EPE foam machine, also known as pearl cotton foam machine, is specialized industrial equipment designed to produce EPE foam—a lightweight, flexible, and shock-absorbing material with excellent thermal insulation, sound insulation, and chemical resistance. The production process involves melting LDPE (Low-Density Polyethylene) resin, mixing it with a foaming agent (typically butane or pentane), extruding the mixture into a foam structure, and cooling it to form continuous EPE foam sheets or profiles. EPE foam is widely used in packaging (e.g., electronic product cushioning, fragile goods protection), construction (e.g., thermal insulation layers, soundproof panels), automotive (e.g., interior cushioning, door panel insulation), and daily necessities (e.g., yoga mats, children's play mats). EPE foam making machine is categorized by output, foam thickness, and automation level, with fully automatic lines being the mainstream choice for large-scale production.
