Product description
Phthalic anhydride is a colorless crystals, practically insoluble in water, moderately soluble in organic solvents. Shows the properties of aromatic compounds. With alcohols when heated in the presence of sulfuric acid, it forms complex mono - and diesters, with polyhydric alcohols - polyesters ( alkyd resins ). When chlorinated to the benzene ring, it forms tetrachlorophthalic acid anhydride - a monomer for producing self-extinguishing resins. Chlorination of the anhydride group, for example, by the action of phosphorus pentachloride PCl 5 , gives phthaloyl dichloride C 6 H 4 (COCl) 2

VAE emulsion is a kind of macromolecular synthetic material, which is synthesized from polyvinyl alcohol, ethylene, vinyl acid and other raw materials. It is an excellent environmental lotion. It is mainly used in the fields of building materials, textile printing and dyeing, papermaking, coatings, adhesives, labels, and sealing materials. VAE emulsion has good adhesion, which can bond the fibers together to make them more closely combined, thus enhancing the mechanical properties of the product and improving the quality of the product. The price of VAE emulsion is relatively low, which can replace traditional paraffin and emulsion, thus reducing the product cost. At the same time, VAE emulsion has good weather resistance and water resistance, which can extend the life of the product and reduce the maintenance cost of the product. VAE emulsion can significantly improve the performance of the product, making the product have good wear resistance, tear resistance, high temperature resistance, weather resistance and chemical corrosion resistance. It is widely used in the fields of architectural coatings, wood coatings, and fiber products.

olyvinyl alcohol (PVA), with a white powder appearance, is a widely used water-soluble polymer with properties between plastic and rubber. Its applications can be divided into two major categories: fiber and non fiber. 2、 The role of polyvinyl alcohol 1. Polyvinyl alcohol has unique strong adhesion, skin flexibility, smoothness, oil resistance, solvent resistance, protective colloid properties, gas barrier properties, wear resistance, and water resistance after special treatment. 2. Therefore, in addition to being used as fiber raw materials, it is also widely used in the production of coatings, adhesives, paper processing agents, emulsifiers, dispersants, films and other products. 3. The application scope of polyvinyl alcohol is widespread in industries such as textile, food, medicine, construction, wood processing, papermaking, printing, agriculture, steel, polymer chemical, etc.

soda ash is a chemical compound known as an inorganic combination of sodium and carbonate. The chemical formula of soda ash is (Na2CO3). This substance is available in solid, crystalline, powdery and odorless form and has the property of absorbing moisture. In its solid state, its soda appears as a white powder. And when sodium carbonate dissolves in water, carbonic acid and sodium hydroxide are formed.
Some common applications of sodium carbonate include:
As a cleansing agent for domestic purposes like washing clothes. Sodium carbonate is a component of many dry soap powders. It has detergent properties through the process of saponification, which converts fats and grease to water-soluble salts (specifically, soaps)
It is used for lowering the hardness of water
It is used in the manufacture of glass, soap, and paper
It is used in the manufacture of sodium compounds like borax

Fallen Polymer - offers wholesale supplies of its own production - a product for the repair of plastic parts made of polypropylene (PP) and its derivatives. Black triangular rod for repairing parts with a thickness of more than 2.5 mm. Suitable for cases when it is necessary to hide traces of repair of black parts. Recommended for professional use. Product for the repair of plastic parts made of polypropylene (PP) and its derivatives. A 10-meter long triangular rod of black color allows you to hide traces of repairs on black parts. This material is perfect for repairing parts with a thickness of more than 2.5 mm. The advantage of packaging in the form of a coil is a solid long rod, when working with which there are no unused sections, it also ensures mobility, compactness, ease of operation and storage. The welding strength of this material is so high that it does not require laying transverse overlaps in any places other than the exit of the seam, which saves filler rod and working time. If you need a material with identical characteristics, but at a more attractive price with a bright blue rod that allows you to work in rooms with limited lighting, we recommend considering the product fp60017. During the repair process, the material has elastic deformation and is welded in the range of 280-330 C, depending on the additives filling the plastic. Reaching the required temperature for welding can be determined visually when a tear-like shine appears on the part being repaired and on the filler rod. If it is necessary to deform the part, it is enough to heat it to a temperature of 160 - 180 C and give it the desired shape. The strength of a repair seam when welded with original Fullen Polymer materials, subject to welding technology, is about 70-80% of the nominal value.
