The first 90‑ton trial‑produced batch of new polystyrene grade GH660LS from Sinopec Guangzhou Company has been dispatched as scheduled for delivery to custom‑order customers.
Polystyrene GH660LS is another newly‑developed product built on GH660, the company’s existing product with national‑level green product certification. Belonging to the impact‑resistant polystyrene series, it delivers favorable flowability and impact resistance, and is widely used in equipment housings, toys, household tableware, modified plastics and film products.
Since the beginning of this year, Sinopec Guangzhou Company has further implemented the “One Product, One Strategy” philosophy. It has intensified customer visits to keep abreast of market trends, and developed market‑oriented products to continuously meet market demands. Early this year, the new‑product R&D team received customer feedback requesting a new grade to satisfy their application requirements. In response to such demands, the team held multiple special seminars to sort out technical specifications and influencing factors, discuss raw‑material formulations and production parameters, and formulate trial‑production plans. During trial production, R&D technicians strengthened process monitoring and optimized production parameters according to real‑time operating conditions. Inspection staff provided close coordination and timely product analysis to supply data support for product tuning. The new product was successfully manufactured in the end.
