The effect of PBR on IZOD impact index and visual quality of HIPS product in Iran marketing

In this study, in addition to a brief description of the production process of styrene and HIPS and study of their properties and structure, effective parameters in HIPS quality and the effect of various factors on the product, especially the impact of various rubbers in the Iranian market, both domestic and foreign, in appearance and index Impact susceptibility (IZOD) has been investigated. In the production process of HIPS, which must have clear and desirable standards, there are often situations that by changing the quality of raw materials and also changing the conditions of the production line and defective equipment of the production unit, product quality is not optimal and may be in the consumer market, Not sold and returned to the company. In addition, it is necessary that production conditions are always up to date and competitive. In this regard, by performing practical experiments on different samples of HIPS product, effective methods in optimizing product quality have been investigated and tried to make changes in process conditions such as temperature, pressure, mixer speed, type and amount of rubber, solvent content, The amount of additives, the use of more advanced catalysts, the best values and results to be obtained to use these results to produce cost-effective and high quality products.
