Plastisols are used for manufacturing of wide range of products as rainboots, hand gloves, upholstery fabrics and tanks, small moulded parts, drum lining, strippable vinyl coating, crown caps lining, electrical insulation filters & covering of electroplating jigs and hangers and for decoration.
Plastisol is a physical mixture of vinyl resins and compatible plasticizers. Unlike most fluid materials they consist of 100 % solids and do not require the evaporation of solvents or water. Fusion at elevated temperatures drives the plasticizer into the resin and changes the plastisol into a homogeneous solid plastic material with the same excellent physical properties commonly associated with other vinyls-flexibility, toughness, abrasion and chemical resistance, unlimited color possibilities and excellent resistance to aging. The Storage of plastisol should not exceed 27 °C (room temp). It should be stored away from the all sources of heat & avoid direct sunlight also.
To obtain the maximum physical properties plastisol must be fused at a temperature of 180-200°C. It is important that the entire mass reach the fusion temperature. The plastisol is heated in various types of heating ovens. The most common of them is an air circulating oven.
This is the most widely used PVC compound; used as:
Granules are most widely used in wires and cables applications of insulation, sheathing, and jacketing. These are easy to process and ready to use compounds which meet the BIS (Bureau of Indian Standards) and International Standards.
