High Tear Strength Platinum Cure Silicone Rubber 40 Shore A 1:1 19 kN/m Custom OEM for GRC Concrete Molds Manufacturer

Shenzhen Hanast New Material Co., Ltd. is a high tear strength platinum silicone supplier and custom OEM manufacturer specializing in two-component addition-cure RTV silicone rubber for architectural concrete mold making, GRC casting, and high-volume industrial production. Our 40,000-square-meter facility delivers multi-ton batch capacity with consistent quality for construction material factories and precast concrete manufacturers worldwide.

The HN-E40-HT features an exceptional tear strength of 19 kN/m, making it the ideal choice for demanding mold applications that require repeated demolding cycles without edge tearing or mold degradation. Combined with the E-Series full hardness range (0-60 Shore A) and custom OEM formulation service, we provide tailored solutions for every architectural casting requirement.

• 19 kN/m Tear Strength - Industry-leading tear resistance ensures superior durability for repeated demolding cycles in high-volume architectural production, significantly reducing mold replacement frequency and downtime
• Custom OEM Hardness 0-60 Shore A - Full E-Series range supports custom formulations from ultra-soft (Shore 00-0A) to rigid (Shore 60A), matching specific application requirements from flexible decorative molds to structural concrete forms
• 1:1 Simple Mixing Ratio - Accurate equal-part mixing minimizes operational errors, suitable for both manual pouring and automated dispensing systems in industrial environments
• 7.2 MPa Tensile Strength with 330% Elongation - Premium mechanical properties ensure molds withstand heavy concrete loads while maintaining flexibility for easy demolding
• Ultra-Low Shrinkage 0.1% - Ensures precise dimensional accuracy for architectural casting, preserving fine surface details of cultural stone and decorative panels
• Platinum-Catalyzed Non-Toxic System - Generates no curing byproducts, meets RoHS and REACH compliance for unrestricted export to global markets

• Large Concrete Component Molds - Engineered for casting heavy cement architectural elements with precise geometric retention under substantial compressive loads
• GRC Facade Panel Production - High-durability molds for glassfiber reinforced concrete panels, facade elements, and lightweight architectural components
• Concrete Paver & Block Manufacturing - Extended-service-life molds for repetitive commercial paver and tile production with thousands of demolding cycles
• Cultural Stone & Decorative Wall Panels - Exceptional surface detail reproduction with mold longevity for artificial stone production lines
• Epoxy Resin River Tables & Art Pieces - High-gloss surface finish capability for large decorative casting projects
