Polymer Range
Australian Technical Rubber (ATR) will recommend a polymer to suit your specific application.
Natural Rubber
Natural Rubber is still one of the best polymers available to date. It has great physical properties when used in dynamic engineering applications such as anti-vibration mounts, bump stops and torque arm bushings. Natural rubber has excellent tensile strength, elongation and compression set values.
Chloroprene (Neoprene)
Commonly known as Neoprene is one of the first synthetic rubbers and has outstanding dynamic properties. Chloroprene offers good chemical resistance, great ozone resistance and withstands all weather/thermal conditions (- 40 up to 100 degrees Celsius). Due to its wide range of good properties it is commonly used and blended with other rubbers for many industrial applications.
Styrene-Butadiene Rubber (SBR)
SBR is an immensely popular synthetic rubber on the market due to its multi-purpose and low cost. It is an abrasion-resistant, anti-cracking synthetic rubber, commonly used in tyres. SBR is a good general-purpose rubber.
Ethylene Propylene Diene Monomer (EPDM)
EPDM is a versatile synthetic rubber which compared to natural rubber can withstand more extreme conditions and has better durability. EPDM rubbers are the most resistant to sunlight and ozone. They can withstand a wide range of temperatures.
Fluro-Elastomer (Viton)
A vital polymer, also known as FKM. Has one of the highest heat resistants with minimal swell and withstands violent chemical changes due to its strong bonds, high fluorine to hydrogen ratio and single carbon backbone. Fluro elastomers have great compression set values, chemical resistance and temperature resistance, but have poor elongation and dynamic properties. There for it is commonly used in seals such as O-rings or Toric seals.
Silicone
Most commonly used in the food industry due to its high-quality physical properties including flexibility, excellent compression set, resistance to chemicals, environmental influences (including extreme heat/cold), flame resistance and water-repellent surface.
ATR only uses the highest quality of WACKER silicones for compression moulding which are also FDA approved. Refer to their website for further details.
Nitriles: Nitrile Butadiene Rubber (NBR)
Nitriles are a synthetic rubber made from acrylonitrile and butadiene. Also known as Nitra or Buna-N; it is the most commonly used elastomer in the seal industry. Highly resistant to fuel, oil, water, silicone greases and hydraulic fluids. Much cheaper than fluoro elastomers, tear resistant and has good rebound/tensile strength.
Hydrogenated Nitrile Rubber (HNBR)
Has superior chemical structure compared to NBR, with improved abrasion, resistance to oils, solvents and temperature.
Carboxylated Nitrile Butadiene Rubber (XNBR)
Has an addition of carboxyl group, which further improves its durability, resistance to solvents and oils, and thermal stability of the rubber. Commonly used in dynamic assembly of rod wipers and seals.
ATR has extensive experience when moulding Nitriles, whether it be a standard NBR through to the highest of quality XNBR, we will have a solution for your problem.
Polyurethane (PU)
Polyurethane is a unique polymer, where its elastic ability means it can be repetitively stretched and changed like a plastic. It has low-cost tooling options. Materials are hard-wearing, flexible, can be coloured and finished off with gloss to desired level.
