Ultra-Precise Mold Engineering
Our platinum-cured RTV-2 silicone rubber redefines mold-making accuracy with <0.1% linear shrinkage and sub-0.05mm detail replication, certified for both FDA 21 CFR §177.2600 (food contact) and ISO 10993-5 (medical devices). Utilizing a two-component addition-curing system, it eliminates toxic byproducts (vs. tin-catalyzed RTV) while achieving:
Temperature Resilience: Stable from -50°C to +250°C (short-term 300°C), ideal for epoxy, polyurethane, and low-melt metal casting.
Mechanical Strength: Tensile strength ≥7.5 MPa, tear resistance ≥22 kN/m, and elongation up to 650% for deep undercut demolding.
Chemical Resistance: Immersion-tested in IPA, acetone, and alkaline cleaners (pH 12) with no surface degradation.
Industry-Specific Applications
Medical & Dental:
Prosthetic Socket Molds: Shore A 10–15 softness replicates skin textures while withstanding sterilization (autoclave/EtO).
Dental Impression Trays: Odorless, tasteless formulation compliant with ADA guidelines.
Food-Grade Tooling:
Chocolate & Confectionery Molds: LFGB-certified, 10,000+ release cycles without demolding agents.
Baking Mat Production: Non-stick surface passes EC 1935/2004 migration tests.
Advanced Manufacturing:
EV Battery Encapsulation: UL94 V0 flame retardancy and dielectric strength ≥14 kV/mm.
Aerospace Prototyping: Resists jet fuel exposure (MIL-SPEC testing) and thermal cycling (-55°C to 200°C).
Customization & Workflow Optimization
Dual Hardness Systems: Layer Shore A 05 (surface) over Shore A 40 (structural base) for hybrid flexibility/durability.
Cure Control: Adjust pot life (20–90 mins) and demold time (4–12 hrs) via catalyst ratios.
Functional Additives: UV stabilizers, conductive fillers (0.01–10³ Ω·cm), or Pantone-matched pigments.
Supply Chain Assurance
Rapid Prototyping: 48-hour free 1kg samples with 3D-printed mold validation for complex geometries.
Certified Production: Manufactured in ISO Class 7 cleanrooms, supported by SGS reports on tear strength and biocompatibility.
Global Traceability: Blockchain-tracked batches with QR code access to viscosity curves and cure profiles.
