NOVELTY - Plastic beads comprise 100 pts. wt. synthetic resin raw material, 30-50 pts. wt. flexible polyurethane foam, 10-20 pts. wt. functional mixture comprising antibacterial agents, ceramics, or zeolites, 0.1-1.0 pts. wt. graphene, 0.01-0.3 pts. wt. powder mixture and 1-3 pts. wt. chemical foaming agent. The synthetic resin raw material is poly vinyl chloride and poly ethylene. The graphene is a spherical graphene powder having particle size of 50-170 nm. The powder mixture is a mixture of copper powder and stainless steel powder in mass ratio of 4:0.1-2.0. USE - The plastic beads is useful in pillow and bedding, preferably in hospitals. ADVANTAGE - The plastic beads: retains original volume even after washing; is convenient to use; reduces pillow weight; has good chemical safety, thermal conductivity, electrical conductivity, and antibacterial properties; is easy to wash; and has excellent restoring force; can be used repeatedly hygienically; provides comfortable sleeping environment; and prevents contamination by sweat.
