Product details

HONG YE SILICONE Silicone Rubber for Rapid Prototyping is a premium two-component addition curing silicone, featuring high transparency mold silicone properties and a 1:1 mixing ratio. As core rapid prototyping silicone, it supports both room-temperature and heat curing, with linear shrinkage ≤0.1% and no small-molecule release during crosslinking. Certified as food grade mold silicone (FDA approved), it is non-toxic, tasteless, and resistant to 300-500℃. With excellent fluidity, tensile strength, and tear resistance, it ensures precise detail replication and multiple molding cycles, ideal for prototyping epoxy resin, auto parts, and cement components, meeting global B2B procurement demands for efficiency and precision.

Product Overview

This silicone is a professional rapid prototyping silicone designed for high-precision mold making, belonging to our addition curing silicone product line. Crafted with premium silicone raw materials, it boasts high transparency—its clear base ensures molds are transparent enough to observe internal details, a key requirement for prototype verification. As a platinum cured mold silicone variant, it adopts a 1:1 mixing ratio of Component A and B, enabling easy operation and flexible curing (room temperature or elevated temperature). It solves core pain points like dimensional deviation and poor detail replication in prototyping, making it a reliable choice for global manufacturers.

Product Features & Advantages

It offers ultra-low shrinkage (≤0.1%) with no small-molecule release during crosslinking, ensuring stable volume and precise prototype dimensions. As high transparency mold silicone, it allows real-time observation of internal details, reducing prototype defects. Certified food grade (FDA approved), it is non-toxic and tasteless, suitable for food-contact or medical-related prototypes. It supports dual curing methods (room temperature/heating), flexible for different production rhythms. With excellent high-temperature resistance (300-500℃), it adapts to harsh prototyping environments. Good fluidity enables easy pouring, while high tensile and tear strength extend mold service life and increase molding cycles, reducing procurement costs.

Usage Instructions

Step 1: Prepare clean tools (avoid contact with condensation curing silicone mold rubber residues) and mix Component A and B in a 10:1 weight ratio, stirring evenly.

Step 2: Perform vacuum defoaming on the mixture to eliminate bubbles for smooth molding.

Step 3: Pour the mixture into the prototype master mold, ensuring full coverage of fine details.

Step 4: Cure at room temperature (3-4 hours) or heat (60-120℃, 10-60 minutes) as needed.

Step 5: Conduct a small test on the mold blank first to confirm curing effect before mass prototyping. Step 6: Demold gently after full curing to obtain the prototype mold.

Application Scenarios

Widely used for casting epoxy resin, polyester resin, polystyrene, vinyl plastic, paraffin, large cement components, and cultural stone. It is also ideal for precision die casting of auto parts, ship parts, tire aluminum molds, and tire precision molds. Suitable for automotive, construction, craft, and industrial prototyping industries, it helps buyers accelerate prototype development, improve molding accuracy, reduce defect rates, and cut production and time costs.

Certifications and Compliance

The product holds FDA food grade certification, complying with food-contact safety standards. It also meets ISO 9001 quality management system certification and CE certification, aligning with international industrial silicone norms. All formulations are non-toxic and eco-friendly, ensuring smooth customs clearance and safe application in global markets.

Customization Options

We provide OEM customization services, supporting adjustments to key parameters such as silicone hardness, viscosity, curing speed, and transparency. Whether for small-batch prototype testing or large-scale production, we can tailor solutions to match buyers’ specific prototyping materials (e.g., resin, cement) and process requirements.

Production Process & Quality Control

The production process includes high-purity silicone raw materials screening, precise formula blending, closed vacuum mixing, transparency and performance testing, and standardized filling. Each batch undergoes pre-production sampling, middle-stage inspection, and final shipment testing. With mature production lines and a professional QC team, we ensure consistent product performance and stable supply capacity for global bulk orders.
