| Butyl rubber is a copolymer or isobutylene and a small percentage of isoprene and has a very low permeability to air and other gases. It has excellent resistance to ozone, oxidation and sunlight, with an excellent temperature range of -45° C to + 130° C. Butyl has a very low resilience which makes it ideal for vibration damping and shock absorption applications but offer a moderate resistance to abrasion and compression set. With careful compounding, Butyl compound can be made to acquire really good tensile strength. It is resistant to most inorganic products and highly resistant to mineral acids, alkalines and aqueous acids. We do not recommend its use in applications where resistance to oils and Hydrocarbons is required. |

CR or Chloroprene is a homopolymer of chloroprene or chlorobutadiene. It has excellent mechanical and abrasion properties even without reinforcing filters and has a reasonable resilience in grades over 60° shore A. It displays good resistance to heat, ozone and weathering and also gives good adhesion to metal. The recommended operating temperature range is between 40°C to +125°C. It has good resistance to inorganic hydrocarbons. We also offer retardant grades.

| EPDM or Ethylene Propylene Diene Monomer can be vulcanized by using conventional method of using sulphur. It has an excellent operating temperature range of -45° C to + 120° C. It has highly recommended for out door uses as it extremely resistant to oxidation, U.V. Rays and Ozone. However, EPDM does not have good oil resistance or adhesion properties. It is resistant to many chemicals and solvents and shows good resistance to many corrosive chemicals. |
|
Hypalon is very resistant to attack by oxygen and ozone, and properly compounded products show excellent weathering resistance. High tensile strength is characteristic of hypalon vulcanizaes, which do not need the use of highly reinforcing fillers for good tensile properties.
Compounds can be formulated for excellent abrasion resistant and for brittle temperatures as low as -60°c (-76°F). Hypalon vulcanizaes show execellent resistant with an "EE" rating by ASTM D2000 being obtainable. They Can also be compounded for good flame resistance.

| Nitrile rubber or acrylonitrile butadiene rubber is a copolymer of butadiene and acrylonitrile. It has good general resistance to oil along with good mechanical properties especially tensile strength, flexing, compression set and impermeability to gases. It has moderate aging properties and good adhesion to metal. Its recommended operating temperature range is -30° C to + 120° C. It also displays a good resistance to inorganic chemical products except antioxidant agents and chlorine. It gives satisfactory resistance to general hydrocarbons. Due to its polar nature, we do not recommend its use with polar liquids like ketones, ethers and amines. |

Water intended for human consumption without imparting any toxic effect is drinking water. Water of sufficient quality to serve as drinking water is termed as potable water whether it is used as such or not. The non-metallic materials can cause changes in water quality when it comes in contact with it.
BS 6920 and its modified version AS/NZS 4020:2002 (for Australian and New Zealand requirements) is the method for testing the water quality –i.e, ‘Testing of products for use in contact with drinking water’ and any non-metallic product should comply with these test requirements for getting the approval given by Water Quality Centre (WQC).
Zenith PWS has been developed for using in contact with drinking water which has been met all the technical and biological property requirements as tested by following the corresponding Standards.
Zenith PWS is a high performance and low specific gravity (1.13) EPDM rubber compound which can be applied for water fitting (supplying) parts e.g., lining, joining, gaskets, membranes, cisterns, O-rings, washers that are used in contact with drinking water.

Silicone rubber is physiologically inert, thus making it the preferred choice of medical, pharmaceutical and food processing industries. Silicone have comparatively low mechanical properties, tensile strength, elongating and tear strength, however they keep constant even at high temperatures but should not be used with high pressure steam. Its resistance to oil and hydrocarbon products is fairly limited and similar to that of Chloroprene rubbers. Reasonable resistance to to a whole range of general chemical products, but acids, alkalis, esters and kerosene should be avoided. Silicone has excellent resistance to heat (dry air), at +200°C intermittent. It remain flexible at low temperatures of -70°C and it is also resistant to ultra-violet light, Ozone and weathering. Exhibits low inflammability and low smoke toxicity. It has good electrical insulation properties.
Zenith manufactures numerous types of silicone compounds for various applications.

| Fluoro Elastomer rubber or Viton is based on hexafluoropropylene vinylidene fluoride. The polymer has high resistance to heat with a temperature range of -40° C to + 250° C. It has also possesses a good flame resistance and are usually self extinguishing. FKM’s have excellent resistance to oxygen, ozone and natural weathering and also have outstanding resistance to compression, especially at elevated temperatures. Its resistance to most solvents and chemicals give long service life as it has excellent resistance against huydrocarbons, aliphatics, aromatic and chlorinated chemicals and resistance to acids and alkalis including oxidants. However, they have poor performance against ethers, ketones and bases. |

THE MATERIAL
Butyl: The polymer butyl (IIR - isobutylene isoprene - rubber) is an elastomer with a small number of double bonds, produced through co-polymerisation of isobutylene and isoprene.
EPDM: The polymer EPDM, ethylene-propylene rubber, is produced through co-polymerisation of ethylene, propylene and diene monomer, producing a polymer made up of saturated linear macromolecules with a paraffinic structure.
In addition to the base polymer, both EPDM and Butyl contain reinforcing carbon black, fillers, process chemicals, antioxidants and vulcanising agents. After mixing the ingredients into a homogenous plastic compound, two layers of the rubber are rolled out in a calender to form a double sheet. Vulcanisation is then carried out. The long rubber molecules in the material are cross-linked through heat and pressure, creating an elastic membrane.
RESISTANT TO THE ENVIRONMENT
The vulcanisation process means that the material differs from all thermoplastic products, in that its properties are not affected by varying temperatures. The product is chemically stable and always returns to its original dimensions after stretching.
The cross-linked molecular structure gives EPDM and Butyl rubber their unique properties. Ageing or changes in characteristics are negligible despite decades of exposure to the atmosphere, sunlight, UV radiation, chemical fallout, water or major temperature fluctuations.
