Why Liquid Silicone Rubber For Mold Making Is Necessary
From my experience, using Liquid Silicone Rubber (LSR) for mold making has been a game changer. The flexibility and durability it offers are unmatched, allowing me to create highly detailed molds that capture every fine detail of the original model. Unlike other materials, LSR doesn’t shrink or warp, so the final molds remain accurate and consistent every time I use them.
Another reason I rely on Liquid Silicone Rubber is its excellent heat resistance and chemical stability. This means my molds can withstand multiple casting sessions without degrading or losing shape, saving me time and money in the long run. Plus, its non-stick properties make demolding much easier, reducing the risk of damaging delicate casts. Overall, LSR has become necessary in my process because it ensures precision, durability, and ease—qualities that are essential for professional-quality mold making.
My Buying Guides on Liquid Silicone Rubber For Mold Making
When I first started exploring mold making, choosing the right liquid silicone rubber (LSR) was a bit overwhelming. Over time, I’ve learned what to look for and how to pick the best silicone for my projects. Here’s my guide to help you make an informed decision.
1. Understand What Liquid Silicone Rubber Is
Liquid Silicone Rubber is a versatile, flexible material used for making molds that capture fine details. It’s easy to work with, cures at room temperature or with heat, and offers great durability. Knowing this foundation helped me appreciate why it’s a top choice for mold makers.
2. Consider the Shore Hardness
Shore hardness measures how soft or firm the silicone is. For mold making, I prefer a softer silicone (around Shore 20A to 40A) because it flexes easily and releases castings without tearing. If your mold needs more durability or handles heavier materials, a firmer silicone might be better.
3. Check Cure Time and Method
Different LSR products cure at different speeds and temperatures. I look for a silicone with a reasonable pot life and cure time that fits my workflow. Some cure at room temperature overnight, while others require heat to speed up the process. Knowing your schedule helps you pick the right one.
4. Look for Good Tear Strength and Flexibility
A mold that tears easily is frustrating. I always check the tear strength rating — higher is better for durability. Flexibility is also important so the mold can bend without cracking, especially for complex shapes.
5. Evaluate Mixing Ratio and Ease of Use
Most LSRs come as two parts that you mix together. I prefer products with a simple 1:1 ratio because it’s easier to measure and mix accurately. Complex ratios can lead to curing problems if not precise.
6. Food Grade or Skin Safe? Consider Your Project Needs
If you’re making molds for food items like chocolates or soap, you’ll want a food-grade or skin-safe silicone. I always check the manufacturer’s specifications to ensure it’s non-toxic and safe for the intended use.
7. Volume and Packaging Size
Think about how much silicone you need. Buying small quantities is great for beginners or small projects, but if you’re doing larger molds, purchasing in bulk can save money. I always estimate my volume needs before purchasing.
8. Price vs. Quality
While it’s tempting to go for the cheapest option, I’ve found that investing a little more in quality silicone saves frustration and produces better results. Cheap silicones can have issues like poor curing, brittleness, or bad detail capture.
9. Read Reviews and Manufacturer Support
Before buying, I check user reviews to see real experiences with the product. Also, good technical support from the manufacturer or supplier is invaluable if you have questions during your mold making process.
10. Storage and Shelf Life
Silicone rubber has a shelf life and needs to be stored properly to maintain quality. I store mine in a cool, dry place and use it within the recommended period for best results.

By keeping these points in mind, I’ve been able to choose the right liquid silicone rubber for each of my mold making projects. Hopefully, this guide helps you navigate the options and pick the best product for your needs!
