Self-Fusing Silicone Tape

Self-fusing silicone tape from Freudenberg Sealing Technologies is made of a specially formulated silicone rubber capable of fusing to itself to create a flexible, homogeneous barrier. The tape starts to tack within seconds, forms an air and water tight seal within minutes, and permanently fuses to itself within 24 hours.

Self-fusing silicone tape contains no adhesive, which makes for residue-free installation and removal. And unlike traditional adhesive based tapes, it can be applied to surfaces that are wet or dirty without any impact on performance. It has excellent dielectric strength, ozone resistance, high and low temperature stability and moisture resistance.

Applications

• Insulation for electrical systems – Protection for motor and generator coils and leads without any residue left behind on removal.
• Harness wrapping and wire bundling – Meets Class H insulation requirements. Easy applications and removal.
• Splicing, terminating, and bonding – Ideal field repair system. Significantly easier and cleaner application than traditional tapes and potting compounds.
• Aircraft Applications – Flame retardant versions available to secure insulation to hot air ducting.
• Automotive Applications – Easily installed as a battery weather wrap to prevent corrosive buildup on terminals.

Values to the Customer

• Quick Acting – Starts to tack instantly and forms a permanent bond within 24 hours
• Sealing – Forms a homogeneous, void free, air and water tight seal.
• No adhesive – Can be applied to unclean surfaces and leaves no residue behind.
• Protects – Against UV, ozone, fungus, salt water, fuels, oils, coolants, acids, and cleaners.
• Flexibility – Remains flexible even when exposed to abrasion and temperatures down to -65°C.
• Insulation – Provides up to 8000 Volts (at 0.50mm thick).
• Fire and heat resistance – Can be made to meet fire resistance and fire proof specs, and can function without melting above +260°C.
• Electrical advantages – Silicone tape has superior arc and corona resistance.
• Can be custom designed to meet a wide range of applications.

Features And Benefits

Tape Cross Sections

Rectangular Tape: This tape has a uniform thickness across the cross section.  It is ideal for applications where a smooth, even outer layer of tape is not required.  It most resembles traditional electrical tapes.

Triangular Tape: This tape has a tapered triangular cross section that is thicker in the middle and has a difference colors cross section running down the center line.  It is ideal for applications where the thickness of the coating must not have any visible overlap.

Sinusoidal Rectangular Tape: This tape has a uniform cross section with a continuous sinusoidal glass yarn encapsulated inside.  This provides the tape with increased tear resistance and controlled elongation between 15% and 25%.  This tape is ideal for applications requiring both excellent mechanical characteristics, and the ability to conform to complex shapes.
