Product Description
The high temperature coated fiberglass fabric is designed for flexible ducting, thermal sealing, and expansion joint applications in systems exposed to elevated temperatures, vibration, and chemical environments.
Manufactured by BSTFLEX, this material is produced from fiberglass cloth coated with PTFE (fluoroplastics) or silicone rubber, forming a durable belt or fabric sheet suitable for temperature-resistant ducts and expansion joint compensators.
The coating enhances resistance to heat, chemicals, moisture, and abrasion while maintaining fabric flexibility required for movement absorption.
Woven fiberglass fabric
Non-combustible and heat resistant
Provides mechanical strength and dimensional stability
Excellent chemical resistance
Low friction surface
Suitable for corrosive or aggressive gas ducts
High temperature flexibility
Resistant to moisture, ozone, and aging
Suitable for dynamic expansion joints
These coating options allow selection based on operating temperature, media, and movement requirements.
Flexible connection for duct expansion joints
Absorbs thermal expansion and vibration
Seals hot air and gas duct systems
Provides thermal and chemical resistance
Protects duct systems from mechanical stress
The fabric is designed for expansion joint and ducting applications, not for pressure containment.
