Hot melt adhesive particles are solid adhesives that are heated above their melting point before being applied to a substrate. According to the desired application, hot melt adhesive has various appearances and textures. They do not require a curing or drying period as they quickly solidify when cooled to the freezing point. Therefore, hot melt adhesive usually appears on automated production lines that rely on rapid bonding formation.
As a manufacturer of hot melt adhesive granules, Guangzhou Sunlife has invested in manufacturing and extrusion equipment to ensure that our adhesives not only have a clean appearance, but are also the cleanest products available for your application equipment.
Choosing the correctHot melt adhesiveis important because the adhesive required to complete a task can vary greatly. The common hot melt adhesives used by hot melt adhesive suppliers and technology adhesive manufacturers are EVA (ethylene vinyl acetate), metallocene, polyethylene, APAO (amorphous poly alpha olefin), and PSA (pressure-sensitive adhesive).
EVA: One of the ancient hot melt adhesive application technologies. Because of this, there are a large number of raw materials available for preparation. EVA hot melt adhesive is made from petroleum as raw material and has a highly competitive price.
Metallocene: The latest hot melt adhesive technology introduced for the packaging market. Although not as good as based on EVA It is as versatile as hot melt adhesive, but it can provide heat and cold resistance in one formula. This technology will provide a carbon free environment for dispensing equipment.
APAO: When EVA hot melt adhesive cannot meet all requirements, APAO hot melt adhesive is usually used. APAO Technology will provide extended opening hours and extreme temperature conditions. Usually used for automotive applications and professional assembly applications.
PSA: Based on rubber technology, it can provide unlimited residual viscosity. Label inventory manufacturing, automotive assembly, high-speed bottle labeling, and customized applications have become the forefront of this technology.
Mechanical anchoring theory:Adhesive must penetrate into the gaps on the surface of the adhered object and eliminate the air adsorbed on its interface in order to produce adhesive effect.. The mechanical theory is very convincing in explaining the bonding of porous materials such as wood and materials with rough surfaces, and has been verified in […]
Products that have been designed, perfected, manufactured, and inspected to ensure compliance with the highest standards. It’s time for packaging now. The last thing we want is a fragile container that will burst under harsh conditions such as storage, transportation, or shelving. After all, packaging is usually the first impression of a product on potential […]
How to solve the problem of EVA hot melt adhesive becoming brittle in winter and cracking in summer? Summer is coming soon, and many new factory owners may not have encountered this problem before. There are also some who have encountered similar problems, but they were solved by our factory arranging technical personnel to help […]
High temperature resistant hot melt adhesive for books and magazines is mainly based on polyamide resin, so high temperature resistant hot melt adhesive is also known as polyamide hot melt adhesive. Polyamide resin is a linear thermoplastic resin with a large number of repeated amide groups on the molecular main chain. Compared with other thermoplastic […]
