FIELD: polymer materials. ^ SUBSTANCE: invention relates to mineral oil-containing fluoroelastomer compositions exhibiting improved flowability when the latter are processed into corresponding products. To obtain these products, a composition containing fluoroelastomer, curing system, and mineral oil is provided, which is then processed to form fluoroelastomer product and cure fluoroelastomer composition, wherein mineral oil is partially adsorbed on a carrier. Product is formed using a technique selected from extrusion, injection molding, transfer molding, and combination of these techniques. Mineral oil is used in cured fluoroelastomer composition as process additive improving flowability of composition and facilitating removal of cured product from mold. Composition of invention is entirely free of vegetal-origin wax or contains it in amount less than 2 wt parts per 100 wt parts fluoroelastomer. ^ EFFECT: improved workability of composition. ^ 21 cl, 27 ex |
