The environmental protection requirements of special silicone heat transfer hot melt glue mainly include the following points:
Comply with international environmental standards: Hot melt glue should comply with international environmental requirements, such as the EU's ROHS standard, which restricts the use of specific hazardous substances in electronic and electrical equipment, including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers. Hot melt glue that complies with ROHS standards means that its ingredients do not contain these harmful substances or the content is extremely low, and has little impact on human health and the environment.
Non-toxic and odorless: Environmentally friendly hot melt glue should be non-toxic and odorless, which means that no harmful gases or substances will be released during production and use, and it is harmless to human health.
Low volatile organic compound (VOC) content: After melting, hot melt glue should not contain volatile organic compounds such as unreacted monomers, free formaldehyde, and styrene in unsaturated polyester glue. These substances have adverse effects on human health and the environment. Therefore, environmentally friendly hot melt glue should have a low VOC content.
Pass relevant testing and certification: Hot melt glue should pass relevant environmental testing and certification, such as SGS testing. These testing and certification can prove that hot melt glue meets specific environmental standards and has reliable quality and environmental performance.
In practical applications, in order to ensure the environmental performance of special silicone thermal transfer hot melt glue, the following measures can be taken:
Choose products from regular manufacturers: Hot melt glue produced by regular manufacturers usually has more reliable quality and environmental performance, and can provide relevant testing and certification reports.
Check product labels and instructions: When purchasing hot melt glue, you should carefully check the product labels and instructions to understand the product's ingredients, environmental standards, usage methods and other information.
Conduct a small area trial: Before using a new hot melt glue, you can first conduct a small area trial to observe its bonding effect, curing time and other properties, and confirm whether it has adverse effects on the human body and the environment.
