Discover our extensive range of silicones for candle making, specially selected for creating high-quality molds for candles, wax, paraffin, and related products. Our silicones offer excellent heat resistance, flexibility, and longevity for perfect results.
Why Silicone for Candle Molds?
Silicone is the ideal material for candle molds due to:
- Heat Resistance - Withstands molten wax up to 200°C
- Flexibility - Easy demolding for complex designs
- Non-stick surface - Candles release effortlessly without a release agent
- Detail Reproduction - Reproduces the finest details and textures
- Durability - Hundreds of candles possible per mold
- No Shrinkage - Dimensionally stable for consistent results
Recommended Silicones for Candle Making
RTV Silicones (Room Temperature Vulcanizing)
Platinum-catalyzed RTV silicones are the best choice for candle molds:
- Shore A 10-20 - Soft, flexible silicones for complex shapes and undercuts
- Shore A 25-30 - Versatile hardness for most candle designs
- Shore A 40-50 - Firmer molds for large candles and production
Polytek Silicones for Candles
- Polytek TinSil series - Tin-catalyzed, economical for large molds
- Polytek PlatSil series - Platinum-catalyzed for superior quality
- Polytek PolyGel - Gel silicones for brush-on molds
Wacker and CHT Silicones

- CHT Silicones - Reliable performance for artisan work
How to Make a Silicone Candle Mold
Method 1: Block Mold
The most commonly used method for candle molds:
- Preparation - Place your master model in a leak-proof container or build a mold box
- Attachment - Glue the model to the bottom with hot glue or clay
- Distance - Ensure at least 10-15mm of silicone around the model
- Mixing - Mix silicone components A and B according to the ratio (usually 1:1 or 10:1)
- Degassing - Remove air bubbles with a vacuum chamber (optional but recommended)
- Pouring - Pour slowly from one point, allowing the silicone to flow naturally
- Curing - Allow to cure for 16-24 hours at room temperature
- Demolding - Remove the mold and cut a pour opening if necessary
Method 2: Brush-On Mold
Ideal for large or complex objects:
- Preparation - Clean and dry the master model
- Release agent - Apply a release agent if necessary
- First coat - Brush a thin layer of silicone over the model
- Reinforcement - Add fiberglass or cotton cloth for strength
- Building up - Apply 3-5 layers until 5-10mm thick
- Mother mold - Create a support mold from plaster or plastic
Method 3: Two-Piece Mold
For complex candles without undercuts:
- Parting line - Determine where the mold should split
- First half - Cover half of the model with clay
- Registration keys - Create indentations in the clay for alignment
- First pour - Pour the first half of the mold
- Release - Apply release agent to cured silicone
- Second pour - Remove clay and pour the second half
Tips for Perfect Candle Molds
- Wick hole - Add a channel for the candle wick
- Pour opening - Make it large enough for easy pouring
- Venting - Add small channels to allow air to escape
- Wall thickness - Minimum 10mm for stability
- Support shell - Use a mother mold for large flexible molds
- Temperature - Work at 20-25°C for optimal results
Applications
- Decorative candles and sculptures
- Pillar and dinner candles
- Scented candle production
- Soy and beeswax candles
- Paraffin and gel candles
- Wax melts and tealights
- Soap and bath products (with suitable silicones)
Frequently Asked Questions
Do I need a release agent? For most platinum silicones, no, but for tin silicones, it can be helpful.
How many candles can I make? A good silicone mold lasts for 200-500+ candles, depending on use and maintenance.
Which hardness is best? Shore A 25-30 is ideal for most applications, softer for complex shapes.
