How to Improve CR Properties?
CR material can be modified to enhance its properties through various methods such as compounding with additives, blending with other polymers, or adjusting curing process during vulcanization.
Additives can work together to enhance the overall properties of Neoprene rubber and tailor it to different applications. Such as antioxidants are added to improve the material’s resistance to degradation caused by exposure to heat, light, and oxygen, thereby extending its service life. Plasticizers are used to increase the flexibility and softness of CR rubber. Reinforcing agents, such as carbon black or silica, are incorporated to enhance the material’s strength, stiffness, and abrasion resistance.
Modifying rubber through adjustments to the curing process involves changing the conditions under which the rubber compound is cured or vulcanized. This process alters the cross-linking density and structure of the rubber, thereby influencing its mechanical properties, such as hardness, elasticity, and resilience. For example, increasing the curing time or temperature can result in a harder and more heat-resistant rubber, while reducing these parameters can yield a softer and more flexible material.
