A compatibility stability idiosyncrasy of diisodecyl adipate (DIDA) could pose a troublesome problem. A PVC plastisol formulated with DIDA and fused in an oven for 10 min at 175 C will exude but if the fusion period is lengthened to 0.5 h, it will not. One explanation is the dielectric constant of DIDA is below A it should be incompatible and therefore exude. However, upon extensive heating in air this oxidation-susceptible plasticizer builds up peroxides, undergoes chain scission and weight loss, and changes in compatibility. As shown in Table I, if the oxidation phenomenon is negated in per se DIDA by the presence of an antioxidant, bisphenol A, the plasticizer remains unchanged in dielectric constant and predictably would be incompatible (20). [Pg.618]

The manufacture of epoxy stabilizers begins with soya and linseed oils or oleate and other unsaturated fatty acid esters. When epoxidation is incomplete, residual unsaturation remains, leading to poor compatibility-stability. This results in exudation on products in the marketplace. Makers of epoxldized fatty acid esters strive to prevent such failure by ensuring more complete epoxidation and supplying products with the lowest possible iodine number. Vinyl formulators further protect themselves by diminishing the proportion of epoxidized stabilizer to an amount ca. 3% while maintaining plasticizer concentration at ca. 35%. [Pg.628]

Low thermal stability (thermal destruction initiation interval is within 190-210 °C). Require combining with thermal stabilizers. Compatible with plasticizers. [Pg.32]

Cellulose acetate-butyrate (CAB) has several advantages in properties over cellulose acetate lower moisture absorption, greater solubility and compatibility with plasticizer, higher impact strength, and excellent dimensional stability. CAB used in plastics has about 13% acetyl and 37% butyryl content. It is an excellent injection-molding material (Tenite Butyrate by Kodak, Cellidor B by Bayer). [Pg.511]

Chlorinated diphenyls (PCB) n. Range of chlorinated hydrocarbons varying in properties from very liquid plasticizers, through thick syrups to solid resins. They are characterized by excellent compatibility, stability, and absence of free acidity, high toxicity, and non-flammability. [Pg.185]

Compatibility of plasticizers n. Miscibility and stability of one or more plasticizers to plastize a polymer or resin. [Pg.214]

Plasma processing technologies ate used for surface treatments and coatings for plastics, elastomers, glasses, metals, ceramics, etc. Such treatments provide better wear characteristics, thermal stability, color, controlled electrical properties, lubricity, abrasion resistance, barrier properties, adhesion promotion, wettability, blood compatibility, and controlled light transmissivity. [Pg.434]
