What are environmentally friendly low-priced PE sheet ?
PE sheet, also known as polyethylene board, is a thermoplastic engineering plastic board made of polyethylene resin
Advantages of environmentally friendly low-priced PE sheet
Strong corrosion resistance. It has good resistance to various chemical substances such as acid, alkali, salt, etc., is not easily corroded, and can be used for equipment manufacturing and protection in chemical and electroplating environments with strong corrosiveness. It can effectively extend the service life of equipment.
Excellent anti-aging performance. It has good anti-aging performance and can resist the influence of natural factors such as ultraviolet ray and oxidation. It is not easy to have aging, cracking and other problems after long-term outdoor use, and has a long service life.
Limitations of environmentally friendly low-priced PE sheet
Poor flame retardant performance. PE board itself is a flammable material with a low ultimate oxygen index. It is easy to burn when exposed to open flames and produces a large amount of smoke and droplets during combustion, posing a significant fire safety hazard.
Relatively insufficient mechanical strength. Although PE board has certain strength and toughness, its mechanical strength is still relatively low compared to some metal materials or high-performance engineering plastics.
The main function of environmentally friendly low-priced PE sheet
PE sheet has protective functions of wear resistance, corrosion resistance, and impact resistance; Good electrical and electrostatic protection insulation function; Can be used for product and moisture-proof packaging; It also has functions such as shock absorption, buffering, sliding, and filtering, playing an important role in multiple fields.
The working principle of environmentally friendly low-priced PE sheet
Limited heat resistance, generally used continuously at temperatures between 60 ℃ -80 ℃, prone to deformation at high temperatures; The mechanical strength is relatively insufficient, and its performance is not as good as some engineering plastics when subjected to high pressure and high load.
There are various types of environmentally friendly low-priced PE sheets , how to choose the one that suits you
一、Select by performance
1.Mechanical performance. High hardness and rigidity are required for manufacturing structural components that can withstand high pressure, such as industrial equipment casings, large pallets, etc. High density polyethylene (HDPE) sheets can be selected.
2.Heat resistance. When used in high temperature environments, such as near industrial drying equipment and steam pipelines above 100 ℃, HDPE or cross-linked polyethylene (XLPE) boards can better meet the requirements.
二、Select by purpose
1.Packaging field. Used for ordinary product packaging, when high flexibility and transparency are required, LDPE board can be chosen, such as for making plastic bags, cling film, etc. If used for heavy cargo packaging, pallets, etc., high strength and wear resistance are required, and HDPE board is more suitable.
2.In the field of architecture. HDPE waterproof boards with good weather resistance and waterproof performance can be selected for roof waterproofing, floor moisture resistance, etc. In terms of architectural decoration, such as making decorative lines, partitions, etc., PE boards with different densities and surface treatments can be selected according to specific needs.
三、Select according to processing technology
1.Extrusion molding. Suitable for producing continuous length sheets, such as pipes, sheets, etc. If you need to produce large flat and long strip PE products, such as building flat sheets, industrial long strips, etc., extruded PE sheets are a better choice.
2.Injection molding. Capable of manufacturing products with complex shapes and high dimensional accuracy, such as plastic buckets, plastic boxes, toys, etc. If it is necessary to produce PE products with complex shapes and fine structures, injection molded PE boards can better meet the requirements.
四、Taking into account other factors, select
1.Cost budget. When the budget is limited and the performance requirements are not high, such as for disposable packaging, temporary protection, etc., LDPE board has a lower cost and can be given priority consideration.
2.Brand and Quality. PE boards from well-known brands have mature production processes and guaranteed quality. You can also view the quality certification of the product, such as ISO 9001 quality management system certification, relevant industry standard certification, etc.
