Platinum cure silicone, also called addition cure silicone, are two-component high tear strength and flexible mold or casting compounds. They are recommended as a mold material for casting polyurethane, epoxy, or polyester resins, wax and a wide range of other casting materials.
What is platinum silicone used for?
Applications and Benefits High purity platinum-cured silicone is often used in the production of pharmaceutical, biotechnology, injectables, and food and beverage products. Any processes that require long-term exposure to heat or tension, detailed customization, or extreme hardness.
What is the difference between silicone and platinum silicone?
Silicone rubber is sensitive to sulfur that can be found on different surfaces and are present in some types of modeling clay. Platinum-cure silicone rubbers are critically sensitive to sulfur and will not cure under any circumstances when exposed.
Is platinum cured silicone safe?
Platinum Cure Silicone: While good for making molds for casting a variety of materials, platinums also have application and physical properties that other rubbers do not. As a result, they are used for other applications. For example, some are certified “skin safe” and can be applied directly to human skin.
Why use platinum cured silicone tubing?
Platinum-cured tubing has a smoother surface, which means less protein binding. It is ideal for medical device, chemical analysis, bulk active drug and pharmaceutical production applications, particularly where there is long-term contact with the process fluid.
What is platinum silicone made from?
Silicone is made of a silica backbone, not a hydrocarbon backbone like plastic. Platinum silicone is very pure and needs no plasticizers to stabilize it or make it flexible, no bisphenols, no pvc, and no phthalates.
How does platinum silicone cure?
When we talk about platinum or peroxide curing in the silicone world, curing is when the silicone rubber is chemically cross-linked by means of the addition of a peroxide or platinum curing agent. The curing agents differ chemically to give the end product, in this case silicone, different properties.
Does platinum cured silicone contain platinum?
Platinum-Cured Silicone A platinum-catalyzed system is made up of two silicone elastomer base parts, both of equal weight. One part contains the platinum catalyst and the other part contains the crosslinker.
Is platinum a silicone medical grade?
Standard and food grade silicones are cured with peroxide. On the other hand, curing with platinum is more expensive, but the resulting silicone is cleaner and purer, and does not contain any fillers or byproducts. Medical grade silicones are cured with platinum – which is what we use.
How does platinum cure silicone work?
Tin (condensation) cured silicone rubber uses tin salts as a catalyst and uses moisture in the air to transform from liquid to solid. Platinum (addition) cured silicone rubber uses a platinum catalyst and uses heat to transform from a liquid to a solid.
Is platinum cured silicone porous?
Platinum-cured silicone has a high quality, long life and is non-reactive with bodily fluids and skin. Essentially, the higher the quality of silicone, the less porous the material. The ‘platinum’ label also refers to the clean standard of the room where the product is manufactured.
What is platinum cured?
Platinum Cure Silicone Rubber. Platinum Cured Silicone. Designed to increase the productivity of the moulding operation. The rapid reaction of the platinum catalyst means that thicker section parts can be cured in a faster time at the same moulding temperatures as the usual peroxide system.
How do you cure silicone?
Silicone rubber may be cured by a platinum-catalyzed cure system, a condensation cure system, a peroxide cure system, or an oxime cure system. For the platinum-catalyzed cure system, the curing process can be accelerated by adding heat or pressure.
What is platinum silicone?
Platinum-Cure Silicone. Platinum cure silicone, also called addition cure silicone, are two-component high tear strength and flexible mold or casting compounds. They are recommended as a mold material for casting polyurethane, epoxy, or polyester resins, wax and a wide range of other casting materials.
Is silicone tubing flexible?
Previously Purchased. Silicone tubing remains flexible over a wide temperature range. It offers high tensile strength, extreme temperature resistance, smooth inner surface, and excellent pliability. Use it for medical tubing, analytical instrumentation, beverage dispensing, food and dairy processing, electronic equipment,…
