Specifications Composition: 99.6% PTFE < 0.4% Pigment Color: Blue Length: 1429" Thickness: 0.0035" +/- 10% Density: 0.8g/cm3 Elongation: >100% Tensile strength: 15N / mm2 Pressure rating: Mill-Rose Blue Monster Thread Sealing Tape has been used to seal fittings carrying water and oil at pressures up to 10,000 PSI or 69,000kPa Note: Pressure ratings are relative to the quality and torque of the fittings and the amount of tape used. Temperature range: -450°F to +500°F (-268°C to +260°C) PTFE is completely stable up to +500o F or +260°C. Decomposition is slow up to 750°F or 400°C. Although decomposition will occur on contact with naked flames.
