Polypropylene sheet is a semi-crystalline material. It is stronger and has a higher melting point than PE. Because homopolymer PP is very brittle when the temperature is higher than 0 °C, many commercial PP materials are random copolymers with 1 to 4% ethylene or pincer copolymers with higher ethylene content. The copolymer-type PP material has a lower heat distortion temperature (100 °C), low transparency, low gloss, low rigidity, but has a stronger impact strength.
The characteristics of polypropylene sheet are light weight, uniform thickness, smooth and smooth surface, good heat resistance, high mechanical strength, excellent chemical stability and electrical insulation, as well as non-toxic, harmless, non-flammable and other characteristics.
Polypropylene sheets are used in large-scale acid and alkali resistant equipment, environmental protection equipment, waste water and waste gas discharge equipment, scrubbers, clean rooms, semiconductor factories and related industrial equipment, and are also the first choice for making plastic water tanks. For stamping boards, punching mattress boards, etc.
Regarding the use of materials, the needs of all walks of life in the society are different, and the specifications for use are different. As for the commonly used boards, polypropylene boards are the board materials that have the best reputation. This board is made of polymer materials. Chemically synthesized materials have good functions such as compression resistance, corrosion resistance, environmental protection and non-toxicity, and are suitable for many industries. Nowadays, the electronics industry also needs the use of such sheets, so what is the use of polypropylene sheets in the electronics industry? ?
Nowadays, in the maintenance of the electronic industry, it is necessary to be cautious about the packaging of conductive items. For example, the current IC series packaging is applied to the packaging of electronic goods for safe use. Then this packaging material is relatively expensive, so the electronics industry has turned its attention to polypropylene sheet, which has excellent anti-conductive properties. Its conductive point value is very high, it is a low-end product, and it happens to be suitable for electronic packaging goods.
The purpose of packaging with polypropylene sheet is to cause the electrical appearance of the charged electronic items to connect with other items in the future, resulting in the appearance of sparks due to the collision of the parts due to the electrical conductivity, and finally the appearance of fire, so use this method. This kind of low-edge sheet is the safest for electronic items.
Polypropylene sheet not only has excellent functions for other industries, but also brings convenience to the electronics industry. This sheet is a representative of new energy-saving sheets.
