications include sealing and closing cartons. One of the biggest end-user industries for PU hot-melt adhesives is the packaging sector. Compared to other adhesives, such as water-based adhesives and other hot-melt adhesive formulations, PU hot-melt adhesives extract moisture from the substrates and the environment to form a stronger bond.
In addition, polyurethane hot melt provides greater curing and adhesion than conventional hot melts, making it a wise choice in the expanding industrial packaging sector. Transparent cases are frequently used for packaging cosmetics, fragrances, and beauty goods. These hot-melt adhesives are employed to seal packages that guarantee a clear application and aid in the distribution of an ideal finished good. The packaging and electronics industries are anticipated to dominate the market in the coming years due to all the previously mentioned causes.
The global polyurethane (PU) hot-melt adhesive market is segmented by type and application.
Based on type, the global PU hot-melt adhesive market is bifurcated into non-reactive and reactive.
The reactive segment is the highest contributor to the market and is expected to grow at a CAGR of 7.61% during the forecast period. The reactive polyurethane hot-melt adhesives are heated before use, applied while still molten, and strengthened by a physical hardening process as they cool. The PU adhesive combines with the water molecules or humidity (in the air) and becomes an elastomer. Reactive hot-melt adhesives offer a considerably stronger bond with improved resistance to moisture, heat, and chemicals after crosslinking is finished. The adhesives' reactive groups broaden the range of adhesion by forming stable chemical interactions with compatible reactive partners on the surface of the substrate. The reactive hot melt adhesives are based on various kinds of polyurethane and polyolefin. It is also offered in granulate form for applications requiring excellent quality and aesthetics as a high-performance PUR adhesive. Additionally, they attach significantly more effectively to untreated substrates like polyethylene (PE) and polypropylene (PP). Also, they do not have any free isocyanates. High heat and water resistance, quick setting periods, adherence to various materials, and low processing temperatures are all benefits of reactive polyurethane hot-melt adhesives.
Contrary to reactive resins, which are made of one or two-component resin systems, non-reactive polyurethane hot-melt adhesives are based on high molecular weight polymers. The non-reactive polyurethane hot melt adhesives are distributed between two surfaces that need to be linked and bonded in the form of a thin layer of high molecular weight polyurethane. Thermoplastic granules that may be extruded or heated in holding tanks to melt to produce glue sticks for a hot-melt gun or sticky films for industrial heat presses are available as non-reactive polyurethane hot-melt adhesives. Paper, board, wood, metals, plastics, and fabrics can all be joined together with polyurethane hot-melt adhesives. The most common method of using polyurethane non-reactive hot-melt adhesives is to sandwich them between two substrates, heat them to a temperature over their melting point, and then press the two substrates together while holding them in place.
Based on applications, the global PU hot-melt adhesive market is bifurcated into paper, board and packaging, healthcare, automotive, furniture (woodworking), footwear, textiles, electrical and electronics, bookbinding, and other applications.
The furniture (woodworking) segment is the highest contributor to the market and is expected to grow at a CAGR of 7.49% during the forecast period.
