PTP turbo blankets and wraps are nonflammable. However, if flammable materials, such as oil or gasoline, are allowed to cover or saturate the material, a flame may be produced. Please make sure there are no fluid leaks within the engine compartment that could allow the turbo blanket or wrap to become contaminated with such liquids. PTP turbo blankets and wraps are not designed to be removed and replaced multiple times after being heat cycled through normal usage. The material becomes less pliable after heat cycling and thus, may not be as easily re-configured. (due to loss of flexibility) This loss of flexibility is normal, and does not adversely affect the material's heat insulation properties. PTP is not responsible for damage caused by improper usage of our products.
