Fiberglass Woven Tape for Electrical Apparatus Manufacturing
High Temperature Insulating Tape for Motors, Starters, Generators and Transformers
1200°F / 648°C Continuous Exposure:
Higher Intermittent

DeltaGlass high temperature tape for electrical apparatus manufacturing is designed for motors, generators, starters and transformers, and is heat, flame and fire resistant.  Fiberglass (fibreglass or glass-fibre) woven tapes are fabricated from high quality type E fiberglass that will not burn and will withstand continuous exposure to temperatures of 1200°F / 648°C.

These high temperature tapes provide protection of industrial wires, cables, hoses, tube and pipe and also provide thermal insulation and personnel protection. Also used as a gasket or seal. 

This material resists most acids and alkalis and is unaffected by most bleaches and solvents.  It is flexible and conformable.

Benefits of our High-Temperature Fiberglass Heat Protection Products

Fiberglass offers excellent heat resistance, retaining more than half of its room temperature tensile strength at 675°F / 357°C, and more than 25% at 875°F / 468°C.  It begins to soften at 1500°F / 815°C and melts near 2050°F / 1121°C. Non-combustible and excellent thermal conductivity to dissipate hot spots; high resistance to chemicals and unaffected by UV light.
