Rubber Glossary
- Abrasion resistance: The resistance to abrasive
wear.
- Acid Resistant: Resistance to the action of
acids.
- Aging: Exposing materials to an environment for
a period of time.
- Butyl: Synthetic rubber exhibiting very low
permeability to gases. Copolymer of isobutylene and isoprene.
- Durometer: An instrument for calculating the
hardness of vulcanized rubber.
- Elasticity: The property to return to its
original shape after deformation.
- Elastomer: A term used to describe elastic
polymers having rubber-like behavior.
- Elongation: Extension which is produced by a
tensile stress.
- Expanded Rubber: Cellular rubber made from a
solid rubber compound and having closed cells.
- Extrusion: The process under which pressure is
forced through the opening of a die in order to obtain a desired
cross sectional shape.
- Hardness (durometer): It is a property of
rubber stocks which is difficult to define except by considering the
methods used to determine it.
- Heat resistance: The ability of rubber to
retain its properties even under the destructive influence of heat.
- Hypalon: A synthetic rubber that is completely
resistant to ozone attack under the most extreme conditions and also
possesses excellent color stability including the action of acids,
bases, and many other chemicals.
- Low temperature flexibility: This is the
temperature at which the rubber becomes too stiff to function in its
usual manner.
- Natural Rubber: Rubber obtained from latex of
the rubber tree.
- Neoprene: A polymer of chloroprene and is
prepared from coal, salt and limestone. Neoprene is a synthetic
rubber used in weather-resistant products, adhesives, shoe soles,
sportswear, paints, and rocket fuels.
- Nitrile rubber: A copolymer of butadiene and
acrylinitrile.
- Oxidation resistance: The ability of rubber to
withstand the reaction of atmospheric oxygen.
- Oil Resistant: Ability of a vulcanized rubber
to withstand the swelling and deteriorating effects of various type
of oils.
- Plasticisers: Liquids which are used to soften
rubber.
- Polymer: It is a general term used to describe
all rubbers and plastics.
- Resilience: Capability of a material to return
to its original size and shape even after after deformation.
- Rubber: A material that displays elastic
properties that allow recovery from large deformations quickly and
forcibly.
- SBR: Styrene Butadiene Rubber. Copolymer of
Butadiene. An all-purpose type synthetic similar to natural rubber.
- Silicone rubber: A type of synthetic rubber
containing silicone.
- Synthetic rubber: Man-made rubber
- Temperature Range: It is the range in which it
shows the lowest temperature at which rubber remains flexible and
the highest temperature at which it will function.
- Tensile strength: The tensile strength of a
rubber compound is the resistance of the rubber to rupture under
tension.
- Vulcanization: An process in which a rubber
compound through a change in its chemical structure becomes less
plastic and more resistant to swelling by organic liquids and
elastic properties are conferred, improved, or extended over a wider
range of temperature.
