XPE cross-linked foaming production line - equipment overview

XPE is a chemically cross-linked polyethylene foam material that has superior performance, high tensile strength and fine cell size compared to other similar materials. XPE is an ideal material for automotive and air conditioning insulation. In recent years, it has developed rapidly in the sportswear market, such as surfboards, moisture-proof mats, yoga mats, and the like. It also has a certain use in construction, and has recently been widely used in the automobile and packaging industries.

Product thickness: 3mm-15mm

Product width: 1000mm-1200mm

XPE Product Overview

Polyethylene crosslinked foaming material (XPE) is a new type of thermal insulation material with wide application, high cost performance, safety and environmental protection, and international recognition. It has been widely used in China, Europe, America and Middle East. This material has the following characteristics:

    1. Environmental protection: Because the main gas contained in this material is nitrogen, it is non-toxic to the human body and has no pollution to the atmosphere. It is recognized as an environmentally friendly material in the world.

    2. Thermal insulation: The internal structure of the material is a closed-cell structure with a thermal conductivity of 0.03-0.04KCAL/M.H.°C.

    3. Moisture resistance: XPE foam is both a heat insulation layer and a moisture barrier layer, and does not absorb water. Even if the surface is partially damaged, it does not affect the overall insulation and moisture resistance.

    4. Stability: The physicochemical properties of polyethylene crosslinked foamed materials are particularly stable, with good resistance to corrosion, low temperature and aging, and little change in physicochemical properties for long-term use.

    5. Variety: It can be made into foaming materials with different uses such as flame retardant, conductive and high elastic according to different requirements of users.

    6. Aesthetics: It has good elasticity, soft texture and comfortable hand. The surface is generally free of decoration and has a variety of colors to choose from.

    7. Construction: no need for excessive auxiliary layer, only need to cut the bonding to quickly build, no toxic gas and dust.

    8. Processability: The sheet can be processed into end products of different thickness, shape and use according to the user's requirements through corresponding subsequent processing equipment.

    9. Wide range of applications: Mainly used in thermal insulation of cold storage, central air conditioning, pipeline facilities, civil engineering, vehicle and aerospace engineering, packaging of medical equipment, sports equipment, precision equipment, kindergarten floor wall and stadium construction etc.

XPE market analysis

Due to the rapid development of China's economy, the infrastructure of central air-conditioning, large and medium-sized cold storage, pipeline facilities, vehicle and ship manufacturing, civil engineering, agriculture, forestry and animal husbandry has been rapidly developed. Therefore, the market for thermal insulation materials is huge. With the continuous improvement of environmental protection requirements and the continuous improvement of relevant laws and regulations, the central air-conditioning, pipe-sink insulation glass vibrating cotton and civil engineering, cold storage insulation materials XPS, PU board, etc. will be gradually replaced by XPE foam materials. . In China, there are 1,000 large-scale central air-conditioning systems, hundreds of large-scale cold storages, and millions of large and medium-sized automobiles. The water supply, oil supply and gas supply pipelines are millions of meters. A large central air-conditioning system uses hundreds of cubic meters of insulation material, and a large one needs thousands of cubic meters; a 10,000-tonne refrigerator requires more than 2,000 cubic meters of insulation material, and the average vehicle consumption is about 1.2m3; The amount of passenger trains is about 15m3...so the annual demand for domestic insulation materials is more than 6 million m3. According to the amount of XPE foaming materials, which accounts for 1/3 of the total amount of foaming materials, the amount of XPE foaming materials is more than 2 million m3.

       In addition, with the continuous improvement of global environmental awareness, PE foam materials have become the first choice for the insulation materials market in Europe, America, South Korea, Japan and Australia. Now the demand for XPE foam materials in Russia, Kazakhstan, India and the Middle East and Africa is increasing. It is also increasing rapidly. According to customs statistics, the amount of XPE foamed materials exported to foreign countries in China in 2014 was nearly 1.28 million cubic meters. In 2015, it has reached 1.5 million cubic meters. It is expected to exceed 1.8 million m3 in 2016, showing a rapid upward trend.

       According to the above data analysis, the annual market demand for XPE foam materials is more than 2.5 million m3, while the domestic XPE foam materials manufacturers are less than 40, with a total output of less than 800,000 m3, which is less than 1/3 of the market demand. . Therefore, the domestic and international market space and development potential of XPE foam materials are enormous.

XPE production line features and production process

The polyethylene cross-linked foaming coil production line produced by the company is based on the summarization of the advantages and disadvantages of Han, Japanese and Taiwan equipment. It has made many improvements to the key parts of the equipment, and also according to the general requirements of customers. Some configurations have been optimized and independently developed, and the independent correction of the sheet material with independent intellectual property rights, furnace energy saving, waste edge winding, mesh belt over-bias protection, etc., so that the quality performance of XPE foaming equipment is greatly improved. Improvement has truly achieved the goal of reasonable structure, stable performance, energy saving, environmental protection, safety and efficiency.

     The main process of XPE production:

    1. PE and various additives are weighed according to the proportion of granulation formula → flat double extrusion granulation →

    2. PE and the masterbatch are weighed according to the ratio of the mastering formula → the mixer is stirred regularly → extrusion filming →

    3. Heating foaming → cooling setting → trimming and winding → quality inspection → packaging and storage.

    The production line is easy to learn and the employees can usually work after half a month of training.

The advantages of the polyethylene (XPE) cross-linked foamed coil production line manufactured by the company are summarized as follows:

1. Price concessions, about 15% lower than the same industry. The average price of the foaming machine auxiliary machine market is about 1.2 million, and the company's price is 105-108 million yuan;

    2. Quality assurance, solid materials. Insulation layer thickness: top 150mm (aluminum silicate insulation cotton), side plate 120mm;

    3. High output, higher than 20% in the same industry. Now the foaming output of the same industry is 180kg/h, and the company can increase it to 220kg/h (more than 50m3);

    4. Reduced energy consumption. No longer need an internal mixer or an open mill, which greatly saves electricity consumption and reduces the number of users;

    5. After-sales guarantee. 36 hours to the on-site service, giving solutions within 8 hours;

    6. The manufacturing cycle is shortened. The current manufacturing cycle is around 90 days, and the company can be reduced to 75 days.
