Product Features & Advantages
It provides excellent heat resistance to withstand exothermic heat released during PU casting. High thermal conductivity promotes even heat distribution and stable curing. It offers outstanding resistance to common casting resins, with improved protection against urethane and concrete erosion. Great fluidity ensures full filling of complex furniture patterns and easy operation. High tear strength and enhanced durability extend service life and support high duplication cycles. Nil shrinkage maintains long-term dimensional stability for consistent product size. Compared with general mold making silicone, it has targeted modification for PU systems, lowering failure rates and maintenance costs.
How to Use
Step 1: Clean and dry the master model of furniture to remove dust, grease or residual chemicals.
Step 2: Take the base silicone and matching curing agent in the specified ratio, then weigh accurately.
Step 3: Mix the two components fully and evenly until no color streaks or uneven texture appears.
Step 4: Conduct vacuum defoaming to eliminate trapped air for smooth, bubble-free mold surfaces.
Step 5: Pour or brush the mixed silicone onto the master model based on product structure and size.
Step 6: Leave the silicone to complete room temperature vulcanization without external disturbance.
Step 7: Demold carefully after full curing; the mold is ready for PU furniture casting and mass production.
Application Scenarios
Core application: PU furniture molding for various panel, decorative and structural furniture parts. Also used in architectural restoration, sculpting, wax casting, concrete/GRC casting, gypsum and plaster decoration, resin crafts molding, general furniture molding, tire molding, low melting alloys, ceramics mold making, candles mold making and general plastic casting. It helps manufacturers improve product consistency, reduce mold replacement frequency, shorten production cycles and lower overall manufacturing costs.
Certifications and Compliance
This series meets ISO 9001 quality management system standards and CE industrial safety requirements. The platinum cured Mold Silicone variant complies with eco-friendly and low-toxicity production norms, matching import and usage regulations of major global furniture and industrial material markets, supporting smooth bulk procurement and cross-border logistics.
Customization Options
We provide OEM and formula customization services, including adjustable hardness, viscosity, operating time and curing speed. Mixing ratios can be optimized for different production lines, and fluidity or surface hardness can be tuned for complex carved furniture parts, adapting to both small-batch Prototype silicone and large-scale industrial manufacturing.
Production Process
Produced with high-purity Silicone raw materials, the product goes through precise component proportioning, closed vacuum mixing, performance testing (tear strength, heat resistance, shrinkage), and standardized packaging. Each batch undergoes pre-delivery inspection to ensure stable performance, with mature production lines supporting large-volume orders and on-time supply.
FAQ
1. Which catalyst system is better for PU furniture?
Platinum cured mold silicone offers higher heat and PU resistance for long-run production; tin-cured condensation type is cost-efficient for small-batch work.
2. How to ensure nil shrinkage in long-term use?
Stable molecular structure and premium formulation eliminate volume change, maintaining precision for repeated casting.
3. What is the correct storage condition?
Store in unopened packages at or below 32°C in a dry, shaded environment for 12-month validity.
4. Can this silicone be used for resin and gypsum molds?
Yes, it has wide resin resistance and fits most decorative and industrial casting materials.
5. Does high thermal conductivity affect molding quality?
It accelerates heat dissipation during PU casting, reducing mold damage and improving surface quality of finished parts.
