How to choose environmentally friendly hot melt adhesive? At present, the functions and applications of hot melt adhesive have received widespread attention, but the environmental issues of hot melt adhesive are often overlooked. Has environmental protection become a bottleneck for the further development of adhesives? Solving the problem of environmental pollution has become an urgent task nowadays.
Hot melt adhesive is mainly made of EVA, rubber, polyolefin, polyamide and other materials, supplemented by high molecular weight materials such as tackifiers and softeners. Solvent free and non-volatile. Compared to solvent based, oil-based, and water-based adhesives, hot melt adhesive is more environmentally friendly.
However, the layers in environmentally friendly hot melt adhesive are different. From the environmental requirements of the European Union and the United States, many hot melt adhesives currently on the market do not meet the standards. Many hot melt adhesive companies, in order to reduce costs, extensively use environmentally unfriendly and inexpensive materials, and classify their produced hot melt adhesives as non environmentally friendly products.
How can we determine if the hot melt adhesive we purchase is environmentally friendly? At present, international environmental protection hot melt adhesive testing projects include ROSH standards, formaldehyde testing, determination of 18 types of polycyclic aromatic hydrocarbons, halogen fluorine, chlorine, bromine, iodine content, determination of total octane yellow compounds (PFOS) content, determination of nonylphenol formaldehyde polyvinyl chloride ether (NDEOS) content, and REACH84 testing. Medical hot melt adhesive also undergoes skin insensitivity testing.
More and more books are using EVA hot melt adhesive for binding process. Almost all of them are used in large, medium, and small processing plants across the country. There will still be an upward trend in the future. This is because using this adhesive results in fast book publishing speed, short cycle time, aesthetically […]
As a common packaging material, cardboard boxes play an important role in logistics and transportation. The reason why cardboard boxes can carry and protect items is largely attributed to the bonding effect of packaging hot melt adhesive. This article will explore the bonding effect of packaging hot melt adhesive from the following aspects: the basic […]
Pearl cotton, also known as EPE, is a foamed polyethylene polymer. Pearl cotton has many advantages such as water and moisture resistance, shock resistance, sound insulation, thermal insulation, good plasticity, strong toughness, recycling, environmental protection, strong impact resistance, and good chemical resistance. Features: low density, good flexibility, high recovery rate; Better shock resistance than polystyrene […]
Hot melt adhesive is ubiquitous, yet constantly invisible. Hot melt adhesive manufacturers’ products are widely used in books, pearl cotton, clothing, shoes, handbags, cardboard packaging, etc. When choosing to use hot melt adhesive, I usually don’t pay attention, but when problems arise, it can be very embarrassing. So whether it’s book binding manufacturers, shoe and […]
