Platinum cure silicone materials can be an excellent material choice for your application. You may be familiar with peroxide cure silicones, the conventional method to cure silicone, which contains a catalyst bi-product that has a smell and contains industrial chemicals. The mechanism of a peroxide cure is a free radical cure that results in a number of different by-products.  A post-cure is necessary to drive them off.  While peroxide cure silicones are great solutions for industrial and environmental applications, health care products often require an ultra-clean material. This is where platinum cure silicone materials come in.  


Platinum Cure Silicone

Focusing on a more sterile silicone, platinum cure silicone is noted for its cleanliness and high purity. Unlike peroxide cure silicones, there are no cure by-products in the platinum cured silicones. Additionally, they show stronger physical properties and lower shrinkage values.  Platinum cure silicones are cost-effective and combine high purity with FDA, USP Class VI, and RoHS compliance. These silicones are well suited for healthcare applications and medical devices.


Key Material Characteristics of platinum cured silicones:

  • Can be made custom thickness from .005 inches to .250 inches
  • Can be made on a roll in low quantity down to 25 l/f for smaller runs
  • Can be made in a MOQ of 1 molded sheet for prototypes
  • USP Class 6
  • FDA Compliant
  • Ultra-clean
  • RoHS compliant
  • Colors available: red, black, gray, and white

Common Applications:

  • Medical device gaskets
  • Membrane applications
  • High purity applications
