Comparing Silicone and Plastic Molds
Flexibility and Material Properties
Silicone molds are easy to twist and flex, making it simple to release candies without breaking them. On the other hand, plastic molds maintain their rigid structure, which helps preserve sharp details - especially important for items like lollipops and hard candies. These differences in flexibility also affect how each material handles temperature, which we’ll dive into next.
Temperature Tolerance
Silicone molds can handle extreme temperatures, from freezing cold to high heat, without losing their shape or quality. Food-grade polycarbonate plastic molds (typically white) can also withstand high temperatures, exceeding 300°F (149°C). However, clear plastic molds are less tolerant of heat and are better suited for medium-heat tasks like making chocolates or gelatin-based candies. These temperature limits tie directly to the durability and cost of each material.
Durability and Cost
Durability plays a big role in determining overall cost. Here's a quick breakdown:
| Feature | Silicone Molds | Plastic Molds |
|---|---|---|
| Initial Cost | $15-30 per mold | $5-15 per mold |
| Lifespan | 3-5 years with proper care | 1-2 years average |
| Heat Resistance | -40°F to 446°F (-40°C to 230°C) | Varies by type (white plastic up to 320°F/160°C) |
| Maintenance | Dishwasher safe, easy cleaning | Hand wash recommended, more delicate |
| Storage Requirements | Flexible storage, stackable | Must store flat, avoid pressure |
As shown in the table, silicone molds are more durable and easier to maintain, while plastic molds offer a cheaper upfront option. For occasional use, the lower cost of plastic molds might be more appealing.
Performance with Different Candy Types
Chocolate Candies
The type of mold you use has a big influence on how your chocolate turns out. Clear plastic molds are great for achieving a shiny, polished finish because of their smooth surface. They also let you see through the sides, making it easier to spot air bubbles or flaws before the chocolate sets.
Silicone molds, on the other hand, can make things a bit trickier. Their porous texture can dull the chocolate's shine, and slower cooling might cause tempering problems. While silicone is flexible and makes it easier to remove chocolate, it truly shines when working with gelatin-based candies.
Gummy and Gelatin Candies
Silicone molds are the go-to choice for gummy and gelatin-based candies. Their flexibility makes it easy to remove delicate gummies without tearing or deforming them. Plus, silicone's non-stick surface means you usually don’t need extra greasing or preparation.
Plastic molds, while cheaper, have some drawbacks. They may require cooking spray, and removing the candies can be more challenging.
| Mold Type | Benefits for Gummies | Limitations |
|---|---|---|
| Silicone | Flexible, easy removal, naturally non-stick | Higher cost |
| Plastic | Budget-friendly, suitable for small batches | May need greasing, harder to remove gummies |
For applications that involve high heat, the rigidity of the mold material becomes a key factor.
Hard Candies
Making hard candies comes with its own set of challenges, especially due to the high temperatures involved. White polycarbonate molds are a top choice because they can handle temperatures over 350°F. Their rigid structure ensures sharp details and precise shapes during rapid cooling, making them ideal for lollipops and other intricate designs.
While silicone molds can technically handle high heat, their flexibility can work against you when dealing with hot sugar. Plastic molds, with their sturdy build, are better at maintaining sharp edges and details, which is especially important for hard candies and molded designs.
"Experts often recommend using silicone molds for gummy and gelatin candies, while white plastic or polycarbonate molds are preferred for hard candies. For chocolate, clear plastic molds can help achieve a smoother finish."

Ease of Use and Practical Considerations
When choosing a mold, it's not just about performance. Practical aspects like workflow efficiency and maintenance also play a big role.
Filling and Demolding
Let's break down how silicone and plastic molds differ when it comes to filling and removing your creations:
| Aspect | Silicone Molds | Plastic Molds |
|---|---|---|
| Filling Ease | Flexible, forgiving | Needs precise pouring |
| Air Bubble Removal | Simple squeeze method | Requires gentle tapping |
| Heat Retention | Slower cooling | Quicker setting |
| Demolding | Easy to flex and pop | Needs careful handling |
Silicone molds are user-friendly. You can squeeze them to evenly distribute candy mixtures and eliminate air bubbles. However, their insulating nature means cooling takes longer, which might affect how quickly your candies set.
Plastic molds are less forgiving. Their rigid structure requires you to tap them gently on your work surface to release air bubbles. For chocolate, proper tempering is essential to avoid issues with demolding and to ensure a glossy finish.
Cleaning and Maintenance
Silicone molds are low-maintenance. Most residue washes off easily with warm, soapy water, and you can even toss them in the dishwasher without worry.
Plastic molds, on the other hand, need a gentler touch. Hand-washing is best to avoid scratches, which can make future demolding harder and affect the appearance of your candies.
Storage
Silicone molds are flexible and can be rolled or folded, making them easy to store in tight spaces.
Plastic molds, while sturdier and better at preserving intricate details, require more storage space. Their rigid structure means they stack well, but you'll need a dedicated spot to keep them safe from damage.
Choosing the Right Mold for Your Needs
Key Factors to Keep in Mind
When picking molds, consider the type of candy you’re making. For hard candies, you'll need molds that can handle high heat - up to 350°F - so silicone is a good choice. On the other hand, chocolates often turn out better with plastic molds, as they can create that glossy, professional finish.
Think about how often you’ll use the molds. If you’re making candy regularly, silicone molds are worth the investment because they last longer. If you’re only making treats a few times a year, plastic molds are a more budget-friendly option.
