PolyVinyl Alcohol (PVA) is a water-soluble synthetic polymer in the form of a white powder or molten cream that decomposes at 230 ° C. Polyvinyl alcohol has a very attractive property and that is its biodegradability. Vinyl alcohol monomers are weak and polyvinyl alcohol is obtained by replacing the acetate group in vinyl acetate with hydroxyl groups.
Polyvinyl alcohol, part of which is hydrolyzed, has a lower melting point and solubility, and by increasing its molecular weight, the viscosity of polyvinyl alcohol increases
Safety Tips for Consuming Polyvinyl Alcohol
Skin contact: In case of skin contact, the contact area should be washed with soap and water, the door should be covered with a moisturizer, and a doctor should be consulted if the irritation is severe
Eye contact: If the lens is inside the eye, it should be removed and immediately rinse the eyes with cold water for 15 minutes and see a doctor
Inhalation: The poisonous trace should be transferred to the open air and in case of shortness of breath, use an oxygen device and see a doctor
Gastrointestinal: Do not vomit if poisoned person eats polyvinyl alcohol unless done by a medical professional. If the person is wearing tight clothing such as a collar, tie, belt or girdle. See your doctor if you have any symptoms
Uses of polyvinyl alcohol
PVA has a good property for film production and the film made of it has excellent adhesion, solvent resistance, abrasion resistance, high tensile strength and high barrier oxygen salts. Due to the fact that PVA has active hydrophilic and hydrophobic groups, it can act as a surfactant and can be used as a protective colloid in polymerization emulsifier and polymerization polymerization.
The most important use of polyvinyl alcohol is in the industries of adhesives, paints, textiles, paper coatings and polyvinyl ether
The most common use of polyvinyl alcohol is in the construction industry and in concrete joints and cement and as an additive in concrete and cement
Polyvinyl alcohol is a very good material for gluing and increases the resistance to solvents, greases and oils. Films made from polyvinyl alcohol have a very high elasticity
Cosmetics, veneering, coating to prevent abrasion
Polyvinyl alcohol is used as an emulsifier in the cosmetics industry
It is also used in agricultural industries to increase soil adhesion and prevent soil erosion and production of chemical fertilizers, pesticides and herbicides
Sizing paper and textiles and producing photographic paper
Production of gloves resistant to chemical raw materials
Production of artificial tears and eye drops for lubrication
Production of disposable detergent packages
