Pretreatment Effects of Conventional and Reactive Extrusion on LLDPE Waste Pyrolysis

Polymer Engineering &Science, EarlyView.
Schematic overview of the pyrolysis study using original and pretreated LLDPE waste samples. Pretreatment was performed via twin‐screw extrusion at 450°C: without additives (REX), with peroxide (REX‐RO2), or with polypropylene (REX–PP). All four samples underwent pyrolysis at 450°C–475°C for 15–45 min.

Comparing the Applicability of State‐Of‐The‐Art Photopolymer Injection Molds Printed by Multi‐Material Jetting and High‐Performance Digital Light Processing

Polymer Engineering &Science, EarlyView.
The workflow of comparing state‐of‐the‐art photopolymers in rapid tooling. ABSTRACT Additive manufacturing (AM) introduced the concept of layer‐by‐layer manufacturing, which allows the fast and direct production of parts. Additive technologies are also hybridized with conventional polymer processing technologies.

Synergistic Network Formation in SBR/ANF Composites: GMA Bridging and Electron‐Beam Crosslinking for Enhanced Strength and Damping Control

Polymer Engineering &Science, EarlyView.
Styrene‐butadiene rubber/aramid nanofiber composites interfacially reinforced with glycidyl methacrylate via electron beam irradiation. ABSTRACT Styrene‐butadiene rubber (SBR) is widely used in tire and damping applications, yet its reinforcement with polar nanofillers is often limited by weak interfacial adhesion in nonpolar matrices.
