CYG's heat-shrink tubing meets a variety of requirements for harsh applications. For example, the medium-thickness wall tubing in my hands with halogen-free and good UV-resistance can provide electrical insulation, mechanical protection, and environmental sealing in applications such as wire connectors and related accessories. Our long-term reliable tubing is great even in harsh climates and polluted environments. Because of that, it is applicable to public facilities such as electric power facilities, public lighting, and public transportation.
