Compared with year-end 2012 data, the situation is popular searches have been some changes, attention, foam materials and foam products showed an upward trend. Indeed in recent years, China foam industry average annual growth rate of over 10%, foam products output ranked second in the world. Foam products in agriculture, bubble wrap, foam pipe and profiles, cars, appliances, electronics, transportation and other fields is developing rapidly, giving rise to an investment boom. Let the New Year will also surge in demand for foam products, this performance will become more apparent in the post. The latest statistics show: 2012 January-November, foam insulation box, Shandong, China foam products output of 49.2105 million tons, an increase of 21.11%. 2012 1--10 months, China Foam Products industry scale above industry total main business revenue 1.244574 trillion yuan, an increase of 27.7% in the previous year; total profits and taxes total 91.934 billion yuan, an increase of 25.19%. Double the growth and yield of product demand will drive consumer foam material. Foam insulation boxes of professional production and processing. 1. Press the cell structure classification can be divided into the openings in the foam and closed cell foam categories: opening foam cell communication between each other, mutual ventilation, foam insulation box sea cucumber boxes, foam in the gas phase polymer phase in a continuous phase, fluid from the body by foaming. As for the degree of difficulty with the polymer fluid through their own characteristics and the degree of opening. Closed cell foam is a cell in isolation, evenly distributed in the foam body, mutually connected, completeness bubbles break, the cell wall to form a connection with the foam. Two actual foam cell structure exist, foam insulation box, namely open-cell structure of the foam body with a closed cell structure, closed-cell foam body structure with an open cell structure. If the open cell structure accounted for 90% -95%, they say this foam is open cell structure foam body, otherwise known as closed-cell foam structure. Closed-cell structure on the mechanical properties of the foam is large, it is an important structural parameters of foam products.
