EPS is made of polystyrene resin as the main body, adding foaming agent and other additives. It is a kind of buffer material that is widely used at present. Polytyrene resin suppliers in China are mainly concentrated in Northeast China, Jiangsu and Zhejiang, Beijing, Tianjin and Hebei, and most of them are small and medium-sized enterprises. Sunresin is a professional manufacturer.
Our company has supervised the moulded polystyrene foam for insulation for five times in five years, and the qualified rate of the products has gradually increased. The quality of products is steadily improving. Apparent density refers to the quality of foamed plastics per unit volume at specified temperature and relative humidity. Apparent density affects other physical performance indicators and directly reflects the cost of the product.
China's insulation market started late, but in the past ten years, it has actively advocated the development of energy-efficient buildings and reduced energy consumption. The expanded polystyrene board thin plastering exterior wall thermal insulation technology has been widely applied, and the demand for expandable polystyrene foam foaming agent has been increasing, which has led to the rapid development of major enterprises. At present, there are about 2000 EPS production enterprises in China. The production momentum of EPS foams is good and the quality of EPS foams is constantly improving. However, the number of large enterprises is relatively small, so Sunresin Company must move towards this goal.
