What Is the Difference Between Peroxide and
Platinum Cured Silicone Tubing?
In the high purity process industry, silicone
tubing is one of the most extensively used
materials. Silicone Transparent Platinum Cured
Tube shines for a handful of significant reasons
as the industry moves away from purely stainless
fluid pathways and offers more and more
single-use solutions. The first and most
important consideration is safety. Plasticizers
and other additives that can leach into the
product and produce toxicological concerns are
not present in silicone tubing. Second, silicone
tubing manufactured by Silicone Transparent Tube
Manufacturer in India is extremely flexible,
resistant to kinking and ripping, and ideal for
peristaltic pumps. We need monomers to make
silicone tubing, or any polymer for that matter.
Silicone elastomer is used to make silicone
tubing. The monomers of the soon-to-be polymer
are the foundation silicone elastomers. To
combine these monomer groups into tubing that can
be extruded into useable geometries, the tubing
must be cured, or vulcanised, which crosslinks
the monomers into polymers and allows them to be
extruded. There are two major cure systems for
silicones addition cure and free radical
treatment. From here, we may purchase our two
main types of silicone tubing platinum and
peroxide cured, the differences of which will be
discussed in this piece.

Vinyl-functional polymers and a catalyst, such as
platinum, are used in addition cure systems to
jump start the process (most cure methods will
use either an organo-metallic complex or a
platinum salt). The main advantage of addition
cure systems is that the finished polymer has no
by-products that can leach. However, the cost of
platinum catalyst is more than for other curing
processes, which is reflected in the final
product price. Because Silicone Transparent
Peroxide Cured Tube use difficult-to-control free
radicals, final product consistency isn't as
good as it is with platinum cured silicones.
Peroxide cured tubing's opacity is likewise
affected by high temperature post-cure, making it
cloudier than identical platinum cured tubing.
Peroxide-cured tubing has a higher opacity than
platinum- catalyzed tubing. Silicones that have
been peroxide cured have a tackier feel than
silicones.
The extremely low amounts of extractables and
leachables in platinum cured silicone compounds
are the primary benefit. While post-cure
procedures are effective at reducing the amount
of siloxanes in peroxide-cured processes, some
organic acids remain. By- products are not an
issue because platinum cured goods may be
controlled. As a result, platinum-cured items
have a reputation for being the purest. To aid in
tube selection, all good silicone tubing
products should have complete characterization
and validation profiles, including total organic
carbon profiles and relative amounts of
extractables and leachables. To summarise, in the
area of high purity processes, there are two
basic types of silicone tubing. Both free
radical (peroxide) and addition (platinum) curing
methods provide a safe, long-lasting, and
efficient means of transporting and manipulating
fluids. However, the two cure techniques yield
materials with distinct properties, which should
be addressed before choosing tubing.

While peroxide cured silicones are less
transparent, they have less spallation and have a
longer pump life. Platinum-cured goods have
exceptionally low extractables and leachables,
resulting in ultra-high purity.
