The performance of PE nozzle

2016-1-22 16:01:01Edit:管理员
PE plastic is polyethylene, English Name: polyethylene, PE, ethylene by a thermoplastic resin polymerization. In the industry, including ethylene copolymer and a small amount of alpha olefin. Polyethylene is odorless, non-toxic, feels like wax, it has excellent resistance to low temperature performance (minimum temperature of up to -70 ~ -100 degree centigrade), good chemical stability, acid and alkali corrosion resistance to most (not resistant to oxidizing acid), room temperature, soluble in common solvents, low water absorption, excellent electrical insulation properties. The nozzle is a device specifically used in composite packaging bag. Therefore, the PE nozzle is a hard mouth made of polyethylene plastic formation.
PE plastic odorless, non-toxic, feels like wax, it has excellent resistance to low temperature performance (minimum temperature of up to -70 ~ -100 degree centigrade), good chemical stability, acid and alkali corrosion resistance to most (not resistant to oxidizing acid), room temperature, soluble in common solvents, water absorption of small, but because of its linear molecules can slowly dissolve in some organic solvents, and no swelling, excellent electrical insulation properties of polyethylene; but to environmental stress (chemical and mechanical action) is very sensitive, heat aging resistance difference.
Properties of PE plastics varies by species, mainly depends on the molecular structure and density.
Because of the characteristics of PE plastic suction nozzle, determines the security of PE material, and by a wide range of mass merchants like. In fact, the applicability is high. Generally used for dairy products, beverage bag bag, bags and bags of Jelly beverage is common; in daily chemical products: detergent washing liquid bag, bag; medical supplies and chemical industries are widely used.
But also because of the material and chemical properties, are not usually suitable for carbonated beverage packaging.
