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.
