Corroline+ is built around a unique PTFE hose liner design, which has a slightly rippled smooth bore inside, but convoluted outside to generate excellent flexibility combined with "hoop strength".
Corroline+ hose is fire resistant, and this video shows a fire resistance test. The Corroline+ hose withstood 1100 degrees Celsius for 15 minutes. During the test, the hose was flexed and vibrating too.
