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, foam insulation box, this performance will become more apparent in the post. The latest statistics show: 2012 January to November, China total 49,210,500 tons foam products, foam insulation box fry boxes, 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. 1. Press the cell structure classification can be divided into the openings in the foam and closed cell foam categories: opening foams are interconnected between the cell, foam insulation box, Shandong, mutual ventilation, gas phase polymerization foam was white was the 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, namely open cell structure foam body with 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. Electronic product cushioning foam packaging is generally in corrugated boxes, cartons on the basis of the inner foam packaging foam packaging foam increase, bubble film or corrugated pads, so that products meet earthquake purposes. The company has sales management, technology development and other talents. We can design and production for a variety of products to meet customer requirements for Earthquake packaging materials. Foam insulation boxes sent to the country, much foam (certified), foam insulation foam box from Shandong great Limited. Shandong great foam Ltd. (www.rzdayou.com) Shandong Rizhao, plastic materials, leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
