Rubber mix – the mix which is not vulcanized like solid plasticine, after a stage of curing gets technical characteristics according to state standard specification or TU. This material has the difficult chemical composition keeping technological properties after thermal influence. Flexibility resistance to wear, thermal stability and other parameters depend on mix brand.
It is possible to buy crude rubber maslobenzostoyky (group III) of more than 50 brands. List of several most widespread brands: NO-68, 3826, 3825, 7B - 14 Are used they for production rubber, including – rubber-metal, the products made by method of molding, not molding and shpritsovaniye. Details from these raw materials can work in air, oil, water environments, with ethyl alcohol, different types of fuel. It is used for motionless or restrictedly mobile knots and motionless connections.
Crude rubber mix NO-68. The NO-68 brand is a maslobenzostoyka. average hardness crude rubber with a hardness indicator – 55 – 70 on BLINDERS. Conditional durability of this material makes 9,0 MPas, a temperature operational interval for products of this rubber mix –-50 – +100 °C. The relative lengthening for NO-68 determined by norms of standardization – 255%. Such type of crude rubber serves as initial raw materials for sealing and various other RTI.
Rubber mixes of the MBS brands . These materials possess the raised maslobenzostoykost. Brand 3826 has the hardness of 60-75 units of Shor, durability – 7.8 MPas at relative lengthening – 300%. Crude rubber 3826 can shpritsevatsya, be formed and kalandrovatsya. Mix rubber 3825 – firmer – 80 – 100 Blinders "A" and stronger – 9,8 MPas with smaller relative lengthening – 120%. For both brands – 3836 and 3825 – working temperatures –-30 – +100 °C.
Mix 7V-14 an average maslobenzostoykost hardness - from 70 to 85 c.u. of Shor, for production of the rubber products which are operated in different climatic conditions with temperatures of working environments, an interval-45 – +100 degrees Celsius. The standard determines durability level for this rubber – 9,8 MPas, hardness - within 70 – 80. Relative lengthening – 160%.
