Is platinum cure silicone safe?

Platinum cure silicone is widely recognised as one of the safest materials available for food storage and cooking applications. Its exceptional safety profile has made it the preferred choice for medical devices, baby products, and high-end kitchenware worldwide.

Regulatory Approvals and Certifications

Platinum cure silicone meets the strictest safety standards globally. It's approved by the Food and Drug Administration (FDA) in the United States, the European Food Safety Authority (EFSA), and similar regulatory bodies worldwide for direct food contact. These approvals are based on extensive testing that demonstrates the material's safety across a wide range of conditions and applications.

The material also meets medical-grade standards, including USP Class VI certification, which is the highest biocompatibility rating. This certification requires rigorous testing for cytotoxicity, sensitisation, and irritation, ensuring the material is safe for direct contact with the human body.

Chemical Inertness

The safety of platinum cure silicone stems from its chemical inertness. Unlike plastics that can leach harmful chemicals like BPA, phthalates, or lead into food, platinum silicone is completely stable and non-reactive. The platinum catalyst used in the curing process doesn't remain in the final product, leaving behind a pure, inert material that won't interact with food or beverages.

This chemical stability means that platinum silicone won't break down when exposed to acidic foods like tomatoes or citrus fruits, alkaline substances, or varying temperatures. Foods maintain their natural taste without any chemical interference.

Heat Safety

Platinum cure silicone remains safe across extreme temperatures, from freezing to high-heat cooking. When heated, it doesn't release toxic fumes or degrade into harmful compounds, unlike many plastics that can release volatile organic compounds (VOCs) when heated.

This heat stability makes platinum silicone safe for:

  • Microwave heating
  • Oven cooking up to 230°C (446°F)
  • Dishwasher sanitising
  • Freezer storage
  • Sous-vide cooking

Non-Porous Surface

The non-porous nature of platinum cure silicone prevents bacterial growth and makes it easy to sanitise completely. Unlike materials with microscopic pores that can harbour bacteria, platinum silicone can be thoroughly cleaned with simple washing, ensuring food safety with every use.

Absence of Harmful Additives

High-quality platinum cure silicone contains no:

  • BPA (Bisphenol A)
  • Phthalates
  • Lead
  • PVC
  • Latex
  • Fillers that could compromise safety

This purity makes it particularly suitable for families with allergies or chemical sensitivities.

Long-Term Safety

Studies have shown that platinum cure silicone maintains its safety profile throughout its lifespan. Unlike materials that can degrade and become less safe over time, platinum silicone remains chemically stable for years, ensuring consistent safety for food storage.

Comparison with Alternatives

When compared to single-use plastics, platinum cure silicone offers superior safety. Single-use plastic bags often contain plasticisers and additives that can migrate into food, particularly when exposed to heat or stored for extended periods. The safety margin with platinum silicone is significantly higher.

Scientific Evidence

Numerous peer-reviewed studies have confirmed the safety of platinum cure silicone for food applications. Research published in food science journals consistently shows no migration of harmful substances from platinum silicone into food simulants under various conditions.

Practical Safety Tips

To maintain the safety of your platinum silicone bags:

  • Purchase from reputable manufacturers who provide safety certifications
  • Avoid products that have a strong chemical odour
  • Replace bags if they become damaged or cracked
  • Clean thoroughly after each use

Environmental Safety

Beyond personal health, platinum cure silicone is environmentally safer than alternatives. Its durability reduces waste, and while it's not biodegradable, it can be recycled at specialised facilities and doesn't contribute to microplastic pollution.

The overwhelming scientific evidence and regulatory approvals confirm that platinum cure silicone is not only safe but represents the gold standard for food storage materials, providing families with peace of mind about their health and safety.
