Platinum Cure Silicone Rubber

Platinum Cure Silicone Rubber Uses

Also known as addition-cure silicone, platinum cure silicone rubber exhibits the lowest long-term shrinkage and has the longest library life of all mold rubbers (with a price tag to match). While good for making molds for casting a variety of materials, this rubber also has applications and physical properties that other rubbers do not. As a result, they have multiple uses. For example, some are certified “skin safe” and can be applied directly to human skin. The body safe silicone rubbers act great as molding, since they can safely be placed on the skin.

They are also used for making prosthetic and orthotic devices, skin safe fx appliances and effects, etc. Some are certified “food safe” for culinary applications, as well. There are many applications for these sorts of rubbers. The possibilities are endless. Creative minds can take platinum cure silicone rubber and create practical items that are great for day-to-day uses.

Other common uses include any processes in which the ability to withstand temperature extremes, radiation, corona, ozone exposure, moisture, and/or steam is needed. High purity platinum-cured silicone is often used in the production of pharmaceutical, biotechnology, injectables, and food and beverage products. It is also used for any processes that require long-term exposure to heat or tension, detailed customization, or extreme hardness.

6 Common Features of Platinum Cure Silicone Rubber

Here are 6 common features when using platinum cure silicone rubber.

1. Long Shelf Life & Working Time: It offers consistent performance over time with longer pot life and cure control compared to tin-cure silicone. No byproducts, which is unlike tin-cure silicone. Platinum cure silicone rubber does not release alcohols or other substances during curing.
2. High Heat Resistance: It is able to withstand 200–250°C (392–482°F) or higher depending on the formulation. It is often used for high-temperature applications, such as casting molten materials.
3. Chemical Resistance: This material offers great resistance to different chemicals, including UV light, ozone, and weathering. This makes it ideal for outdoor or long-term applications.
4. Excellent Mechanical Properties: Platinum cure silicone rubber offers high tear strength and elasticity. It is durable and flexible, even for intricate molds, while also offering low shrinkage.
5. Translucency & Customization: It is usually translucent or clear, which means it can be pigmented easily. This makes it a good option for color matching and visual inspection applications. Customization is simple and easy with platinum cure silicone rubber.
6. High Purity & Safety: This material is non-toxic & skin-safe, which is ideal for medical, prosthetic, and food-contact applications. FDA compliant grades available, too, making it suitable for molds used in baking, candy making, etc.

Platinum Cured Silicone Rubber Advantages

• Platinum curing process produces no peroxide residues. What this means is the risk of mold fouling is greatly decreased. This reduces down time, which improves overall productivity.
• Improved product clarity and consistency as well as potentially better elongation, tensile strength, and tear strength compared to peroxide-cured materials.
