These are cured by heating to high temperatures. Curing silicone basically means letting it dry. Class VI. Platinum (addition) cured silicone’s can be heat accelerated, for every 10 degrees above 70°F you can reduce the cure time in half, so if you heat the platinum cured silicone at 150°F it will be ready to use in 20-30 minutes. Developed for the biopharmaceutical industry, Pumpsil is exceptionally pure tubing offering an ultra-smooth bore which helps minimise protein binding and ensure high purity in the finished product. Let’s start from the beginning. ELASTOSIL® solid silicone rubber grades are preferred. Addition Cure RTV (Dark Pink) - catalyzed using platinum so sometimes referred to a Platinum Cure. Tip: Post-curing the freshly cured silicone in the oven for 4-6 hours at 70 degrees centigrade will improve the mechanical properties of the mould and give it a longer working life. Contact with these incompatible chemicals can inhibit their cure and result in a partially cured mold/cast. Although the silicone material shrinks slightly (2 to 3 percent) during cure, Lindstrom says the bag’s design takes that into account, resulting in a “perfect” fit. The platinum catalyst used in addition cure silicones is susceptible to some chemicals like nitrogen, sulphur, phosphorus, sulphur vulcanized rubbers and condensation cure silicone rubbers. Validations and extractables: Silicone: Platinum-cured silicone is inherently purer than perocide-cured silicone and offers fewer extractables (substances that can be drawn out of a material). 2017 A Liquid Silicone Rubber material is a two-part platinum-cured mechanical properties compared to metal particle filled silicones and can TAP Platinum Silicone is a low viscosity, two-part, platinum cure silicone which vulcanizes at room temperature (RTV).

Even at extreme temperatures, the thermal conductivity, tensile strength, dielectric strength, and tear strength remain superior to other organic rubbers. These include: Pharmaceutical and biotechnology applications; platinum-cured silicone tubing is an excellent choice for fluid transfer. Why is silicone rubber so expensive? Silicone costs more than other synthetic rubbers because it Platinum-cure silicone lasts for more castings than tin-cure silicone, all else being equal, and platinum cure silicone resists shrinking as it cures much better than tin-cure. Platinum • Peroxide-cured silicone is typical for industrial uses • Platinum-cured is cleaner and better for use in high-purity applications (medical, pharmaceutical) • Platinum-cured has lower extractables and odor • Platinum-cured typically costs more although Saint-Gobain has platinum silicones At Jehbco, platinum and peroxide products are never post-cured in the same unit, to avoid the peroxide leachables damaging the platinum cured silicone3. Platinum cured silicone body, reinforced walls, amazing storage capabilities, and a durability that rips - honestly, what’s not to love about our Eyce Spoon?.

These cover a broad range of products and processes to suit specific market and application requirements. Specialty Silicone Products (SSP) uses platinum-cured silicones to produce septa that are ultra-clean for analytical purity. In a traditional peroxide cure silicone rubber, thermal breakdown of the peroxide creates the chemical that forms the cross links between the polymer chain. Unlike the acetoxy system, methyl ethyl ketoxime is released with the oxime curing systems, and an alcohol is released with the alkoxy curing systems, and as such they are non-corrosive. AdvantaPure’s APST has undergone testing involving USP, ISO, CFR, EP, 3-A and NSF standards. This platinum can be neutralized by sulfur, amine and tin salts, leaving a potting compound with areas of cured material where the contamination is located. The peroxide or free radical system is the oldest cross-linking chemistry for silicone rubber, but it may release unwanted byproducts, such as volatile organic acids (VOAs), without post-curing. Platinum-Cured Silicone: Pros and Cons. I would not imagine there being more steam trapping than resin molds, since both resin and silicone are not permeable. Peroxide-cured (highest temp/strongest) tubing is cheaper than Platinum-cured (most sterile, purest silicone, but weaker) and gets the job done. A good deal of HCR silicone is peroxide cured and used for extrusion, transfer, or compression molding. The type of silicone used, tin or platinum cured, is an important factor when looking at this problem.
