en.Wedoany.com Reported - PetroChina Company Limited Guangxi Petrochemical Branch achieved mass production of its optical-grade polystyrene product GPPS-550N on May 10, a product fully developed in-house by the company. This adds a new Chinese supply source to the global optical materials supply chain, characterized by stable mass production capability, proprietary technology, and flexible production features.

The GPPS-550N product features outstanding properties such as high light transmittance and high thermal stability, primarily targeting sectors like LED displays, light guide plates, high-end packaging, and home appliances. Its technical specifications have reached the advanced level of comparable international products.

The product is manufactured at the company's 300,000 tons/year polystyrene unit, which enables flexible switching between multiple grades of general-purpose and high-impact polystyrene.

This mass production milestone equips Guangxi Petrochemical with complete capabilities in the high-quality chemical new materials sector, spanning from independent research and development to large-scale, customized production. As production capacity gradually ramps up, the company will enter a phase of regular supply for optical-grade polystyrene.

Xu Jia, head of the company's 300,000 tons/year polystyrene unit, stated that against the backdrop of continuously rising demand for high-transmittance, high-stability materials in the global optoelectronic display industry, this new large-scale production capacity provides international buyers with more diversified supply options and helps enhance the resilience of the global supply chain for high-end polystyrene materials.

Industry insiders analyze that as the optoelectronic display industry's requirements for material performance continue to rise, the strategic value of high-end polystyrene suppliers with stable mass production capabilities will become increasingly prominent in the global market.
