Polyisoprene latex has excellent performance and has great potential to replace natural latex
Polyisoprene latex is prepared from polyisoprene rubber, emulsifier, stabilizer and a small amount of antioxidant. It is a water-based emulsion of polyisoprene rubber and has high tensile strength and elongation at break. It has the characteristics of high efficiency, strong mechanical and chemical stability, and is not easy to cause skin allergies. It can be used in the production of surgical gloves, condoms, dental rubber dams, physiotherapy belts, urinary catheters and other products. It can also be used as high-end adhesives. Adhesives, food packaging cold sealants. At present, due to the high price of polyisoprene latex, it is mainly used in high-end medical and health products such as surgical gloves.
In industry, companies mainly use rare earth catalysts or lithium catalysts to prepare polyisoprene glue, and then emulsify and desolvate to prepare latex. That is, polyisoprene rubber is used as the basic raw material, and after dissolution, emulsification, desolvation and Concentrate four steps to prepare polyisoprene latex. This method is used to prepare polyisoprene latex, and the mechanical properties of the latex mainly depend on the properties of polyisoprene rubber.
From the perspective of polyisoprene latex production, according to the“China Polyisoprene Latex Industry Market Monitoring and Analysis 2023-2027” released by the Industrial Research Center “Future Development Prospects Research Report” shows that in the early years, the domestic polyisoprene latex industry was always lagging behind due to the development restrictions of the polyisoprene rubber industry. In recent years, driven by Beijing Linshi Refined New Materials Co., Ltd., China Petrochemical Corporation and other companies, domestic polyisoprene latex has achieved mass production, with an annual output of about 3,000-5,000 tons.
From the perspective of new production capacity, abroad, Cariflex, one of the world’s largest polyisoprene latex suppliers, announced in 2022 that it will invest US$350 million to build the world’s largest polyisoprene latex factory in Jurong Island, Singapore. The plant will be put into operation in 2024. After completion, Califlex’s polyisoprene latex production capacity will increase by 50% to 300,000 tons.
From the perspective of the demand side of polyisoprene latex, the performance of polyisoprene latex is similar to that of natural latex and does not contain any protein. It is suitable for the production of products that come into contact with human skin, such as surgical gloves, condoms, etc., and polyisoprene latex Isoprene latex can effectively solve the problem of human allergies caused by natural latex products. At this stage, the global annual consumption of natural rubber latex exceeds 2 million tons. As a substitute for natural rubber latex, polyisoprene latex has great potential to replace natural rubber latex.
Industry analysts said that polyisoprene latex is the best choice to replace natural latex. In recent years, domestic concerns about polyisoprene latex have Research on diene latex is gradually increasing. In addition to Beijing Linshi Refining New Materials Co., Ltd., Zibo Luhuahongjin New Materials Group Co., Ltd., Shanghai Shengda Medical Insurance Co., Ltd., Shanghai Mingli Sanitary Products Co., Ltd. and other companies have also Patents related to the preparation method and application of polyisoprene latex are disclosed, providing a good technical environment for the development of the domestic polyisoprene latex industry.
