Development space of PE sheet in the market
Development space of PE sheet in the market:PE sheet has excellent resistance to large-scale life and industrial chemicals. The polymer is non hygroscopic and has good water vapor resistance, and can be used for packaging purposes. PE board has excellent resistance to large-scale life and industrial chemicals. For materials with large molecules, it is suggested that the melting temperature range is 200 ~ 250C. Among the materials that can produce three-dimensional outer film, PE plate is the most suitable material.
Product Name: PE board product name: PE board: English Name: high density polyethylene, Chinese: Polyethylene board. PE board is divided into two kinds: HDPE board and LDPE board. Through the process of anti ultraviolet agents, anti-aging property can be improved and the outdoor service life will be delayed. It has the characteristics of high toughness, good tensile and wear resistance, and can be filled, flame retardant and modified. It can be embossed and sanded. It is widely used in the scale of chemical industry, clothing, packaging, electronics, food and so on. It is widely used in the construction of the enclosure of the ice court, the car board of the tipper and the car board of the earthwork truck in the coal mine area. Very easy differentiation, at 200 degrees with steel. Copper touch more easily differentiation, differentiation, escape erosion. Irritant gas. Small molding temperature scale.
However, PE sheet is very sensitive to the situation stress (chemical and mechanical impregnation), and its heat-resistant aging is poor. It has excellent chemical invariance and can resist the erosion of acid, alkali, organic solution and hot water in the past. 5%, molding temperature: 160-190 ℃. The appearance of the original HDPE is milky white, and it is translucent at certain level in the superficial and thin section. These variables are linked to produce HDPE grades of different uses; achieve a better functional balance. For example, sludge scraper of sewage treatment plant, liner of screw conveyor, impeller of mud pump, pump shaft sleeve, liner of clarified assembly gear and sedimentation tank, etc. The melting temperature is 220 ~ 260C. Some kinds of chemicals will cause chemical erosion. PE plate has good motor energy, especially high dielectric strength of insulation, which makes it suitable for wires and cables.
Because PE sheet has the characteristics of abundant material history, low price, non-toxic, tasteless, good transparency and high-grade mechanical strength, it is used to pack PE sheet into various kinds of packaging containers, which have been widely used in food, medicine, mechanical parts, daily necessities and other packaging. Especially, the application scale of PE resin based plastic film and sheet as packaging materials is growing. It has the characteristics of high toughness, good tensile and wear resistance. The melting point of HDPE board is about 130 ℃, and the relative density is 0.941 ~ 0.960. All products shall be added with different types and numbers of additives as required. Because of its aggressive and fluid characteristics, the best choice of special equipment and molds. HDPE has good motor power, especially high dielectric strength, which makes it suitable for wires and cables. It is one of the most popular and widely used constituent materials in the world
