HONG YE SILICONE Silicone for Soap Molds is a tailored RTV 2 Silicone Rubber designed for high-efficiency soap mold production, available in Condensation Curing Silicone Mold Rubber (industrial-grade) and Addition Curing Silicone (platinum-cured, food grade). As professional Mold Making Silicone and liquid silicone , it boasts ultra-low viscosity, excellent fluidity, and minimal shrinkage, ensuring perfect replication of soap details. Non-oily, bubble-free, and easy to demold, it features wide temperature resistance (-65℃ to 350℃) and strong durability, helping global B2B buyers cut production costs, improve batch consistency, and meet safety standards for skin-contact products.
Product Overview
Specially developed for soap mold crafting, this Molding Silicone Rubber focuses on solving core pain points of soap manufacturers—detail replication, easy demolding, and cost control. It is a two-component flowable liquid (Part A: base silicone, Part B: curing agent), offering two curing options to match diverse procurement needs. Industrial-grade tin-cure silicone delivers cost-effectiveness for large-scale soap production, while platinum-cured Food grade mold silicone ensures non-toxic, odorless safety, ideal for premium handmade soaps. Its bubble-free formula and flexible texture guarantee smooth soap surfaces and damage-free demolding, making it a reliable choice for both large factories and small craft workshops.

Product Features & Advantages
Ultra-low viscosity ensures smooth pouring, fully filling even the most intricate mold details for decorative soaps. Bubble-free formula eliminates surface defects, reducing post-processing and defective rates. Dual curing options: Industrial-grade (cost-effective, suitable for mass production); Platinum cured mold silicone (FDA-certified food grade, non-toxic, longer shelf life). Flexible 18-22 Shore A hardness enables easy demolding, no soap breakage or pattern loss. Low shrinkage ensures consistent soap size across batches, improving production efficiency. Wide temperature resistance adapts to various soap making processes (e.g., hot-pour soap). Aging and acid-alkali resistance extend mold lifespan, lowering replacement costs. Non-oily surface ensures clean soap production, no residue left.
How to Use the Product
Step 1: Prepare the soap prototype and molding frame, fix the prototype tightly; skip release agent for porous prototypes (resin, plaster), apply only for glass/ceramic.
Step 2: Choose industrial or platinum-cured silicone, weigh according to the recommended ratio, and stir thoroughly for 2-3 minutes.
Step 3: Conduct vacuum defoaming for 1-2 minutes to remove air bubbles (key for smooth mold surfaces).
Step 4: Pour the mixed silicone into the frame, ensuring all detail areas are fully covered.
Step 5: Cure at 25℃ for 3-6 hours, demold gently, and start soap pouring immediately.
Application Scenarios
Mainly used for mold making of handmade soap, scented soap, shaped soap, decorative soap, and organic soap. Also applicable to candle molds, small resin crafts, jewelry prototypes, and plaster ornaments. Suitable for soap factories, handmade craft studios, cosmetic gift suppliers, and DIY soap brands. It helps buyers enhance product competitiveness with high-detail soap designs, reduce production waste by 20%+, save labor costs via easy operation, and expand product lines with versatile molding capabilities.
Certifications and Compliance
The product meets ISO 9001 quality management system and CE industrial standards. Platinum-cured silicone is FDA and EU certified as food grade Mold Silicone , non-toxic, odorless, and safe for direct contact with skin and soap ingredients. All formulas comply with international chemical transportation and import regulations, facilitating smooth cross-border B2B bulk procurement and market entry.
Customization Options
Supports viscosity adjustment to adapt to different soap pattern complexities (from simple shapes to ultra-fine details). Offers hardness customization (15-25 Shore A) and curing speed adjustment (2-8hrs) to match production rhythms. Provides color customization for easy mold identification in mass production. Customizes packaging specifications (small test jars to industrial drums) based on buyer order volume and usage needs.
Production Process
Adopts high-purity Silicone raw materials and high-quality curing agents, undergoing precise proportioning, closed-loop vacuum mixing (to maintain fluidity and avoid bubbles), multi-dimensional testing (viscosity, shrinkage, safety, durability), automatic filling, and sealed packaging. Each batch undergoes strict quality inspection to ensure consistent performance. Mature production lines and sufficient inventory guarantee on-time delivery for both small-batch trials and large-scale bulk orders.
FAQ
Q1: Can I use industrial-grade silicone for handmade soap?
A1: Yes, it’s suitable for regular soap production; choose platinum-cured food grade mold silicone for premium or skin-sensitive soap lines.
Q2: How to avoid bubbles in the mold?
A2: Stir gently when mixing and conduct vacuum defoaming for 1-2 minutes—our formula also reduces bubble formation.
Q3: What’s the shelf life after opening?
A3: Use within 1 month after opening, stored in sealed containers at ≤25℃.
Q4: Can it be used for hot-pour soap?
A4: Yes, its 350℃ high-temperature resistance adapts to hot-pour soap processes.
Q5: Is customization available for large soap molds?
A5: Yes, we can adjust viscosity and formula to large-size soap molds while maintaining detail replication ability.
