Description

[0031] The invention is further illustrated by means of the following Figures:

[0032] FIG. 1 shows a heat protection lay-flat hose. It is prepared by cutting a sheet material comprising a polyester felt 1, an adhesive 2 and a PET sheet 3 having a deposited aluminum film on both sides thereof into two webs, and then providing them with ultrasonic welding seams 10 on the sides thereof. Such heat protection lay-flat hoses can be produced continuously and are suitable, in particular, for the insulation of ribbon cables.

[0033] FIG. 2 shows a heat protection circular tube.

[0034] FIG. 3 shows the structure of the material of said heat protection circular tube. A polyester felt 1 is bonded through adhesive layers 2 to an aluminum foil 4 and a PET sheet 3 with a deposited aluminum film. The material is shaped into a hose and closed by a ultrasonic welding seam 10. Such a material is suitable, in particular, for the protection of cooling water hoses.

[0035] FIG. 4 shows a heat protection bag.

[0036] FIG. 5 shows a side view of said heat protection bag.

[0037] This bag is obtained from a material as described for FIG. 3 comprising a polyester felt, an aluminum foil and a PET sheet with a deposited aluminum film, which are mutually bonded together by an adhesive. These are joined together and provided with a welding seam 10.

[0038] The heat protection bag according to the invention also has a lap 12 that can be closed by means of a stainless steel push button 11. This can be used, for example, for thermally controlling connectors in automobiles for supplying media for SCR catalysts.
