Product description

Self-welding silicone from BIW is a highly functional solution for fast and secure sealing, insulation or repair – without any additional aids. The specially formulated silicone does not adhere to other materials, but bonds permanently to itself through pure material fusion.

Whether as tape, cord or in special shapes – the product is frequently used in electrical engineering, automotive engineering, household appliances or in the sanitary sector. It can also be used to reliably seal temporary connections in production or service.

The silicone base is resistant to moisture, UV radiation, oil, many chemicals and extreme temperatures. This makes the material particularly suitable for outdoor use or industrial environments – safe, flexible and efficient.
