SFG-Silicone-coated fiberglass sleeving (fiberglass inner layer with silicone rubber outer coating)1.5kV~7kV

-50~+200 Fireproof Uvproof CRUS RoHS

Applications

The fiberglass silicone sleeving is braided with alkali-free fiberglass yarn, coated with silicone resin (silicone rubber) on the outer layer, and treated at high temperature and complies with UL, RoHS, REACH, and halogen-free standards.
Multiple voltage grades are available to meet various application requirements: 1500V, 2500V, 4000V, and 7000V, providing reliable insulation performance across various conditions.
G-APEX Silicone Fiberglass Sleeving delivers robust protection for your equipment. Whether in high-temperature, high-voltage, humid, or chemically corrosive environments, it ensures the long-term operational stability of the equipment, reducing failure risks and maintenance costs.
This sleeving offers excellent insulation, high-temperature resistance, flame retardancy (self-extinguishing), and flexibility, it's an ideal choice for all kinds of electrical machinery (widely used for Class H and Class N insulation) and electric heating devices.


Typical Applications:

  • Household Appliances: electric heaters, lighting fixtures, televisions, etc.
  • Industrial Equipment: electronic instruments, motors, transformers, and other high-voltage devices
  • Automotive and EV(Electric Vehicle) Wiring Harnesses: providing superior insulation and protection
  • Special Environment Applications: aerospace, military, and other fields requiring high-temperature and insulation protection
