About PVC Plastisol

General Description:

Plastisols are fluid forms of vinyl plastic molding and coating compounds which make a variety of unique molding processes available. Plastisols are 100% solids. Most plastisols used are low to medium viscosity materials (having a viscosity between 1000 and 10,000 centipoises at 2.5 rpm on the Brookfield Viscometer). Some PVC plastisols used in the textile screen printing industry have viscosities as high as 4 million cps. at 0.5 rpm. Properties will vary depending on the application the plastisol will be used for.

Plastisols are very versatile, offering numerous application and processing possibilities. Cured (or fused) plastisol has the same basic physical properties commonly associated with other vinyls: flexibility, toughness, outdoor stability, abrasion and chemical resistance. Plastisols can be custom formulated to fit your application and processing needs.

Plastisols are available in formulations of hardnesses ranging from the Shore D (very hard compounds) to Shore 00 (very soft-soft plastic worm types). Many different properties can be incorporated into plastisols. Some of the available properties are low temperature flexibility, non-marring, nonflammable, acid resistance, abraision resistance, slip, as well as many others.

Processing of PVC Plastisols:

'Cure' (or fusion) of plastisols is a physical change of the resin being solvated by the plasticizer on heating. The fusion process changes the plastisol from a liquid to a solid state and brings about ultimate physical properties. As complete fusion is reached clarity, surface gloss, tensile and tear strength reach their maximum. Fusion is completed at approximately 350 to 400°F. Usually processing is done between 350° and 500°F to speed heat transfer. The time required to reach fusion is a function of the temperature and thickness of the material. When the heating process is complete the material is cooled. Through this curing process the plastisol transforms from a liquid material to a solid material with good physical properties.

There are many different curing methods which include oven, molten salt, microwave (for very soft compounds), hot plates, and radiant heat to name a few.

Physical Properties of PVC Plastisol: 

  • • Chemical Resistance: to acids, alkalines, detergents, oils and some solvents.

  • • Tensile, Elongation, Tear: Tensile (psi) 200-4000; Elongation 100-600%; Tear 100-500 #/in.

  • • Low Temperature Flexibility: to -65°F

  • • Abrasion Resistance

  • • Extraction Resistance: to certain oils, mild detergents, etc.; this varies with temperature.

  • • Adhesion to metal/ demoldable

  • • Electrical Properties (Antistat)

  • • Flame retardant

  • • UV/ Weatherability: Good to excellent, usually at least 10 years.

  • • High Impact Strength

  • • Heat Distortion

  • • Mass solid density: 7.9 to 20.5 #/gallon

  • • Foam Density: Chemical Foam to 10 #/ft 3

  • • Surface appearance: Glossy, Textured, Flat

  • • Hardness: 10 Shore00 to 80 ShoreD

  • • Toxicity: Can be formulated with FDA approved materials

Applications:

Dip Molding / Dip Coating: Used when coating metal parts or making parts (caps) to be put on to other substrates that can't take    the heat. A "hot dip" would use a heated substrate, such as metal, while a "cold dip" would use a cold substrate such as a supported glove. This process is used for tool handles, wire racks, supported and unsupported gloves and miscellaneous parts.

Foam Molding: Used for such products as athletic padding, mats, life preservers, auto gaskets. These can be dip molded, slush molded, casted, roll coated, etc. with many different textures.

Slush Molding: This process is used when part of the mold is open. Used for such products as boots, toys, automotive parts, etc.

Rotational Molding: This process is for molding closed parts such as beach balls, squeeze toys, bicycle seats, etc.

Coatings: Strippable coatings, misc. industrial coatings, food can coatings, etc.

Casting / Molding: Used when making such products as: toys, bottle cap liners, gaskets, floor mats.

Adhesives: Used when making such products as auto air and oil filters, hood and trunk lining.

Roll Coating: Used to apply a layer of Plastisol to fabric, release paper, carpet, coil coating, unsupported film, etc.

Spray Coating: For use when coating vertical pieces and hard to coat pieces.

Screen Printing: Used when Printing on textile and other substrates.
