LEAFLET TEX for recycling cross-linked polymers The Japan Steel Works, Ltd. Plastics Machinery Business Division Case 1: Breaking through shear stress Feed materials are refined by mixing screws then depolymerized by compressing and shearing effect. Crushed material Abstract Cross linked polymers such as thermoplastic insulator, tire or synthetic rubber materials are mostly incinerated or landfilled as they are hard to melt and reuse for molding again. To improve sustainability of plastic material use, JSW developed extrusion technology to recycle cross-linked plastics and rubber by using TEX. Recycled pellet Feature ・ Continuous cross-link breaking by twin screw extruder ・ High quality recycled pellets by dual-bar screen changer ・ Stable production by precise polymer temperature control ・ Smooth depolymerization by multiple additive injection ・ Waste collection by devolatilize and dewater equipment Case 2: Breaking by liquid additives Injected additives help to dissolve materials and promote depolymerize process. Crushed material Liquid additives Process TEX can control for multiple parameters for efficient cross-link breaking.
