Candle making is a unique and satisfying craft that allows you to create custom candles in your own home. One of the most important factors in determining the success of your candle-making project is choosing the right mould. Silicone moulds are a popular choice among candle makers due to their versatility, flexibility, and durability. However, not all silicone moulds are created equal, and choosing between platinum-cure silicone and tin-cure silicone can be difficult. Understanding the difference between these two types of moulds can help you make an informed decision when it comes to choosing the right mould for your candle business.


Platinum-Cure Silicone Moulds

Platinum-cure silicone moulds are known for their superior quality and long lifespan. This type of silicone is made using a platinum-based catalyst, which provides a high-quality cure, resulting in a much stronger and more durable mould than moulds made from tin-cure silicone. Platinum-cure silicone is also renowned for its resistance to heat, making it ideal for high-temperature applications, such as candle making. Additionally, platinum-cure silicone moulds are highly resistant to tearing and deformation, making them the perfect choice for those who want to make high-quality candles for many years to come.


  • Durable and flexible
  • Heat-resistant
  • Tear-resistant


  • More expensive than tin-cure silicone
  • Requires a longer cure time

Lifespan: Platinum-cure silicone has a longer lifespan than tin-cure silicone, and can last for several years or even decades with proper care and maintenance, making it a cost-effective option in the long run.


Tin-Cure Silicone Moulds

Tin-cure silicone moulds are a popular choice among candle makers due to their affordability and ease of use. However, they don't have the heat resistance and durability of platinum-cure silicone, causing them to deteriorate faster. Tin-cure silicone is made with a tin-based catalyst that allows for a faster curing process compared to platinum-cure silicone, but also has a much shorter lifespan. Despite these limitations, tin-cure silicone moulds remain a popular choice for new candle makers or those seeking to create basic designs and shapes. They are also convenient to use as candles can be easily removed from the moulds.


  • Affordable
  • Faster cure time than platinum-cure silicone


  • Not as heat-resistant as platinum-cure silicone
  • Not as durable or strong as platinum-cure silicone
  • Breaks down within 12 months, depending on usage

Lifespan: Tin-cure silicone has a shorter lifespan than platinum-cure silicone, and can last for several months to a couple years with proper care and maintenance. It may require frequent replacements, making it a less cost-effective option in the long run.

Silicone Mould Making

In conclusion, both platinum-cure silicone and tin-cure silicone have their advantages and disadvantages, and the choice between them will depend on your requirements and specific needs as a candle maker. Platinum-cure silicone is more expensive but is more heat-resistant and long-lasting, making it ideal for high-temperature applications and long-term usage. Tin-cure silicone is more affordable but has a shorter lifespan and is not as heat-resistant, resulting in the need for more frequent replacements. Ultimately, the choice between these two types of silicone moulds will depend on the budget available and the desired outcome of your candles.
