Exclusive news: annual output of 1 million tons of polystyrene project settled in Zhoushan
The Management Committee of marine industry cluster zone of Zhoushan archipelago new area of Zhejiang Province and Zhejiang Yisu New Material Technology Co., Ltd. signed a project investment agreement. The new material project with a total investment of 2 billion yuan and an estimated annual output value of 10 billion yuan was officially settled in Zhoushan. The new material project with an annual output of 1 million tons of polystyrene, with a total investment of 2 billion yuan, is expected to use 130000 square meters of land. The project will be constructed in two phases. The first phase is planned to start construction next month, and is expected to start trial production in August next year, with an annual output of 400000 tons of polystyrene; the second phase is planned to start construction in October next year and complete in October 2022.

Expandable Polystyrene Beads The foam pattern is formed from expandable beads (commonly polystyrene) which contain pentane (5-7 wt%) as a blowing/expansion agent. The raw EPS beads (EPS= expandable polystyrene) are delivered at a density of about 38 #/cubic foot in a wide range of initial sizes (10 to 80 mils diameter)
Expandable Polystyrene / EPS: This is PS Foam that uses Pentane gas (C5H12) as the blowing agent. During the material production process called “Polymerisation” the polystyrene resin granules impregnated with the blowing agent. EPS production processes begin in the pre-expansion process where the EPS bead will expand by the heat of steam.
