Linear low-density polyethylene (LLDPE) is a molecular structure formed by copolymerization of ethylene and a small amount of α-olefin on the main chain of linear ethylene with very short comonomer branches. Linear low-density polyethylene is a non-toxic, tasteless, odorless milky white particle with a density of 0.918~0.935g/cm³. Compared with LDPE, it has higher softening temperature …
Twin-screw extruders are commonly used in various industries, including the polymer, food, and pharmaceutical industries, for the compounding, mixing, and extrusion of materials. There are several types of lab-scale twin-screw extruders available, each with unique features and capabilities. Here are some common types of lab twin-screw extruders: Co-Rotating Twin-Screw Extruders: Counter-Rotating Twin-Screw Extruders: Self-Wiping Co-Rotating …

Low-density polyethylene, also known as high-pressure polyethylene (LDPE), is the lightest variety of polyethylene resin. It is milky white, tasteless, odorless, non-toxic, and matte waxy particles. It has good softness, extensibility, electrical insulation, transparency, easy processing, and certain air permeability. It has good chemical stability and is resistant to alkali and general organic solvents. Overview …
