Feb 26, 2025 · We prioritize client success by not just delivering a unique variety of custom expandable polystyrene resins (EPS), but by establishing long-term partnerships. The most widely used resin in the industry is polystyrene-type gel resin. EPS is known for its excellent thermal insulation, shock absorbency, and resistance to moisture. Expanded Polystyrene (EPS) EPS is produced by using steam to expand and fuse polystyrene beads via a variety of manufacturing processes creating a closed-cell structure that contains air, making it ideal for a variety of applications including construction, packaging, shipping, and food storage. Mar 14, 2005 · The method could not only be applied to the vibrational spectroscopic encoding of the polystyrene resin bead, but also could theoretically be extended to the encoding of other polymer resin beads, especially those polystyrene-based resin beads reported by Fenniri and co-workers [10], [11]. Bio-Beads SM-2 Resin has a high surface area for adsorbing organics with MW <2,000 from aqueous solutions. The resin employs pentane as the major blowing agent and never uses freon gas depleting the ozone layer. Jun 28, 2018 · The cross-linked polystyrene functionalization is largely dependent on the bead diameter. Polystyrene beads are often mistakenly referred to as STYROFOAM™ beads. STYROBAR® (STYROBAR 16 CCMC# 13217-L, STYROBAR 22 CCMC# 13218-L, STYROBAR 28 CCMC# 14033-L) STYROBAR® is an Expandable Polystyrene Insulation (EPS) manufactured by AMC Foam Technologies Inc.
