HONG YE SILICONE High Temperature Resistant Silicone Rubber for Molding is a professional two-component RTV 2 Silicone Rubber, available in Condensation Curing Silicone Mold Rubber and Addition Curing Silicone. As premium Mold Making Silicone and liquid silicone , it features exceptional fluidity, soft texture and room-temperature curing, with high tensile/tear strength and outstanding bubble releasing. It withstands temperatures up to 250℃, supports multiple duplication cycles and easy demolding, ideal for small detailed resin crafts, candle decorations, ceramic figurines and polyurethane products. It meets diverse industrial needs, reducing mold replacement costs and improving production efficiency for global B2B buyers.
Product Overview
This specialized Industrial mold silicone rubber is engineered for high-temperature molding scenarios, designed to maintain stability during casting and curing processes of heat-sensitive materials. It is a two-part room-temperature vulcanization product (Part A: flowable liquid silicone, Part B: curing agent/catalyst), covering two mature systems to balance cost and performance. The soft texture and excellent fluidity enable full filling of intricate mold cavities, making it a top choice for small-size products with detailed patterns. Its high temperature resistance ensures no deformation or aging under heat, suitable for manufacturers of resin crafts, candle decorations and precision small arts and crafts.

Product Features & Advantages
Superior high temperature resistance (up to 250℃) ensures stable performance in heat-intensive molding processes. Exceptional fluidity enables easy pouring and full coverage of fine details on small products. Soft texture (10–30 Shore A) and good flexibility ensure damage-free demolding, even for complex patterns. High tensile and tear strength extend mold service life and support multiple duplication cycles. Outstanding bubble releasing property guarantees smooth mold surfaces and high-quality castings. Room-temperature curing simplifies production without special heating equipment. Dual curing systems offer cost-effective (condensation) and eco-friendly (platinum) options for diverse needs.
How to Use the Product
Step 1: Prepare the prototype and molding frame, fix the prototype firmly; apply a release agent for glass/ceramic prototypes to prevent sticking.
Step 2: Select condensation or addition curing silicone, weigh Part A and Part B according to the recommended ratio, and stir evenly.
Step 3: Perform vacuum defoaming for 1–3 minutes to eliminate air bubbles, then pour the mixed silicone into the frame.
Step 4: Allow room-temperature curing until fully solidified (demoldable after 3–6 hours, full curing in 24 hours).
Step 5: Demold gently and use the mold for high-temperature related casting processes.
Application Scenarios
Widely used for making molds for resin figurines, polyurethane furniture, ceramic figurines, mud figurines, polyester decorations, unsaturated resin crafts, polyresin products, wax, candles, soap and small detailed arts and crafts. Suitable for small resin craft factories, candle decoration manufacturers, ceramic studios and precision small-part molding enterprises. It helps buyers improve product detail accuracy, reduce defective rates via heat stability, and lower production costs through durable mold performance, enhancing market competitiveness.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards. Platinum cured Mold Silicone meets FDA/EU Food grade mold silicone requirements for indirect food contact applications (e.g., candle, soap molds). All formulas conform to international chemical transportation and import regulations, supporting smooth cross-border bulk procurement.
Customization Options
Support customization of hardness (10–30 Shore A), viscosity (adapt to different detail complexity), curing speed and color. Provide formula optimization for ultra-high temperature needs (up to 300℃) or extra-fine pattern molding. Customize packaging specifications (small sample jars to industrial drums) and mixing ratios to match production lines, meeting personalized B2B requirements.
Production Process
Adopt high-purity heat-resistant Silicone raw materials, go through precise proportioning, closed vacuum mixing (to maintain fluidity and avoid bubbles), multi-index testing (high-temperature resistance, hardness, tensile strength), automatic filling and sealed packaging. Each batch undergoes strict quality inspection, with mature production lines ensuring consistent quality and on-time delivery for large orders.
FAQ
Q1: What is the maximum temperature the silicone can withstand?
A1: It can stably withstand up to 250℃, with customizable formulas for ultra-high temperature needs (up to 300℃).
Q2: Which curing system is suitable for me?
A2: Condensation type for cost-sensitive industrial use; platinum type for eco-friendly or food-contact related molds (e.g., soap, candle).
Q3: What hardness is best for detailed small products?
A3: 10–20 Shore A is ideal for capturing fine patterns and easy demolding.
Q4: Do I need a release agent?
A4: Only for smooth non-porous prototypes (glass/ceramic); porous materials (resin, clay) do not require it.
Q5: How long can the silicone be stored?
A5: 12 months when stored in original sealed packages at ≤25℃ in dry, cool places.
