PFA heat shrink tubing is a high-performance fluoroplastic heat-shrink tubing primarily made from perfluoroalkoxy resin.
This material offers excellent high-temperature and chemical resistance, non-stick properties, and electrical insulation.
Upon heating, PFA heat shrink tubing shrinks radially, conforming tightly to the object it wraps, forming a protective layer that provides sealing, insulation, and mechanical protection for wire and cable joints, connectors, electronic components, and other parts requiring protection.
