Problems solved by technology

[0002] At present, commonly used composite elastic materials are usually made by adding plasticizers to polyvinyl chloride resins, but the products made by this method have poor elasticity, large deformation, and high brightness, and their application range is greatly limited. It is not suitable for use in instruments that require light protection, such as telescopes, microscopes, camera hoods, and sniper rifle sights. Therefore, a composite elastic material with good performance and a wide range of applications is urgently needed
