PVC plastisols are in used in numerous applications such as flooring, coated textiles, inks, dip coatings, artificial leather, carpet backing and car underbody sealants.Plastisols are a generic name for PVC particles dispersed in plasticizers that, when heated, fuse together to form a tough plastic film.
PVC Plastisols additives are fluid dispersions of finely divided plastic resin particles in a liquid plasticizer and a small amount of a diluent (solvent). These dispersions are relatively stable.
Fillers, pigments, adhesion promoters, rheology auxiliaries (separation inhibitors), heat stabilizers, blowing agents, reactive (capable of cross-linking) additives, and water-absorbing substances (calcium oxide) are some of the additional additives that are added to the plastisols.
Fillers made of hollow glass microspheres are mostly used to reduce the density of low density seam sealers while also controlling the viscosity, making the unfluxed plastisol solution sag, and adding thixotropy, which extends the sealer’s shelf life.
Plastisols containing a large amount of volatile solvents such as gasoline or glycols to reduce viscosity making them suitable for coatable lacquers. For paper or textile substrates, plastisols are applied by rotary screen-printing techniques to produce flocked products such as tarps, artificial leather, and floor and wall coverings.
The Global PVC plastisol Additives market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Patcham Pat-Add Additives – Patcham Pat-Add Additives include wetting and dispersing agents, air release agents, defoamers, viscosity depressants and foam stabilizers. The range of additives are individually formulated to support production processes, solve problems/issues, and enhance material properties.
Plastisol based automobile coatings and seam sealers meet rigid standards set by various automobile manufacturing companies. A very important requirement for plastisol coatings is that they be lightweight.
As plastisol manufacturers strive for lighter and hence more fuel efficient vehicles, hollow glass microspheres has become a crucial part of the plastisol formulations as key raw material filler.
PVC Plastisols Additives being in liquid form can be sprayed on molds or parts . Thicknesses of up to 50 mil (1.3 mm) can be obtained in a single pass on a vertical panel. The sprayed parts are heated and cooled. Multiple passes are made to increase the thickness.
