HONG YE SILICONE Molding Silicone Rubber is a premium two-component RTV 2 Silicone Rubber , core Mold Making Silicone available in 10-40 Shore A adjustable hardness. As professional liquid silicone , it includes Addition Curing Silicone (Platinum cured mold silicone) and Condensation Curing Silicone Mold Rubber formulations. Featuring excellent fluidity, room-temperature curing (2-6 hours), and resistance to high temperature, acid, alkali and deformation, it supports pouring and brushing molding. Widely used in building decoration, crafts, furniture, food mold and life casting, it ensures easy demolding and high reuse rate, helping global B2B buyers reduce costs and improve production efficiency.
Product Overview
This Industrial mold silicone rubber is a versatile two-component room-temperature vulcanization liquid silicone, tailored for diverse molding needs. It offers two optimized formulations: platinum cured Mold Silicone (eco-friendly, high transparency) and condensation curing silicone mold rubber (cost-effective, wide adaptability). With outstanding operability and flexibility, it solves core pain points like mold deformation, difficult demolding and poor material compatibility in multi-industry production. Suitable for both manual mold design and industrial mass production, it’s a reliable choice for manufacturers in decoration, crafts, furniture, casting and food industries.

Product Features & Advantages
Adjustable hardness (10-40 Shore A) fits different product sizes and detail requirements. Dual formulations meet diverse budget and application needs (platinum for high-end, condensation for general use). Excellent fluidity ensures full coverage of intricate patterns, with good operability for both beginners and professionals. High resistance to high temperature, acid, alkali and deformation extends mold service life. Easy demolding avoids product damage, reducing defect rates. High reuse rate lowers long-term procurement costs. Compared to ordinary silicone, it has better compatibility with multiple materials (gypsum, resin, metal, food), with Food grade mold silicone variant meeting FDA standards.
How to Use
Step 1: Select appropriate hardness: For 20-80cm products (intricate details: 20-25 Shore A; simple designs: 25-30 Shore A); 80-150cm (intricate:25 Shore A; simple:30-35 Shore A); over 150cm (intricate:25-28 Shore A; simple:35-40 Shore A).
Step 2: Mix base silicone and curing agent evenly (more curing agent for faster drying/demolding, less for slower).
Step 3: Perform vacuum defoaming (optional, for bubble-free molds).
Step 4: Apply via pouring (large/simple patterns) or brushing (small/intricate details).
Step 5: Cure at room temperature for 2-6 hours, then demold gently.
Step 6: For ultra-soft molds or complex details, add 5-10% silicone oil (not recommended normally).
Application Scenarios
Widely used for building decorations (plaster, concrete, GRC/GFRC, art stone); crafts (PVC, plastic, wax, candle, soap); furniture (polyurethane wood imitation, resin); casting (aluminum, lost wax, bronze, tire, foundry); food molds (chocolate, cake, ice cream, baking decorations, food grade mold silicone); life casting (human body parts for prosthesis/organ dummies, Life Casting Silicone ). It helps buyers improve molding precision, shorten production cycles and reduce mold replacement costs.
Certifications and Compliance
The product holds ISO 9001 quality management system certification and CE industrial safety certification. The food grade mold silicone variant complies with FDA standards, and platinum cured mold silicone meets international environmental norms. All products meet import requirements of global markets, ensuring smooth B2B procurement and customs clearance.
Customization Options
We offer OEM customization services, including adjustable hardness (10-40 Shore A), viscosity (for pouring/brushing), curing speed (via catalyst type), and formula optimization (High transparency mold silicone, food grade, life casting grade). Packaging specifications can be customized, adapting to Rapid prototyping silicone testing and large-scale industrial production.
Production Process
Manufactured with high-purity Silicone raw materials , the product undergoes precise formula blending, closed vacuum mixing, multi-index performance testing (hardness, tensile strength, curing speed), standardized filling and batch inspection. Each link is strictly controlled by professional quality teams, ensuring stable performance and consistent quality for bulk orders.
FAQ
1. How to choose the right hardness?
Select based on product size and detail: softer silicone (10-25 Shore A) for small/intricate products, harder (25-40 Shore A) for large/simple ones.
2. Can I adjust curing speed?
Yes, increase curing agent dosage for faster drying, reduce for longer working time.
3. Is silicone oil addition allowed?
Not recommended normally; 5-10% is acceptable for ultra-soft molds or complex details.
4. What’s the storage condition?
12 months at 25℃ in sealed, dry and cool places, avoid direct sunlight.
5. Is it suitable for food or life casting?
Yes, we provide food grade mold silicone (FDA-certified) and life casting silicone for such scenarios.
