Yes, there are PLA-based hot melt adhesives available on the market. PLA (polylactic acid) is a biodegradable polymer made from renewable resources, such as corn starch or sugarcane, which makes it an attractive material for hot melt adhesive applications. PLA-based hot melt adhesives have several advantages, such as being eco-friendly, having low toxicity, and being compatible with a wide range of substrates.
PLA-based hot melt adhesives can be used in a variety of applications, such as packaging, labeling, and woodworking. They have good adhesion to paper, cardboard, and other cellulosic materials, as well as some plastics. However, they may have lower heat resistance and adhesion to certain substrates compared to traditional petroleum-based hot melt adhesives.
PLA-based hot melt adhesives can be used with conventional hot melt adhesive equipment, such as hot melt glue guns and hot melt tanks. They typically have a lower melting point than petroleum-based hot melt adhesives, which may require adjustments to the processing temperature and application rate.
Overall, PLA-based hot melt adhesives offer a more sustainable and environmentally friendly alternative to traditional hot melt adhesives, and their use is expected to grow as more companies focus on reducing their environmental impact.
To enhance the properties of PLA based hot melts, DPP-VAE products might be considered. DPP-VAE is good water solluble, thermoplastic, and can even be used as compatibilizer.
