Plastisol test methods

Standard Test Method for Apparent Viscosity of Plastisols and Organosols at Low Shear Rates by Brookfield Viscosity, ASTM D1824, Am Soc. Testing and Materials. 2002. [Pg.375]

The first successful static firing of plastisol propellant took place late in 1950 as part of a broad program conducted by Atlantic Research Corp. to investigate and evaluate plastisol propellants and methods for their manufacture (16). Major attention was directed to poly (vinyl chloride), cellulose acetate, and nitrocellulose, although other polymers were tested for their suitability (17). Patent applications were filed for plastisol propellant compositions and manufacturing processes, based on poly(vinyl chloride) (PVC) (19) and on nitrocellulose (18). The commercial availability of dispersion grade PVC enabled work with this resin to advance rapidly. The balance of this paper is devoted to a discussion of PVC plastisol propellants and their manufacture. [Pg.45]

Hotbench test n. A method of determining gelation properties of plastisols, employing a bar or plate whose temperature rises from one side to the other ( temperature-gradient plate ). The sample is spread on the bar... [Pg.500]

In case of printing paste, more than 5% w/w volatile organic compounds (VOCs) should not be permitted. These include acrylates, styrene monomers like acrylamide, butadiene, polyols, acrylonitrile, formaldehyde, hydrocarbons, ahphatic hydrocarbons (C10-C20), ammonia, etc. MSDS for printing formulation has to be supplied, and the testing can be done by solvent extraction and GC-MS methods. There is a restriction on the use of plastisols in printing binders and restricted phthalates including PVC. The threshold limit is 0.1%. [Pg.188]
