Does the platinum-catalyzed cure process produce harmful byproducts?

No. Platinum-catalyzed addition cure proceeds through a hydrosilylation reaction that forms Si–C bonds; the only byproduct is ethanol, which volatilizes at processing temperatures and does not remain in the cured matrix. This is fundamentally different from peroxide vulcanization, where the peroxide decomposes into acidic fragments — for example, benzoyl peroxide systems generate benzoic acid derivatives — that remain in the material unless driven off by a post-cure baking step. Even with thorough post-cure, complete elimination of peroxide decomposition products is difficult to guarantee, and residual levels must be verified by extraction testing for medical and food-contact applications. The absence of acidic byproducts in platinum-cured silicone is the primary reason it does not yellow over time and is the preferred material system for medical devices, biopharmaceutical fluid handling, and food-grade applications. Ruixiang can provide extractables test data for its platinum-cured medical silicone tubing on request.
