Introduction of HS code of polyethylene powder coating HS CODE is the abbreviation of “Harmonized Commodity Description and Coding System”. The Harmonization System Code (HS-Code) is formulated by the International Customs Council and the English name is The Harmonization System Code (HS-Code). The basic elements of customs and commodity entry and exit management agencies of various countries to confirm commodity categories, conduct commodity classification management, review tariff standards, and inspect commodity quality indicators are the common identity certificates for importRead More …

Polyethylene Paint, also known as plastic coatings, are coatings applied to plastic materials. In recent years, plastic coatings have been widely used in mobile phone, TV, computer, automobile, motorcycle accessories and other fields, such as automotive exterior parts and interior parts. Components, plastic coatings are also widely used in sports and leisure equipment, cosmetic packaging, and toys. Thermoplastic acrylate resin coatings, thermosetting acrylate-polyurethane resin modified coatings, chlorinated polyolefin modified coatings, modified polyurethane coatings and other varieties, among which acrylic coatingsRead More …

High density polyethylene (HDPE), white powder or granular product. Non-toxic, tasteless, crystallinity of 80% to 90%, softening point of 125 to 135°C, use temperature up to 100°C; hardness, tensile strength and ductility are better than low density polyethylene; wear resistance, electrical Good insulation, toughness and cold resistance; good chemical stability, insoluble in any organic solvent at room temperature, corrosion resistance of acid, alkali and various salts; thin film permeability to water vapor and air, water absorption Low; poor aging resistance,Read More …

The production process of polyethylene can be divided into: High pressure method, high pressure method is used to produce low density polyethylene. Medium pressure Low pressure method. As far as the low pressure method is concerned, there are slurry method, solution method and gas phase method. The high pressure method is used to produce low density polyethylene. This method was developed early. The polyethylene produced by this method accounts for about 2/3 of the total output of polyethylene, but withRead More …

What Is Modified Polyethylene ? The modified varieties of polyethylene mainly include chlorinated polyethylene, chlorosulfonated polyethylene, cross-linked polyethylene and blended modified varieties. Chlorinated Polyethylene: A random chloride obtained by partially replacing hydrogen atoms in polyethylene with chlorine. Chlorination is carried out under the initiation of light or peroxide, and is mainly produced by aqueous suspension method in industry. Due to the difference in molecular weight and distribution, branching degree, chlorination degree after chlorination, chlorine atom distribution and residual crystallinity ofRead More …

Classification of polyethylene Polyethylene is divided into high density polyethylene (HDPE), low density polyethylene (LDPE) and linear low density polyethylene (LLDPE) according to the polymerization method, molecular weight and chain structure. LDPE Properties: tasteless, odorless, non-toxic, dull surface, milky white waxy particles, density about 0.920 g/cm3, melting point 130℃～145℃. Insoluble in water, slightly soluble in hydrocarbons, etc. It can withstand the erosion of most acids and alkalis, has low water absorption, can still maintain flexibility at low temperatures, and hasRead More …
