Mixtures of elastomers, so-called blends, combine the properties of their respective basic components. By optimizing the mixing ratios, new technically relevant quality characteristics are generated and further application areas are developed. This necessarily applies also to blends made of natural rubber (NR) and styrene butadiene rubber (SBR), which combine the high elasticity of natural rubber as well as abrasion resistance and tensile strength of the styrene butadiene rubber, inclusive its good aging resistance, in one product.
RCT Reichelt Chemietechnik offers proven plates made of NR/SBR blends from its comprehensive range of semi-finished products, which can be used at temperatures from approx. -30 °C to +70 °C. Premium products are white NR/SBR plates, which meet the strict requirements of the US Food and Drug Administration (FDA-CFR 177.2600) in conjunction with the BgW guidelines, XXI, Cat. 1. They are therefore explicitly approved for food applications and supplied by RCT Reichelt Chemietechnik as NR/SBR food plates in graded thicknesses between 1 mm and 6 mm and standard dimensions of 700 mm x 700 mm as well as 1,400 mm x 1,400 mm. The shore hardness A of the material is 45°, its density is 1.3 g/cm3.
RCT Reichelt Chemietechnik offers black colored NR/SBR plates with narrowly tolerated cotton inserts for laboratory and industrial applications. Due to their stratified structure such NR/SBR plates are mechanically highly stressable.
NR/SBR plates with one cotton insert each are available in thicknesses from 1.5 mm to 6 mm. The material with the density of approx. 1.5 g/cm3 has a shore hardness A of 70° ±10. Also available are NR/SBR plates with two inserts in thicknesses between 3 mm and 6 mm with the same shore hardness A. The standard dimensions for both cotton-reinforced qualities are 600 mm x 600 mm and 1,200 mm x 1,200 mm.
