Features and functions of lab twin screw extruder
A lab twin-screw extruder is a type of extrusion machine specifically designed for research, development, and small-scale production in laboratory settings. It is a scaled-down version of industrial twin-screw extruders used in larger manufacturing facilities. Here are some key features and aspects of a lab twin-screw extruder: Overall, lab twin-screw extruders play a crucial role

Polyethylene terephthalate (PET)
Polyethylene terephthalate (PET), with the chemical formula (C10H8O4)n, is obtained by ester exchange of dimethyl terephthalate with ethylene glycol or esterification of terephthalic acid with ethylene glycol to synthesize dihydroxyethyl terephthalate, followed by polycondensation. It is a crystalline saturated polyester, a milky white or light yellow, highly crystalline polymer with a smooth and glossy surface.

Low density polyethylene (LDPE)
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

Types and price range of lab twin-screw extruders
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

Linear low-density polyethylene (LLDPE)
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

General purpose polystyrene (GPPS)
Polystyrene, referred to as PS. PS is a thermoplastic non-crystalline resin, which is polymerized from styrene monomers. It can be polymerized by a variety of synthetic methods. The main methods used in industry are bulk polymerization and suspension polymerization. PS is mainly divided into general-purpose polystyrene (GPPS, commonly known as transparent polystyrene), high-impact polystyrene (HIPS,
