Silicone for Soap Molds with Condensation Curing

HONG YE SILICONE’s Soap Mold Silicone is a high-performance RTV 2 Silicone Rubber designed for soap molding, available in condensation curing and platinum cured (food grade) options. Featuring ultra-low viscosity, excellent fluidity, and shrinkage ≤0.2% (0.1% for platinum type), it replicates fine details perfectly. Non-toxic, odorless, and FDA-certified, this Mold Making Silicone ensures easy demolding, durability for repeated use, and resistance to -65℃~350℃. Ideal for batch production of handmade or custom soaps, it meets industrial and food contact safety standards, delivering cost-saving value for manufacturers.

 

Our Soap Mold Silicone is tailored for the soap-making industry, combining practicality and reliability. While standard industrial-grade Condensation Curing Silicone Mold Rubber (tin cure) meets basic molding needs with a 100:3 silicone-to-catalyst mix ratio, the Platinum cured mold silicone (addition cure) offers superior performance—longer shelf life, non-toxicity, and FDA certification—making it ideal for food-contact soap products. With low viscosity and high fluidity, it penetrates every detail of prototypes, ensuring soap molds capture intricate patterns and textures, suitable for both small-batch handmade soaps and large-scale industrial production.

Crafted with advanced formulas, this Molding Silicone Rubber stands out with key advantages: Ultra-low viscosity ensures seamless flow to replicate the finest soap mold details—from embossed patterns to textured surfaces. Its flexible yet durable structure enables easy demolding without damaging soap products, while being non-oily and bubble-resistant for smooth mold surfaces. The platinum cured variant, as a Food grade mold silicone, is non-toxic and odorless, complying with global food safety standards. With excellent aging, acid, and alkali resistance, the molds maintain performance through hundreds of uses, reducing replacement costs.

 

1. Prepare a clean, dry prototype (soap design master) and apply mold release agent if needed.

2. Mix silicone base with catalyst at 100:3 ratio (adjust for curing speed) and stir gently to avoid bubbles.

3. Degas the mixture (vacuum or natural standing) to remove air bubbles.

4. Pour the mixture slowly over the prototype, ensuring full coverage of details.

5. Allow 24hrs of room temperature curing (or use heat to accelerate).

6. Demold carefully—flex the silicone mold for easy separation, then reuse for soap casting.

 

Primarily designed for soap molding, this silicone is suitable for: Handmade soap workshops, industrial soap manufacturers, custom soap designers, and craft businesses. It works with various soap bases (glycerin, cold-process, melt-and-pour) and can also create molds for complementary products like candle soaps or small resin decorations. Compatible with materials such as gypsum and wax for prototype making, it supports versatile production needs.

 

 Value for Buyers

- Cost Efficiency: Durable molds reduce replacement frequency, lowering long-term production costs.

- Production Efficiency: High fluidity and easy demolding speed up mold making and soap casting processes.

- Quality Assurance: Precise detail replication enhances soap product aesthetics and market competitiveness.

- Safety Compliance: FDA-certified food grade option eliminates safety risks for skin-contact and decorative soaps.

- Versatility: Two curing types meet different budget and quality requirements, supporting diverse business scales.

 

Our Soap Mold Silicone adheres to international standards, holding ISO9001 quality management system certification, CE safety certification, and FDA certification for platinum-cured food grade variants. All products pass pre-production sampling and final shipment inspection to ensure consistency and compliance.

 

We offer OEM services and customization: Adjust hardness (10-30 Shore A), viscosity, curing time, and color to match specific production needs. For large-volume orders, custom packaging and formula tweaks are available to optimize your molding process.

 

From high-quality Silicone raw materials selection to formula blending, our production follows strict quality control: Raw material testing → precise ingredient mixing → degassing → sampling inspection (viscosity, shrinkage rate) → automated filling → final quality audit. Our 20 production lines ensure stable supply, with lead times within 1 month.

 

1. What’s the difference between condensation and platinum cured silicone for soap molds? Condensation type is cost-effective for industrial use, while platinum type is FDA-certified, non-toxic, and longer-lasting—ideal for food-contact soaps.

2. Can the mold be reused? Yes, the silicone mold can be reused 50-200 times (varies by type and usage), offering excellent durability.

3. How to adjust curing speed? Modify the catalyst ratio (100:2-5) or use heat (40-60℃) to accelerate curing; lower ratios slow it down.

4. Is it safe for skin-contact soaps? The platinum-cured variant is FDA-certified, non-toxic, and safe for skin-contact products.
