Background
The rubber has very high relative molecular mass and has the ability to crystallize under strain, so that it has excellent cohesive strength and permanent adhesion properties. The long-chain structure of the rubber molecule endows the rubber molecule with good elasticity under low-temperature conditions. The rubber has no polar group, has good compatibility with non-polar tackifying resin, and is prepared into the rubber pressure-sensitive adhesive.
