Rubber slabs GOST 7338-90

Used for manufacture details, serving for compression of fixed joints, to prevent friction between metal surfaces, to get segregate dash loading in machines and aggregates or  used  to make separators and floorings.

Depending on purposes and way of producing, slabs have differences in:

Classes:

- 1 class: slabs used for compression of kinks under the pressure after 0,1MPa;

- 2 class: slabs used for compression of kinks under the pressure up to 0,1MPa;

Kinds:

 “Ф” – moulded slabs, producing by vulcanization on cure presses;

 “Н” – unmoulded slabs, producing by vulcanization in boilers, and on cures of continuous working;

Types:

I – rubber slab;                                                         

II – rubber slab with tissues.

Firmness grade:                                                                              

“М” soft;                                                                                           

“С“–average;                                                                                     

“Т” – increased firmness.
