Natural Rubbers (NR) for Adhesives and Sealants: Overview

Natural rubber appears as an elastic, cream-colored material with high stretch and recovery properties. Key features include high initial tack, excellent green strength, and good flexibility across moderate temperature ranges. Natural rubber adhesives excel in applications like temporary bonding, packaging, and consumer products where quick stick and clean removal may be required. 

Industry trends show renewed interest in natural rubber as a sustainable alternative to synthetic polymers. Various grades exist based on processing methods and additives, including smoked sheet rubber, pale crepe, and deproteinized natural rubber, natural rubbers in latex forms, and modified natural rubbers.
