Whilst we have manmade or synthetic rubber produced from petroleum, around one-quarter of the worlds rubber comes from a natural source. Natural rubber is a vital agricultural product or commodity which is used in the manufacture of a wide range of products. Rubber plays a major role in the socio-economic fabric of many developing countries.
The ratings for these materials are based upon the chemical resistance only. Added consideration must be given to pump selections when the chemical is abrasive, viscous in nature, or has a Specific Gravity greater than 1.1. NOTE The materials shown below in BOLDFACE TYPE are used in the construction of Little Giant chemical pumps.

Chloprene rubber linings are suitable for desalination plants, sea water piping, lining for water box, site joints of CWP, vessels etc. Butyl Rubber Lining- Butyl rubber has excellent chemical resistance at high temperatures. These rubber linings are also very durable due to the inherent low vapor permeability.
It was first produced under government control between 1930 and 1950, which was used as a replacement for natural rubber. The basic monomers are butadiene and styrene, with styrene content approximately 23.5. About one third of the world output of SBR is used in tire production. SBR is mostly used in seals for non-mineral oil based brake fluid ...
The chemical compatibility data can be presented in one of two ways. First, you can select a specific O-ring material to view its compatible chemicals. Or second, you can select a specific chemical to view all its compatible O-ring materials. Chemical compatibilities are rated and displayed according to
These rubber sea water resistant are applicable in hotels, building material shops, manufacturing plants, machinery repair shops, farms, restaurants and many more. The motor system of these products are very efficient and require less maintenance. These rubber sea water resistant come with ISO, CE, SGS, FCC certifications and are safe to use.
Welcome to our Rubber Chemical Resistance Chart Here is the rubber compatibility chart that rates all popular rubber materials that comes into contact with various chemicals. Use this rubber chemical resistance chart to make sure that the elastomer or O-ring seal you choose will be compatible with the particular environment.
RubberPVC Materials. Rubber is the most cost-effective material to use where temperatures and pressures are low and the chemical environment is mild. Different elastomers offer different mechanical and chemical properties. Cloth inserted materials are better able to handle movement and high compression loads. Sponge
