PARONITE MASLOBENZOSTOYKY (PMB)
The paronite of maslobenzostoykiya of the PMB brand (or MBS paronite) is applied to production of the condensing laying which pressurizes motionless demountable connections of various mechanisms and units. Rubber rubber mixes with additive of asbestos fibers and special modifiers are a part of a paronite .
Form of release of a paronite of MBS – sheets of 0,4 - 3,0 mm dimensions from 500х500 mm to 1770х1000 mm. According to the additional arrangement at the manufacturing plant production of sheets of a paronite of PMB of the big sizes or ready laying according to the approved drawings of the customer is possible. If the sizes allow, laying from a paronite of the PMB brand is made by a cutting down method of an integral leaf. If the amount of laying from a paronite of GOST 481 - 80 exceeds preparation dimensions, glue seams "with an overlap" and "larkspur" connections are allowed.
The paronite of PMB and product from it are issued in cold, moderate and tropical climatic modification. For tropical execution the corresponding fungicides are added to structure of a paronite.
