PS white oil (polystyrene special white oil) has broad demand and the industry is developing toward high quality.

White oil refers to mineral oil products obtained by refining petroleum and can be widely used in chemistry, textiles, petrochemicals, plastics, medicine and other fields. Among them, textile auxiliaries, PS (polystyrene), and silicone glue are the main demand ends of the white oil downstream. PS white oil is a special white oil for polystyrene, which refers to the white oil used in polystyrene production scenarios.

Polystyrene is a polymer obtained by polymerization of styrene. Due to its high molecular weight, a certain amount of mineral oil needs to be added during the production process to reduce mechanical losses, improve melt fluidity, and reduce melt adhesion. sex. The mineral oil used is generally PS white oil (special white oil for polystyrene), which has the advantages of good photothermal stability, low aromatic content, good processability, and good compatibility with PS. In the polystyrene production process It can not only improve melt fluidity and reduce melt adhesion, but also improve product color and impact resistance, increase product plasticity and toughness, and reduce intermolecular friction.

According to the“PS White Oil (Polystyrene Special White Oil) Industry Market In-depth Research and Investment Prospects Forecast Analysis Report 2023-2028” released by the Industrial Research Center It shows that under the background of the rapid development of the domestic polystyrene industry, its output continues to increase, which in turn drives the increasing demand for PS white oil market. At present, polystyrene has been widely used in electronics, building materials, packaging, medical and other fields, and many companies such as Xinghui Environmental Protection, Chimei Chemical, CITIC Guoan, and Secco Petroleum have entered the market. In 2022, its domestic output will exceed 400 Thousands of tons. Against this background, my country’s PS white oil market demand in 2022 will be approximately 46,000 tons, and the demand space is vast.

PS white oil is an important material required for polystyrene production. The market requirements are high. Key indicators such as aromatic hydrocarbon content, sulfur and nitrogen content, easy carbonization, and ultraviolet absorbance of the product are required to reach the food and pharmaceutical level, and the industry entry threshold is high. At present, domestic enterprises specializing in the production of PS white oil mainly include Zhejiang Zhengxin Petroleum Technology, CNOOC Refining, PetroChina Karamay Petrochemical, Sinopec Jingmen Branch, etc. The number of enterprises is relatively small. Therefore, some high-viscosity PS white oil in China still relies on imports. In the future, local companies will need to continuously improve their technical level and accelerate the development of high-quality PS white oil products. There is huge room for industry growth.

Industry analysts said that PS white oil is one of the key materials required in the production process of polystyrene. , currently driven by the rapid development of the domestic polystyrene industry, its demand is increasing, and the industry shows good development prospects. However, due to technical limitations, there are currently only a small number of enterprises specializing in the production of PS white oil in my country, and the quality level and added value of domestic products are low. In the future, the development and production of high-quality PS white oil products will be the general trend of industry development, and local enterprises still need to Continue to strengthen product innovation and process innovation.
