Crude rubber 7v-14, 3826, 1347, and also production of different types of rubber mix (crude rubber).
Rubber mixes can be kalandrovanny and valtsovanny. They are made according to various normalizing documentation. Rubberizing a manzhetok of zolotniks, productions of footwear, various laying, details for aviation, automotive, food, other industry is used as a part of glues, sealants, sealants, for compression molds, electroinsulating materials, repair and joining of RTI, opressovochny gumming and a manual facing of instrument elements. On the technical indicators they can be usual, heatresistant or frost-resistant, steady against influences of acids, alkalis, gasolines, oils, other active agents. Any products from so-called crude rubber have elasticity, explosive durability, ability to restoration after a bend, wear resistance.
It is possible to buy crude rubber valtsovanny maslobenzostoyky (group III) of several brands here: NO-68, 3826, 3825. Also available – 7V-14, etc. They are used for production rubber, including – rubber-metal, the products made by method of molding and which are not formed. Details from these raw materials can work in air, oil, water environments, with ethyl alcohol, different types of fuel, are applied for motionless or restrictedly mobile knots working at static loadings.
Crude rubber mix NO-68. The NO-68 brand is restrictedly a maslobenzostoyka. It is medium-hard crude rubber with a hardness indicator – 55 – 70 Blinders "A". 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. The rubber mix NO-68 is formed and kalandrutsya.
Rubber mixes of brands 3836 and 3825. 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 – 90 Blinders "A" and stronger – 9,8 MPas with smaller relative lengthening – 120%. For both brands – 3836 and 3825 – working temperatures –-30 – +100 °C.
Brand of crude rubber mix 7V-14. Crude rubber 7V-14 is a material with an average maslobenzostoykost of the increased hardness - from 70 to 85 c.u. of Shor. It is applicable 7V-14 for production of the rubber products which are operated in different climatic conditions with temperatures of the working environments which are not going beyond an interval-45 – +100 degrees Celsius. The standard determines durability level for this rubber – 9,8 MPas, hardness - within 70 – 80. Relative lengthening – 160%.
