HONG YE SILICONE Translucent Silicone Rubber for Mold is a high-performance two-component RTV 2 Silicone Rubber, available in tin-based condensation curing silicone and Platinum cured mold silicone. As professional Mold Making Silicone and liquid silicone , it features exceptional fluidity, low linear shrinkage and high mechanical strength, with mixing ratios of 100:3 (tin-based) and 1:1/10:1 (platinum-based). Its translucent property enables visual casting monitoring, ideal for high-precision prototyping, automotive parts molding and Food grade mold silicone applications (chocolate, cake). It supports repeated use, easy demolding and stable performance, helping buyers improve production accuracy and reduce mold costs.
Product Overview
This specialized Industrial mold silicone rubber is engineered for high-precision molding, with unique translucency to observe internal filling and bubble formation during casting. It is a two-part room-temperature vulcanization product (Part A: flowable liquid silicone, Part B: curing agent), covering tin-catalyzed and platinum-catalyzed systems. The platinum-based version meets food grade standards, while the tin-based offers cost-efficiency for industrial use. With excellent flexibility and tear strength, it perfectly replicates fine details of prototypes and crafts, supporting pouring molding for complex shapes. It is compatible with plaster, resin, PU, wax and stone materials, serving as a versatile solution for precision manufacturing and craft production.

Product Features & Advantages
Translucent design allows real-time observation of filling status, reducing bubble and incomplete filling defects. Excellent fluidity ensures full coverage of complex mold cavities, capturing ultra-fine details. High tensile and tear strength extends mold service life and duplication cycles. Low linear shrinkage guarantees dimensional accuracy of cast products. Flexible texture enables easy demolding without damaging delicate parts. Platinum-based version is food-safe and eco-friendly, meeting international food contact standards. High temperature resistance adapts to various casting material requirements. Multiple curing agent options adjust operation and curing time for different applications.
How to Use the Product
Step 1: Prepare the prototype and molding frame, fix the prototype in the frame. Apply release agent if the prototype is glass/ceramic to prevent sticking.
Step 2: Select tin-based or platinum-based silicone, weigh Part A and Part B according to the recommended ratio, stir evenly.
Step 3: Perform vacuum defoaming for 1-3 minutes, inject the mixed silicone into the mold box, and conduct secondary defoaming if needed.
Step 4: Cure at room temperature for 3 hours, then demold; place the mold in the same environment for 24 hours to stabilize before use.
Step 5: Proceed with casting (resin, food, plaster) and monitor filling via translucent mold if necessary.
Application Scenarios
Widely used for high-precision prototyping (Rapid prototyping silicone), automotive parts molding, food molding (chocolate, cake, candy) with platinum-based food grade Mold Silicone . It is also suitable for plaster decoration duplication, gypsum sculpture reproduction, resin/PU/wax/stone product replication and polyester craft molding. Ideal for precision manufacturing enterprises, craft workshops, food processing plants and automotive parts suppliers. The translucent feature improves casting success rate, while high duplication times reduce production costs and enhance market competitiveness.
Certifications and Compliance
The product complies with ISO 9001 quality management system and CE industrial standards. Platinum-based silicone meets FDA and EU food contact safety regulations. All formulas conform to international chemical transportation and import requirements, supporting smooth cross-border B2B bulk procurement and market access.
Customization Options
Support customization of hardness (20-40 Shore A), translucency level, viscosity (adapt to complex/simple molds) and curing speed. Provide formula optimization for special scenarios (e.g., ultra-high precision prototyping, large automotive parts). Customize packaging specifications (small sample jars to industrial drums) and mixing ratios according to buyer production needs.
Production Process
Adopt high-purity Silicone raw materials, go through precise proportioning, closed vacuum mixing (to maintain translucency and avoid impurities), multi-index testing (translucency, tensile strength, shrinkage rate), automatic filling and sealed packaging. Each production link is strictly quality-controlled, with mature lines ensuring consistent batch quality and on-time delivery for large orders.
FAQ
Q1: What is the advantage of translucent silicone?
A1: It allows visual monitoring of casting filling and bubble formation, reducing defective products and improving production efficiency.
Q2: Is the platinum-based version safe for food contact?
A2: Yes, it meets food grade mold silicone standards (FDA/EU certified) for chocolate, cake and candy molding.
Q3: How to choose the mixing ratio?
A3: Tin-based (100:3) for cost-sensitive industrial use; platinum-based (1:1/10:1) for food contact or high-precision applications.
Q4: Do I need a release agent for all prototypes?
A4: Only for smooth surfaces like glass/ceramic; porous prototypes (plaster, resin) do not require it.
Q5: Can it be used for large automotive parts?
A5: Yes, we provide viscosity and hardness customization to adapt to large-size mold making and ensure stable performance.
