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.
What are the environmentally friendly adhesives? Adhesive is any substance that binds two objects together – essentially glue. The objects adhered together by our adhesive are considered as “substrates”. Have you ever made a grilled cheese sandwich? Once melted and cooled, cheese can be considered as a binder that binds two slices of bread (substrate) […]
