Answer directly Hot melt adhesive granulesAlthough it does not contain solvents, there are still environmental requirements for export and domestic sales, mainly depending on the limits of harmful substances, odor, and compliance with food contact regulations. Here is a list of commonly used standards and tests. Environmental Protection and Compliance Checklist RoHS：Limit values for heavy […]
temperature change of hot melt adhesive hot melt adhesive is a thermoplastic material – or polymer – that usually becomes flexible at warm temperatures. On the contrary, during the cooling process, the hot melt adhesive solidifies and eventually forms a well-known long-lasting bond. Temperature and its variation patterns have a significant impact on the performance […]
Hot melt adhesive granulesThe manifestation of aging After long-term storage, hot melt adhesive particles may become yellow and brittle, and the bonding strength may decrease, but the degree of attenuation is closely related to the storage conditions. Only by scientifically evaluating the degree of aging can we decide whether to continue using or replace the […]
