HONG YE SILICONE RTV liquid silicone for PU Furniture Molding is a premium two-component RTV 2 Silicone Rubber, available in Platinum cured mold silicone (platinum catalyst) and Condensation Curing Silicone Mold Rubber (tin catalyst) variants. As core Mold Making Silicone , it features excellent heat resistance, high thermal conductivity, outstanding urethane/resin resistance, and nil shrinkage. With great fluidity, high tear strength, and enhanced durability, it ensures precise detail replication and multiple molding cycles for PU furniture. Shelf life of 12 months (≤32℃), compliant with global certifications, it helps B2B buyers reduce mold replacement costs, improve production efficiency, and guarantee consistent furniture quality.
Product Overview
This professional Industrial mold silicone rubber is tailored exclusively for PU furniture molding, belonging to our liquid silicone product line. It is a room-temperature vulcanizing (RTV) two-component formula, offering two optimized options: platinum cured Mold Silicone (Addition Curing Silicone, eco-friendly, stable) and tin-catalyzed condensation curing silicone mold rubber (cost-effective for mass production). Crafted with high-purity Silicone raw materials, it solves core pain points like mold corrosion by PU resin, shrinkage deformation, and short service life, making it a reliable choice for global furniture manufacturers, architectural restoration enterprises, and craft producers.

Product Features & Advantages
Compared to ordinary silicone, our product stands out with:
1. Excellent heat resistance and high thermal conductivity, adapting to PU curing temperature requirements without mold deformation.
2. Outstanding resistance to urethane, concrete, and common casting resins, avoiding mold corrosion and extending service life.
3. Great fluidity for easy pouring and full coverage of intricate furniture textures (e.g., carvings, reliefs).
4. High tear strength and enhanced durability, supporting 200-500 molding cycles, reducing procurement costs.
5. Nil shrinkage, ensuring dimensional stability and consistent PU furniture precision.
6. Dual catalyst options (platinum/tin) to match different budget and production needs.
7. Room-temperature vulcanization, no extra heating equipment, saving energy.
How to Use
Step 1: Clean and dry the PU furniture master model thoroughly, remove impurities to avoid mold defects.
Step 2: Select platinum/tin silicone, mix Part A (liquid silicone) and Part B (curing agent) in the specified ratio.
Step 3: Stir evenly for 3-5 minutes to ensure uniform curing.
Step 4: Perform vacuum defoaming for 2-3 minutes (critical for smooth mold surfaces).
Step 5: Pour the bubble-free mixture into the mold frame, ensuring full coverage of the master model.
Step 6: Allow room-temperature curing (4-6 hours for platinum, 2-4 hours for tin). Step 7: Demold gently after full curing; the mold is ready for repeated PU furniture casting.
Application Scenarios
Primary application: PU furniture molding (chairs, tables, cabinets, decorative furniture parts). Extended applications: Architectural restoration (reliefs, historical building components), sculpting/wax casting, concrete/GRC casting, gypsum/plaster decoration, resin crafts molding, tire molding, low melting alloys, ceramics mold making, candles mold making, and general plastic casting. It helps buyers improve product detail replication, shorten production cycles, reduce defect rates, and lower long-term manufacturing costs.
Certifications and Compliance
The product holds ISO 9001 quality management system certification and CE certification. The platinum cured mold silicone variant meets FDA standards (Food grade mold silicone, applicable for furniture with food-contact scenarios). All formulations comply with international industrial silicone norms and non-dangerous goods transport standards, ensuring smooth global procurement and customs clearance.
Customization Options
We offer OEM customization services: adjustable hardness (10-30 Shore A), viscosity (for complex furniture textures), curing speed (to match production rhythm), and packaging specifications. We also optimize formulas for enhanced urethane resistance or higher heat resistance, catering to Rapid prototyping silicone needs and large-scale PU furniture production.
Production Process
Manufactured with high-purity silicone raw materials, the process includes: precise formula blending, closed vacuum mixing, multi-index testing (heat resistance, tear strength, shrinkage), and standardized filling. Each batch undergoes pre-production sampling, in-process inspection, and final shipment testing, supported by a professional R&D team and mature production lines, ensuring stable quality for bulk orders.
