If you are searching for reliable places to buy silicone rubber moulds for your next resin, plaster, or wax project, this guide will help you choose the right option. Whether you are a professional crafter or just starting with mould making, understanding the different types of silicone rubber available and what sets them apart will ensure you achieve precise and long-lasting results for any creative or industrial use.

Silicone Rubber Moulds: Comparison and Key Features

Silicone rubber moulds are a cornerstone in crafts, prototyping, and industrial casting. The major factors to consider when choosing the right mould material include flexibility, detail reproduction, safety, curing time, and compatibility with your casting medium. You’ll find liquid silicones for complex, high-detail shapes, and silicone putties for quick, hand-moulded forms. Some options specialise in fast curing or toxin-free handling, while others excel at minimising shrinkage. Comparing features across the available range helps you pick the optimal match for your specific project or material needs.

Compare visual properties of translucent, liquid and putty-type silicone rubbers to quickly assess which is most suited for your project. Notice the key differences in clarity, flexibility and workflow between “Pure Mould”, “I–Gum”, and “Liquid Mould” silicones.

“Pure Mould” – Translucent Liquid Silicone Rubber for Mould Making

“Pure Mould” – Translucent Liquid Silicone Rubber for Mould Making stands out for those needing a platinum-based, translucent and fast-curing silicone. Ideal for detailed casts in resin, plaster, cement and even candle wax, it offers a straightforward 1:1 mixing ratio with a swift curing time of 3–8 hours. Its clear quality allows you to monitor the curing process, while its durable mechanical structure enables repeated use and reduced shrinkage—perfect for both hobbyists and professionals alike. Non-toxic, solvent-free and made in Italy, it’s great for creating long-lasting, reusable moulds without safety concerns.

“I–Gum” – Non-Toxic Silicone Putty for Mould Making

If you prefer a putty for hand-shaped or emergency moulds, “I–Gum” – Non-Toxic Silicone Putty for Mould Making is a user-friendly and forgiving choice. You simply mix equal parts by hand, with no need for gloves, thanks to its non-toxic and odourless formulation. With a working time of about 20 minutes, it’s suitable for crafting smaller pieces, coasters, or frames in resin, wax, cement or polyurethanes. Its ease of use and safety make it a popular choice for beginners and educational environments.

“Liquid Mould” – Casting Liquid Silicone Rubber for Detailed Reproduction

For the most intricate details—think jewellery, artistic reproductions, or technical models—“Liquid Mould” – Casting Liquid Silicone Rubber, 5–40 Shores, Bi-Component A+B and its larger format, “Liquid Mould” – Casting Liquid Silicone Rubber, 15 Shores 20.8 kg, are professional-grade solutions. Both utilise a bi-component system, offering flexibility to capture extremely fine details, undercuts, and complex textures. Ideal for small objects or repetitive casting, these silicones can handle resin, soap, polymer pastes, wax and more, making them suitable for everything from garden ornaments to technical casting.

Choosing the Right Silicone Mould Material: Tips and Project Types

Select the silicone rubber that aligns with your mould size, desired detail, available working time and safety preferences. For candle or jewellery makers who need to monitor fill levels, a translucent silicone like “Pure Mould” is the go-to. Those doing quick hands-on shaping may favour “I–Gum” putty. For complex artistic or technical applications, “Liquid Mould” liquid silicones offer optimal flexibility and reproduction accuracy. Remember to factor in your casting material and frequency of use—durability, shrinkage, and handling safety are just as important as initial set-up ease and cost.
