HONG YE SILICONE Silicone Rubber for Rapid Prototyping is a high-performance two-component Addition Curing Silicone, widely recognized as Rapid prototyping silicone and Platinum cured mold silicone. This liquid silicone and Mold Making Silicone features a 1:1 mixing ratio, supporting both room-temperature and elevated-temperature curing. With ultra-low shrinkage (≤0.1%), High transparency mold silicone quality, FDA-certified food grade safety, and excellent high-temperature resistance (300-500℃), it is ideal for precision prototyping of auto parts, tire molds, resin casting and industrial components. It helps global B2B buyers shorten prototype development cycles, improve molding precision and reduce trial production costs.
Product Overview
This specialized silicone rubber is engineered for efficient, high-precision rapid prototyping, adopting an addition curing system that avoids small molecule release during crosslinking, ensuring stable volume and dimensional accuracy. Its crystal-clear silicone base delivers high transparency, allowing clear observation of internal details during molding, which is critical for precision prototype inspection. The simple 1:1 mixing ratio simplifies operation, requiring no professional skills, while flexible curing modes (room temperature or heating) adapt to different production rhythms. It is compatible with various casting materials, making it a versatile solution for industrial prototyping and small-batch trial production.

High transparency allows real-time observation of internal molding details, reducing defective prototypes. Deep curing ability, not limited by mold thickness, suitable for both small precision parts and large components. Excellent high-temperature resistance adapts to high-temperature casting processes and materials. Food grade, non-toxic and odorless, passing FDA certification for safe use in diverse scenarios. High tensile and tear strength extends mold service life, supporting multiple repeated molding cycles. Good fluidity enables easy pouring and full filling of complex prototype details. 1:1 mixing ratio and flexible curing modes simplify operation, improving prototyping efficiency.
How to Use the Product
Step 1: Prepare clean tools and containers, ensuring they have not been used with condensation curing silicone rubber to avoid curing failure.
Step 2: Mix Part A and Part B at a 1:1 weight ratio, stir evenly for 2-3 minutes to ensure full integration.
Step 3: Perform vacuum defoaming for 1-2 minutes to eliminate air bubbles generated during mixing.
Step 4: Pour the mixed silicone into the prototype mold slowly, ensuring all details are fully covered.
Step 5: Choose curing mode: cure at 25℃ for 3-4 hours, or heat at 60-120℃ for rapid curing (10-60 minutes).
Step 6: Conduct a small-scale test on the mold base before formal mass prototyping to confirm curing effect.
