Introduction: Fevicol type adhesive come
under the category of Synthetic resins and latex adhesives are made from
Polyvinyl acetate is thermoplastic, odorless, tasteless, non toxic,
essentially clear and colorless resin.
It has a non Crystalline and relatively branched rather than linear structure.
Most grades of resin have somewhat broad molecular weight distribution. They
do not melt but soften over a temperature range. The resin is unaffected by
sunlight, ultraviolet light and air, further more it will absorb a small
amount of water. Polyvinyl acetate is neutral and non-corrosive.
The Various grades have good heat stability below 100ºC, show slight discoloration
at approximately 150º and decompose at 50ºC show slight discoloration at approximately
150ºC but brittle at 10ºC to 15ºC. The adhesive industry is currently the most
important outlet for polyvinyl acetate.
Adhesives are made in various types and may be synthetic or natural:
The term synthetic adhesive means the adhesive which is prepared by using synthetic
chemical such as synthetic resin. Polyvinyl acetate is now used in adhesives for
various applications such as Book binding, Paper bag, Milk Can, Drinking straws,
Envelopes, Gummed Tapes, and Foils etc.
Vinyl Acetate Adhesive:
The vinyl acetate adhesive is also used for lamination, combination of two or more
plies of material into a now composite. Polyvinyl alcohol is being imported from
countries like Germany, FRP, France, U.K, Netherlands, Japan, Hungary, Italy,
U.S.A and Belgium. Synthetic adhesives Produced in India are mostly based on
vinyl Acetate Monomers (V.A.M).
Vinyl Acetate Monomers:
VAM is used in from of its various derivatives like Polyvinyl Alcohol and Polyvinyl
Acetate, Ethyl Vinyl Acetate etc. Currently, the major applications of adhesives
are in furniture, packaging, automotive and construction. Woodwork and furniture
sector has been the major growth driver for adhesives.
Packaging is another industry:
That influences the demand of adhesives. Adhesives are primarily required in
making containers and flexible packaging. Increasing plastic and polymer use
in vehicles, in order to reduce weight for enhancing efficiency will most likely
drive adhesives and sealants market size.
Packaging applications includes carton boxes, envelopes, carton closures, cups,
flexible packaging, specialty packaging, bags and disposables, PU, water based
and hot melts are widely used in packaging applications.
