Introduction to PTFE Material

PTFE Heat-Shrink Tubing (also known as Teflon® Heat-Shrink Tubing) is a high-performance heat-shrink sleeve made from polytetrafluoroethylene (PTFE). It exhibits exceptional properties, including high-temperature resistance, corrosion resistance, excellent electrical insulation, and a low coefficient of friction. It is widely used in high-end industries such as electronics and electrical engineering, aerospace, chemical processing, and medical devices.

Control of Fluoroplastic Crystallinity

The crystallinity of fluoroplastics affects their transparency, mechanical properties, thermal stability, and processability: higher crystallinity enhances strength, heat resistance, and chemical stability but reduces transparency; conversely, lower crystallinity has the opposite effect.

Extrusion Process

Extrusion is a continuous manufacturing process in which materials such as plastics and rubber are heated and plasticized, then conveyed by a rotating screw through a die to form products with a constant cross-sectional profile. This process is characterized by high efficiency and operational flexibility.

Classification of Flame Retardants

Flame retardants for plastics are classified as follows: - By chemical composition: inorganic (e.g., hydroxides, oxides) and organic (e.g., halogen-based, phosphorus-based, nitrogen-based, intumescent); - By application method: additive-type and reactive-type; - By environmental compatibility: conventional halogen-based versus eco-friendly halogen-free types; - By flame-retardant mechanism: gas-phase, condensed-phase, and synergistic flame retardancy.
