Liquid Platinum Silicone Rubber for Jewelry Molds

Ultra-Precise & Safe for Fine Jewelry

Crafted for artisans and luxury manufacturers, our platinum-cured silicone rubber delivers sub-0.02mm detail replication and zero shrinkage, certified skin-safe (ISO 10993-10) and phthalate-free (REACH SVHC). Designed for intricate jewelry casting, it combines:

• Optical Clarity: 92% light transmission (ASTM D1003) to inspect wax/resin prototypes for flaws.

• Thermal Stability: Withstands -40°C to +230°C, perfect for pewter, low-melt metals, and UV resin curing.

• Non-Stick Performance: 10,000+ demolding cycles without talc or release sprays (tested per ASTM D624).

Critical Applications

1. Luxury Jewelry Production:

• Ring & Pendant Molds: Captures filigree, engraving, and micro-textures (e.g., 0.1mm diamond-cut patterns).

• Custom Wax Models: Resists sticking to 3D-printed resin masters, enabling bubble-free wax injections.

2. Artisan Crafting:

• Silicone Clay Molds: Shore A 15–25 softness allows gentle demolding of delicate pieces (e.g., porcelain-like pendants).

• Lost-Wax Casting: Withstands burnout oven cycles (300°C) without deformation or residue.

3. Dual-Use Scenarios:

• Cosmetic & Jewelry Hybrids: Safe for skin-contact items like silicone-embedded gemstone bracelets.

• Dental Jewelry Prototyping: USP Class VI-certified grades for biocompatible oral accessories.

Customization & Compliance

• Tailored Properties:

• Hardness: Shore A 10–40 (±2) for flexibility or rigidity.

• Color: Crystal-clear, frosted, or Pantone-matched tints (ΔE <1.0).

• Additives: Glow-in-the-dark pigments (STR >15 hrs) or conductive fillers for electroforming compatibility.

• Certification Kits: Includes FDA 21 CFR §177.2600 (indirect food contact), EU Toy Safety Directive, and RoHS reports.

• Rapid Prototyping: 48-hour free 250g samples with vacuum degassing support for bubble-free molds.

Supply Chain Assurance

• Precision Manufacturing: Produced in ISO Class 7 cleanrooms with 99.98% purity, validated by third-party SGS tensile (≥5 MPa) and tear tests (≥18 kN/m).

• Global Logistics: Available in 1 kg cartridges, 10 kg kits, or bulk 50 kg drums, with DDP terms and保税仓 inventory for fast APAC/EU delivery.

• Blockchain Traceability: QR-code-enabled batch tracking from platinum catalyst to final cure, ensuring ethical sourcing (RJC-compliant silica).
