Asbestos-steel sheet LA-1, LA-1A and LA-2 (krengelite) (ЛА-1, ЛА-1А и ЛА-2 (кренгелит))

Asbestos-steel canvas (asbestos-steel sheets) LA-1, LA-1A and LA-2.
They are used for cutting gaskets intended for sealing the joint of two contacting surfaces: for sealing the joint between the head and the cylinder block of carburetor and diesel engines, for sealing the joints of exhaust systems with edging of working holes.

The products are efficient at temperatures up to -60°С, operate in a wide range of temperatures - up to 400°С, pressures up to 0.35 MPa and under the influence of various environs: gasoline, diesel fuel and their combustion products, automotive and diesel oils, coolants, water, antifreeze with the addition of anti-corrosion additives.

Sheets are made of a perforated frame covered on both sides with asbo-latex paper.

The surface has a graphite coating based on synthetic rubber.
