Saint Gobain CHR® 2255 Series Tape
The Saint Gobain CHR® 2255 Series is crafted for high-temperature stability and chemical resistance, providing reliable insulation for heavy-duty applications. With a high-modulus PTFE backing and silicone adhesive, this tape ensures non-stick surfaces and dielectric strength in harsh environments. Capable of withstanding temperatures up to 500°F, the 2255 Series excels in applications like thermal insulation, chemical barriers, and gasketing, offering dependable performance across industrial, aerospace, and automotive applications.
Applications include: High temperature electrical insulation and gasketing, chute linings, thermal insulation in high-wear areas, and chemical-resistant barriers.
- Low elongation
- Chemically inert
- Low coefficient of friction
- Anti-stick
- High dielectric strength
- High tensile strength
