Sustainable hot-melt adhesives based on soybean protein isolate and polycaprolactone

The combination of synthetic biodegradable thermoplastic with natural vegetable proteins is an alternative poorly explored that might have advantages mostly in reducing the final environmental impact and cost of the adhesive. This article deals with the development and characterization of potentially biodegradable hot-melt adhesives (HMA) based on soy protein isolate and polycaprolactone (PCL), with castor oil (CO) as a plasticizer/...
