Natural rubbers (NR)

Natural rubber adhesives are commonly employed to bond non-metallic materials such as leather, fabrics, paper, and other rubber products. Natural rubber adhesive formulations are heavily modified with synthetic resins and additives in order to obtain tailored properties. Natural rubber and neoprene are said to have similar properties but neoprene is known to  form stronger bonds and shows good resistance to heat and aging. On the other hand, natural rubber adhesives show good resistance to water, but poor resistance to oils, organic solvents, and chemical oxidizing agents. The long tack retention properties of natural rubber have made it ideal for pressure sensitive adhesive formulations.
