Frequently Asked Questions

What is the difference between tin-cured and platinum-cured silicone?

Tin-cured (condensation) silicone is cost-effective and suitable for general mold making. Platinum-cured (addition) silicone offers higher thermal stability, no by-products, and is ideal for food-grade and medical applications.

Is your food-grade silicone FDA approved?

Yes, our food-grade mold making silicone is platinum-cured and complies with FDA standards for indirect food contact, making it safe for cake, chocolate, and candy molds.

Can I use your silicone for life casting?

Absolutely. Our life casting silicone rubber is specially formulated to be skin-safe, ultra-soft, and highly detailed, perfect for prosthetics, special effects, and body art.

Do you offer custom formulations?

Yes, we have an in-house R&D team that can develop custom silicone formulations based on your specific viscosity, cure time, hardness, and application requirements.

What is the shelf life of your silicone products?

Unopened tin-cured silicone lasts 6–12 months, while platinum-cured silicone can last up to 12–18 months when stored in a cool, dry place away from direct sunlight.
