Fevicol is a popular brand of adhesive gum manufactured by Pidilite Industries. Fevicol is made using a synthetic resin called polyvinyl acetate (PVA), which gives it its adhesive properties. Here's a general overview of how Fevicol gum is made:
1. Polymerization: The process starts with the polymerization of vinyl acetate monomers. Vinyl acetate monomers are chemically bonded together to form polyvinyl acetate polymer chains. This polymerization reaction usually occurs in the presence of initiators and catalysts.
2. Emulsion: The polyvinyl acetate polymer is dispersed in water to create an emulsion. Emulsifiers and stabilizers are added to prevent the polymer particles from coagulating or settling down.
3. Addition of Additives: Various additives are incorporated into the emulsion to enhance the adhesive properties and performance of the gum. These additives may include plasticizers, thickeners, preservatives, and fillers, among others. The specific additives and their amounts may vary depending on the desired properties of the final product.
4. Mixing and Homogenization: The emulsion is mixed and homogenized to ensure uniform distribution of the additives and achieve a consistent composition.
5. Packaging: The final Fevicol gum is packaged into containers, such as tubes or bottles, ready for distribution and sale.
Now, let's discuss the difference between Fevicol gum and regular gum:
1. Composition: Fevicol gum is made from synthetic polymers, specifically polyvinyl acetate, whereas regular chewing gum is typically made from natural or synthetic rubbers, such as chicle or polyisobutylene.
2. Intended Use: Fevicol gum is primarily used as an adhesive for bonding materials like wood, paper, cardboard, fabric, and other porous and non-porous surfaces. Regular gum, on the other hand, is intended for chewing and is often flavored.
3. Adhesive Properties: Fevicol gum is designed to provide strong and durable adhesive bonding. It forms a solid bond when it dries, creating a permanent attachment between the surfaces. Regular gum, on the other hand, is designed to be chewable and sticky, but it does not provide a lasting bond.
4. Chemical Formulation: The chemical formulation of Fevicol gum is optimized for adhesive properties, ensuring it adheres well to various surfaces. Regular gum, however, is formulated to provide a pleasant chewing experience, with considerations for flavor, texture, and chewability.
In summary, Fevicol gum and regular gum differ in terms of their composition, intended use, adhesive properties, and chemical formulation. Fevicol gum is a synthetic adhesive primarily used for bonding materials, while regular gum is designed for chewing and is made from natural or synthetic rubbers.
