Abstract: Pre-expanded styrene polymer particles, which may contain one or more pre-expanded styrene polymer beads, are coated with sufficient water glass so that the particles, when dried to a reversible, tack-free pourable state, comprise from about 30% to 80% styrene polymer solids. The particles may be shaped into a desired article configuration and then dried to a tack-free state, the particles adhering together through the water glass, and the resulting article having a bulk density of from about 1.25 lbs. to 3 lbs. per cubic foot. The water glass or the pourable particles may be treated to decrease alkalinity and to cause irreversible precipitation of water glass solids, rendering the final product essentially waterproof.

Abstract: A rubber molding composition comprising cured rubber scrap (as from automobile tires), a liquid, sulfur-curable polymeric binder, and a curing agent for the polymeric binder. The composition employs from about one to about five parts by weight of the polymeric binder per 100 parts by weight of the scrap rubber. The thus treated rubber scrap may be used in large proportions as a filler or extender for uncured rubbers.
Abstract translation: 一种橡胶模制组合物，其包含固化的橡胶废料（来自汽车轮胎），液体，硫可固化聚合物粘合剂和用于聚合物粘合剂的固化剂。 该组合物每100重量份的废橡胶使用约1至约5重量份的聚合物粘合剂。 如此处理的橡胶废料可以大量用作未固化橡胶的填料或增量剂。
