详细说明
ELASTOSIL R 406/70 CN
HCR SILICONE RUBBER
Characteristics
ELASTOSIL® R 406/70 CN is fume grade high
consistence silicone rubber for general purpose
application.
ELASTOSIL® R 406/70 CN could be cured by both
peroxide and Platinum catalyst system. Cured
articles are noted for the good flexibility and good
transparence and elasticity properties. The
compounds are easily pigmented with pigment
pastes and have a good processing characteristic.
The various grades can be blended in any
proportion to achieve intermediate hardness.
Application
Postcured parts can be used for applications in
the pharmaceutical and food industries and
comply with the recommendations “XV. Silicone”
of the BfR and FDA § 177.2600 under observance
of any given limitations on extractable and volatile
substances.
Processing
ELASTOSIL® R 406/70 CN is designed for both
press curing and extrusion application.
For detailed information, please refer to our
brochure "Processing ELASTOSIL® R Solid
Silicone Rubber".
Storage
The “Best use before end” date of each batch is
shown on the product label.
Storage beyond the date specified on the label
does not necessarily mean that the product is no
longer usable. In this case however, the properties
required for the intended use must be checked for
quality assurance reasons.
Safety information
Comprehensive instructions are given in the
corresponding Material Safety Data Sheets. They
are available on request from WACKER
subsidiaries or may be printed via WACKER web
