Technical Superiority
Our RTV-2 silicone rubber is engineered for high-precision mold replication, utilizing addition-curing (platinum catalyst) and condensation-curing (organotin catalyst) systems to ensure dimensional accuracy (±0.1% shrinkage) and compliance with FDA 21 CFR §177.2600 and BfR XXI for food-contact applications1. Key properties include:
Thermal Resistance: Stable across -50°C to +250°C, with short-term tolerance up to 300°C for automotive and industrial casting resins.
Mechanical Performance: Tensile strength ≥8 MPa, tear resistance ≥25 kN/m, and elongation at break up to 600%, ensuring durability for complex geometries and undercuts.
Certifications: UL94 HB flame retardancy, REACH/RoHS compliance, and ISO 10993-5 cytotoxicity certification for medical-grade tooling.
Precision Applications
Artisan & Industrial Mold Making:
Resin Casting: Replicates <0.2mm surface details for epoxy, polyester, and PU foam molds (e.g., decorative crafts, automotive prototypes).
Food-Grade Molds: Used for chocolate, gummy, and baking molds, compliant with EC 1935/2004 and LFGB standards.
Advanced Manufacturing:
EV Battery Encapsulation: Resists thermal cycling (-40°C to 200°C) and provides dielectric strength ≥15 kV/mm for high-voltage insulation.
Medical Device Prototyping: USP Class VI-certified grades for syringe molds and implantable device tooling.
Customization & Production
Tailored Formulations: Adjust hardness (Shore A 20–55), viscosity (25,000–50,000 mPa·s), or add UV/ozone stabilizers for outdoor applications.
Rapid Prototyping: 72-hour sample delivery with free 500g trials and mold-flow analysis for intricate designs (e.g., micro-textured surfaces).
Dual-Curing Options: Opt for platinum-based (zero byproducts) or tin-catalyzed systems, with adjustable pot life (30 mins to 4 hours).
Supply Chain Assurance
Packaging: Available in 5 kg pails, 25 kg drums, or bulk ISO tanks, with nitrogen inerting to extend shelf life (12+ months).
Global Logistics: DDP terms and for APAC/EU clients, supported by blockchain-tracked batch data.
Quality Guarantee: 36-month material consistency pledge, backed by SGS tensile/tear test reports.
