FST6030SI
Volsun
FST6030SI is a self‑fusing silicone rubber tape that provides reliable electrical insulation, flame retardancy and environmental protection in demanding conditions. Its surface is non‑sticky, but once stretched and wrapped, it self‑amalgamates into a homogeneous layer that offers airtight, waterproof and insulating performance.
Operating in a temperature range from approximately –60°C to +180°C, FST6030SI offers tear, abrasion, UV, ozone and anti‑aging resistance. It is suitable for electrical power cable joint insulation, bare conductor protection, switch cabinet copper busbar insulation, and other scenarios where durable, flame retardant sealing is required. The tape can be customized in size, color and packaging according to project needs.

Wipe the surface of the object to be protected, tear off the isolation film, and wrap half of the
self-adhesive tape on the object to be protected
Finish installation
Before installation, the surface of the object to be protected must be cleaned, free from dirt and debris, so as not to affect the installation and use
When tearing off the film and attaching it to the protected object, a small amount of tearing off the film is required. Too much film tearing at one time will cause wrinkles and stick to impurities during use, which will affect the use
When pasting, one-half overlap is required to ensure the protective effect of the product
The environment should be kept as clean as possible during use to prevent impurities from sticking to the tape and affecting the adhesive force
FST6030SI is a high temperature resistant, flame retardant silicone rubber self‑fusing tape used for electrical insulation and sealing protection.
No. FST6030SI only adheres to itself and leaves no sticky residue on the wrapped surface.
FST6030SI operates from approx. –60°C to +180°C.
Yes. FST6030SI meets flame retardant performance of UL94 V‑0.
It is typically used for electrical power cable joint insulation, bare conductor protection, switchgear busbar insulation and environmental sealing of electrical connections.
Yes. Its anti‑aging and UV resistance properties make FST6030SI suitable for outdoor installations.
