Polyvinyl alcohol or poval (abbreviated as PVA) is a kind of water-soluble resin produced by polymerization and alcoholysis of vinyl acetate. Due to its unique features of high cohesiveness, membrane tenacity, smoothness, solvent resistance, gas inhibitor, wear resistance, protective colloid, and waterproof after specially treated, polyvinyl alcohol is widely applied in textile, building, papermaking, packing, timber processing, agriculture, printing, polymer chemical, ceramic, iron and steel, electronic, electrolytic, electroplating and other industries. PVA fiber (Polyvinyl Alcohol fiber), as reinforcement in concrete. As excellent synthetic fibers, it can also be spun and acetalized to make vinylon fiber.

PVA 124 is mainly used as a warp dressing agent; textile finishing agent and the raw material of vinylon in textile industry; used as 107/801 glue, an additive of cement and mortar, inner and outer wall paints, and mounding board binder in construction upholstery industry; used as a well-fixing agent in petroleum exploitation; used in cosmetic, printing, medicine and electronic, also can be used in chemical industry, paper industry and agriculture, etc.

PVA 224 is raw materials of vinylon fibers,construction,paint additives, mainly used in textile,fabric finishing agents.

PVA 1788 is chiefly used for coatings, adhesive, dispersing agents, emulgents, textile sizing materials, sensitize coatings and so forth.

PVA 1799 is chiefly used to produce textile sizing materials, coatings, adhesive and it is widely used for paper processing, emulsifying agents, dispersants and blocking colloids. Besides, it can be employed as membranes, soil modifiers,and production materials of vinylon fiber.etc.

PVA 105 is an environmental water-soluble high weight polymer, non-toxic, non pollution, has good film forming property, emulsifying property, bond property and the spining property, mainly used for textile materials, textile finishing agent, paper processing aids, adhesives, emulsifiers, polyvinyl alcohol acetal material, film and Vinylon, high strength and high modulus PVA short fiber, protein fiber.

PVA 205 appears as white powder, is a use of a wide range of water-soluble polymers, plastics and rubber between the performance between the use of its fiber and non fiber can be divided into two major purposes.

PVA 117 is chiefly used to produce textile sizing materials, coatings, adhesive and it is widely used for paper processing, emulsifying agents, dispersants and blocking colloids. Besides, it can be employed as membranes, soil modifiers,and production materials of vinylon fiber, etc.

PVA 217 is chiefly used for coatings, adhesive, dispersing agents, emulgents, textile sizing materials, sensitize coatings and so forth.

Hydrofluoric acid
or can be known as hydrogen fluoride (HF) is a solution of hydrogen fluoride anhydrous in water. It is a valued source of fluorine and is the precursor to numerous pharmaceuticals such as fluoxetine (Prozac) and diverse materials such as PTFE (Teflon). Hydrofluoric acid is a highly corrosive acid, capable of dissolving many materials, especially oxides. Its ability to dissolve glass has been known since the 17th century, even before hydrofluoric acid had been prepared in large quantities by Carl Wilhelm Scheele in 1771. Because of its high reactivity toward glass and moderate reactivity toward many metals, hydrofluoric acid is usually stored in plastic containers (although polytetrafluoroethylene is slightly permeable to it). Bouling Chemical (Group) Ltd is professional hydrofluoric acid suppliers provide fluosilicic acid, industrial hydrofluoric acid, hydrofluoric acid 40%, hydrofluoric acid 55%, hydrofluoric acid 70% with factory price and high quality!
