RAIL GREASE MS-27 and MS-27z
- - critical load (Pcr) (921N);
- - welding load (Pw) (over 4381N);
- - a better viscosity-temperature characteristic.

The rail grease is packed either in plastic barrels of various capacity. Nominal net weight of the packed product is 50 kg) or metal drums (nominal net weight of the packed product is 40 kg.
The rail grease is shipped in covered vehicles in accordance with the corresponding transportation rules, without limitations of distance and speed, with measures taken to prevent damage to containers or moisture ingress to the product.
ХThe grease is stored in sealed original containers in naturally ventilated warehouses, under conditions excluding moisture condensation on container’s surface.
