Premium Platinum Cure Liquid Silicone Rubber

Shenzhen Hanast New Material Co., Ltd. is a direct factory manufacturer and bulk supplier of premium platinum cure liquid silicone rubber specifically formulated for high-precision jewelry mold making, food-grade chocolate molds, and architectural tile molds. With a production capacity of 100 tons per month and over a decade of silicone R&D expertise, we serve jewelry manufacturers, confectionery producers, and precision casting workshops worldwide.

This RTV-2 platinum-cured liquid silicone rubber (Model HN-E30) features ultra-low shrinkage for exceptional detail reproduction, a simple 1:1 mixing ratio for operator-friendly handling, and adjustable 30-40 minute working time for careful, accurate molding. FDA, RoHS, and REACH certified, it meets the strictest international safety and environmental standards. Available with MOQ from just 1 Kg and free 1 Kg trial samples for performance evaluation before bulk procurement.

Key Features for Jewelry & Precision Molding
  • Ultra-Low Shrinkage – Proprietary platinum-cured formulation ensures minimal dimensional change during curing, capturing intricate jewelry details, filigree patterns, and complex surface textures with superior fidelity
  • Tensile Strength ≥6.5 MPa – Robust mechanical properties ensure finished molds withstand repeated demolding cycles without tearing or deformation, delivering long service life in production environments
  • 1:1 Easy Mixing Ratio – Simple equal-part A:B mixing eliminates complex calculations and reduces operator error, ensuring consistent batch quality for both manual and automated dispensing
  • FDA Food-Grade Compliant – Non-toxic platinum-catalyzed curing system is fully FDA compliant for direct food contact, making it ideal for chocolate molds, confectionery molds, and baking applications
  • Adjustable Working Time 30-40 min – Generous pot life provides ample time for mixing, degassing, and precise pouring into intricate mold cavities without premature curing
  • Fast 3-4 Hour Demold Time – Room-temperature curing within 3-4 hours supports rapid production cycles and quick turnaround for custom mold orders
  • Customizable Viscosity 800-20000 cps – Wide viscosity range allows tailoring from ultra-thin pour for fine detail capture to thicker consistency for vertical surface application
  • Translucent with Custom Color Option – Default translucent formulation enables easy visual inspection of mold quality with optional custom pigmentation available for OEM partners
Precision Application Fields
  • Jewelry Mold Making – Perfect for capturing intricate ring, pendant, bracelet, and ornament patterns with sub-millimeter precision. The ultra-low shrinkage formula preserves every fine detail from wax prototypes to production molds
  • Food-Grade Chocolate & Confectionery Molds – FDA-compliant, non-toxic formulation safe for direct food contact. Ideal for customized chocolate bars, pralines, cake decorations, and artisan confectionery production
  • Wall Tile & Architectural Decorative Molds – High tensile strength and deformation resistance for crafting intricate wall tile molds, decorative panels, and architectural ornament components with clean, sharp detailing
  • Precision Prototype Casting – Excellent flowability and detail capture for product development, rapid prototyping, and small-batch production across multiple industries
  • Resin Art & Craft Molds – Superior surface finish and easy demolding for epoxy resin jewelry, coasters, decorative items, and artisan craft products
