HONG YE SILICONE Silicone Rubber with High Temperature Tolerance is a premium two-component RTV 2 Silicone Rubber, adopting Platinum cured mold silicone formula (platinum catalyst curing agent). It withstands extreme temperatures (-60℃ to 200℃), features almost nil shrinkage, high tear strength and chemical resistance. As FDA-approved Food grade mold silicone, it’s non-toxic, odorless, and offers exceptional fluidity for easy operation. Suitable for rapid prototyping, GRC/concrete molding, PU resin casting and food mold making, it ensures high precision replication and long-term dimensional stability, reducing mold replacement costs for global B2B buyers.
Product Overview
This professional Industrial mold silicone rubber is engineered for high-temperature and harsh environment applications, composed of flowable liquid Part A and platinum catalyst Part B. As a core Addition Curing Silicone product, it integrates high temperature resistance, low shrinkage and food-grade safety, solving pain points like deformation, curing failure and poor durability in traditional mold making. With excellent operability and precision replication, it’s widely trusted in rapid prototyping, construction decoration and food processing industries, balancing performance and safety for diverse manufacturing needs.

Product Features & Advantages
It boasts wide temperature tolerance (-60℃ to 200℃) for stable performance in extreme environments. Almost nil shrinkage and high dimensional stability ensure consistent precision replication. High tear strength enhances wear and shear resistance, extending mold service life. FDA-approved food grade certification guarantees non-toxic, odorless and eco-friendly properties for food contact applications. Exceptional fluidity and operability simplify pouring and molding, reducing labor costs. High chemical resistance avoids corrosion from aggressive resin components. Compared to tin-cured variants, it offers superior stability and no curing inhibition (with proper operation), ensuring batch consistency. Fine non-sticky surface facilitates easy demolding and mold cleaning.
How to Use
Step 1: Thoroughly clean the master model and molding tools to avoid curing inhibition.
Step 2: Weigh Part A and Part B according to 1:1/10:1 ratio, ensuring accurate proportioning.
Step 3: Stir the two components thoroughly to form a uniform mixture.
Step 4: Vacuum-pump the mixture for 2-3 minutes to remove bubbles (for no vacuum machine, pour slowly along the mold frame).
Step 5: Enclose the master model with plastic/wooden plates and apply release agent (detergent/soap water) on the model.
Step 6: Pour the bubble-free mixture into the mold frame from the side.
Step 7: Wait for full room-temperature curing, then demold to get the finished mold.
Application Scenarios
Widely used for rapid prototyping (urethane casting, silicone tooling, vacuum casting), GRC and concrete molding, PU resin casting, general mold making and food grade mold applications (chocolate, candy, etc.). It also fits Prototype silicone , Toy mold silicone and construction decoration mold production. It helps buyers improve production efficiency, ensure product consistency, and reduce mold replacement costs, especially for high-temperature or food-contact manufacturing.
Certifications and Compliance
The product holds ISO 9001 quality management system certification, CE safety certification and FDA food grade certification. It complies with international industrial silicone standards and food safety norms, ensuring smooth global procurement and customs clearance for B2B buyers.
Customization Options
We offer OEM customization services, including adjustable hardness, viscosity, curing speed and color. We also optimize formulas for higher temperature resistance (beyond 200℃) and adjust mixing ratios, catering to Rapid prototyping silicone needs and large-scale industrial production requirements.
Production Process
Manufactured with high-purity Silicone raw materials, the product undergoes precise formula blending, closed vacuum mixing, multi-index testing (temperature resistance, shrinkage, tear strength) and standardized filling. Each batch is strictly inspected before shipment, supported by professional R&D teams and mature production lines, ensuring stable quality for bulk orders.
