International research and development of PVC heat stabilizer and industrialization has gone through three stages of development: the initial stage of invention. Optimization stage and maturity stage.
The initial invention phase began in the mid-1920s and early 1950s. During this phase, numerous experiments were carried out to evaluate the possibility of innumerable materials as PVC thermal stabilizers. As a result, four types of compounds were confirmed to have effective thermal stabilizing effect on PVC in the early 1950s. They were Lead lead thermal stabilizers Organic tin thermal stabilizers Mixed metal salt thermal stabilizers and organic auxiliary thermal stabilizers.
The optimization phase started in the 1950s and 1970s. PVC industry at this stage has entered a period of rapid product development and rapid growth, thus promoting the development of PVC heat stabilizer, and promote the optimization of heat stabilizer products. Commercial focus shifted from discovering new materials to optimizing existing products, including optimizing formulation and dosage as well as designing synergistic heat stabilizers and lubricant systems to meet the diverse needs and preferences of a large number of users. Thousands of specialty PVC thermal stabilizers have been developed in the process by manufacturers of thermal stabilizers and lubricants throughout the world. This is a fast-growing period of competition, contributing to the continuous improvement of the price / performance of heat stabilizer products.
After the mid-1970s, the focus of development shifted as PVC thermal stabilizers entered a mature stage. This development is driven by the rising momentum of green sport and industry towards cheaper and better performing chemistries. The continued need to use safer and more convenient chemical additives is impeded. The hallmark of this phase is the emergence of a well-designed heat stabilizer - lubricant "one pack" product.
