What is PE

PE refers to polyethylene (Polyethylene), wanda shine thermoplastic da aka samu ta hanyar polymerization na ethylene monomers. Polyethylene yana da halaye na kwanciyar hankali mai kyau, juriya na lalata, rufi, sauƙin sarrafawa da gyare-gyare, da kyakkyawan ƙarfin ƙarancin zafin jiki. Abu ne na filastik gama-gari wanda ake amfani dashi a masana'antu da rayuwar yau da kullun.

Dangane da hanyoyin shirye-shirye daban-daban, polyethylene can be divided into high-density polyethylene (HDPE), low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE) and other types. Tsakanin su, HDPE has high hardness, heat resistance and pressure resistance, and is often used in the manufacture of hard plastic containers, water pipes, underground drainage pipes, da dai sauransu.; LDPE has good flexibility and tensile properties, and is often used in the manufacture of flexible packaging films , food bags, fim ɗin filastik, da dai sauransu.

PE is an important plastic material that is widely used in various fields, such as packaging, gini, electronics, mota, medical, agriculture, da dai sauransu. It not only has low cost and good performance, but also has good recyclability and environmental protection, and is an excellent plastic material.

What is PVDF

PVDF refers to polyvinylidene fluoride (Polyvinylidene fluoride), which is a high-performance thermoplastic resin obtained by polymerization of vinylidene fluoride monomer. PVDF has high chemical resistance, high temperature stability, excellent electrical insulation performance, ultraviolet radiation resistance, non-flammability and other excellent properties, so it is widely used in chemical industry, electronics, sararin samaniya, gini, medical and other fields.

PVDF has good processing performance and molding performance, and can be prepared into products of various shapes and specifications by extrusion, injection molding, calendering and other methods. PVDF products have a wide range of applications, kamar:

Chemical field: PVDF can be used to manufacture chemical equipment such as storage tanks, bututu, valves, pumps, da dai sauransu. It has excellent properties such as corrosion resistance and high temperature resistance.

Electronic field: PVDF can be used to manufacture electronic components such as cables, battery diaphragms, and sensors, and has good electrical insulation properties and chemical stability.

Construction field: PVDF can be used to manufacture construction materials such as building exterior wall panels, rufin rufin, and heat insulation materials, and has good weather resistance and UV resistance.

Medical field: PVDF can be used to manufacture medical devices such as medical pipelines and artificial organs, and has the advantage of good biocompatibility.

In a word, PVDF is a polymer material with excellent performance and has broad application prospects.

Application of PE and PVDF in aluminum foil

The application of PE and PVDF in aluminum foil is mainly as a coating material to enhance the moisture resistance, oxidation resistance and corrosion resistance of aluminum foil. Specifically:

PE coated aluminum foil: PE coated aluminum foil is a protective layer formed by coating PE resin on the surface of aluminum foil by extrusion, coating and other methods. PE coated aluminum foil has good moisture resistance, oxidation resistance and corrosion resistance, and can be used to manufacture various fresh-keeping bags, food packaging bags, building insulation materials and other products.

PVDF coated aluminum foil: PVDF coated aluminum foil is a protective layer formed by coating PVDF resin on the surface of aluminum foil by hot melt coating and other methods. PVDF coated aluminum foil has strong weather resistance, chemical corrosion resistance and high temperature resistance, and can be used to manufacture high-end products such as building exterior wall panels, roof materials, aircraft, da motoci.

In practical applications, PE-coated aluminum foil and PVDF-coated aluminum foil can be selected according to specific requirements. Gabaɗaya magana, the price of PE-coated aluminum foil is relatively low, which is suitable for some products with low requirements, while the price of PVDF-coated aluminum foil is higher , suitable for high-demand products.
