General
-
The
term elastomer is often used interchangeably with the term rubber, and is
preferred when referring to
vulcanisates.
-
Elastomer
comes from two terms, elastic (describing the ability of a material to
return to its original shape when a load is removed) and mer (from polymer,
in which poly means many and mer means parts).
-
Elastomers
are long polymer chains above their glass transition temperature. Elastomers
are usually lightly crosslinked and are easily deformed.
- Common elastomers
include polybutadiene (used in shoe soles), polyisobutylene (used in
automobile tires), and polyisoprene (natural rubber).
Processing
-
Processing
of elastomers includes extrusion, molding, Flash Removal,
Curing.
-
Polyurethanes can be molded, either by blending and pouring manually the
liquid reactive raw material in a mold or by using fully integrated casting
equipment.
-
TPE-S
compound from VTC Franceschetti Elastomeri can be easily processed using the
conventional machines and tools for thermoplastics. The final properties of
product are determined by the choice of the material grade, the processing
conditions (temperature, pressure/speed and so on), and
tool-geometry/surface-finish.
Technology
-
Nanolok
Technology is used For High Barrier Applications. Nanolok™ coatings start as
aqueous suspensions of nanodispersed silicates in a polymer matrix. They are
environmentally friendly, and can be applied via standard coating processes
to rubber substrate.
-
Nanolok™
technology provides the highest gas barrier of any polymeric coating
available on the market today.
Applications
-
Tires are
a classic example of a product made from carefully optimized compounds
consisting of several synthetic and natural rubber compounds along with
numerous reactive agents and carbon and silica particles.
-
Elastomers
like plasticized PVC are used widely in toys and consumer items.
-
Polyamide
based elastomers provide some of the most extraordinary strength and
toughness properties known and are used in top of the line sports gear and
clothing.
-
Silicone
based elastomers and fluoropolymer elastomers are used in high temperature
applications.
