HONG YE SILICONE RTV Silicone for Urethane Furniture Molds is a premium two-component RTV 2 Silicone Rubber, available in Addition Curing Silicone (platinum-based) and Condensation Curing Silicone Mold Rubber variants. As core Mold Making Silicone , it features translucency, excellent heat resistance, high thermal conductivity, and outstanding resistance to urethane/resins. With nil shrinkage, high tear strength, and great fluidity, it ensures precise detail replication and multiple molding cycles. Ideal for urethane furniture molds, prototyping, and architectural restoration, it enhances production efficiency, reduces mold replacement costs, and meets global B2B buyers’ strict quality demands for furniture and craft manufacturing.
Product Overview
This professional Industrial mold silicone rubber is engineered exclusively for urethane furniture mold making, offering only RTV2 (two-component liquid silicone ) formulations. It includes two tailored options: addition curing silicone (Platinum cured mold silicone, eco-friendly and stable) and condensation curing silicone mold rubber (cost-effective for general use). Crafted with high-purity Silicone raw materials, it boasts high strength, heat resistance, and durability for repeated molding, solving core pain points like shrinkage, resin corrosion, and poor detail replication in furniture production. As a reliable Rapid prototyping silicone and mold making silicone, it fits diverse manufacturing needs from furniture to crafts.

Product Features & Advantages
Translucent design allows real-time observation of molding progress and bubble detection. Excellent heat resistance and high thermal conductivity ensure stable performance in high-temperature curing processes. Outstanding resistance to urethane, concrete, and common resins avoids mold corrosion and extends service life. Nil shrinkage guarantees dimensional stability and precise replication of furniture’s intricate textures. High tear strength and enhanced durability support hundreds of molding cycles, reducing procurement costs. Great fluidity simplifies pouring and brushing, improving production efficiency. Compared to ordinary silicone, it offers better compatibility with urethane materials, ideal for furniture mold customization.
How to Use
Step 1: Clean and dry the furniture master model thoroughly to avoid impurities affecting mold quality.
Step 2: Select addition/condensation silicone, mix Part A (liquid silicone) and Part B (curing agent) in the specified ratio (platinum 1:1, condensation 100:3).
Step 3: Stir the mixture evenly, ensuring no lumps or uneven curing.
Step 4: Perform vacuum defoaming for 2-3 minutes to remove trapped air (critical for smooth mold surfaces).
Step 5: Pour the bubble-free mixture into the mold frame, ensuring full coverage of the master model’s details.
Step 6: Allow room-temperature vulcanization (curing time varies by formula, typically 2-4 hours).
Step 7: Demold gently after full curing; the mold is ready for urethane furniture casting.
Application Scenarios
Primarily used for urethane furniture mold making (chairs, tables, cabinets, decorative furniture parts). It also applies to rapid prototyping, architectural restoration, sculpting/wax casting, concrete/GRC casting, gypsum/plaster decoration, resin crafts molding, tire molding, low melting alloys, ceramics, candles, and general plastic casting. It helps buyers improve furniture product consistency, shorten production cycles, reduce mold failure rates, and lower long-term manufacturing costs.
Certifications and Compliance
The product holds ISO 9001 quality management system certification and CE certification. The platinum-based addition curing silicone meets FDA standards (Food grade mold silicone, if applicable). It complies with international industrial silicone norms, ensuring smooth global procurement and customs clearance for B2B buyers.
Customization Options
We offer OEM customization services, including adjustable hardness (10-30 Shore A), viscosity, curing speed, and color (translucent or customized). We also optimize formulas for enhanced urethane resistance or higher heat resistance, catering to small-batch Prototype silicone testing and large-scale furniture mold production needs.
Production Process
Manufactured with high-purity silicone raw materials, the product undergoes precise formula blending, closed vacuum mixing, multi-index performance testing (heat resistance, tear strength, shrinkage), and standardized filling. Each batch is strictly inspected before shipment, supported by mature production lines and professional QC teams, ensuring stable quality for bulk orders.
