Description
Platinum Cure Silicone Rubber - Architectural Concrete Mold 40 Shore A
Shenzhen Hanast New Material Co., Ltd. is a direct factory manufacturer and bulk supplier of high-performance platinum cure silicone rubber specifically engineered for architectural concrete molds, GRC (Glassfiber Reinforced Concrete) casting, and cultural stone production. With a 40,000-square-meter production base and multi-ton batch capacity, we serve construction material factories, precast concrete manufacturers, and architectural ornament producers worldwide.
This 40 Shore A addition-cure RTV silicone rubber features the industry-standard 1:1 equal-part mixing ratio, exceptional 25 kN/m tear strength, and ultra-low shrinkage rate of ≤0.1%, ensuring precise mold reproduction and superior dimensional accuracy for large-scale architectural casting projects. Available for bulk wholesale supply with custom hardness formulations across the full E-Series range (0-60 Shore A).
Key Features for Architectural & GRC Applications
  • Optimal 40 Shore A Hardness – Provides the ideal balance of rigidity and flexibility for large concrete molds, preventing deformation under heavy material loads during cement and concrete casting
  • Exceptional Tear Strength 19 kN/m – Superior durability for repeated demolding cycles in high-volume architectural production settings, reducing mold replacement frequency
  • Ultra-Low Shrinkage ≤0.1% – Ensures precise mold reproduction and superior dimensional accuracy for architectural casting, preserving fine surface details of cultural stone and decorative panels
  • 1:1 Simple Mixing Ratio – Accurate two-part mixing with minimal room for error, suitable for both manual pouring and automated dispensing systems in industrial production environments
  • Wide Temperature Range -40℃ to +230℃ – Stable performance across extreme conditions, suitable for cold climate outdoor casting and high-temperature resin applications
  • High Transparency – Translucent formulation enables easy visual monitoring of mold quality and allows color pigmentation per customer specifications
  • Non-Toxic & Eco-Friendly – Platinum-catalyzed curing system generates no byproducts, meets RoHS and REACH environmental compliance standards for export markets
  • E-Series Full Hardness Range 0-60 Shore A – Custom formulations available to match specific application requirements, from ultra-soft prosthetics to rigid industrial molds
Architectural & Industrial Applications
  • Large Concrete Component Molds – Engineered for casting heavy cement and concrete architectural elements, maintaining precise geometric shape even under substantial compressive loads
  • Architectural Cultural Stone Casting – Perfect for producing artificial cultural stone, decorative wall panels, and architectural ornaments with exceptional surface detail reproduction
  • GRC (Glassfiber Reinforced Concrete) Molds – High-durability molds designed for GRC panel production, facade elements, and lightweight architectural components
  • High-Gloss Epoxy Resin Casting – Suitable for large epoxy resin river tables, decorative ornaments, and art pieces requiring mirror-finish surfaces
  • Plaster & Sandstone Relief Molds – Multi-piece brush-on molding for flat or large three-dimensional components exceeding 50 cm with moderate pattern complexity
  • Concrete Paver & Paver Production – Long-life molds for repetitive concrete paver, block, and tile manufacturing in commercial production environments
