Hong Ye Addition Cure Mold Making Silicone Rubber

Hong Ye Addition Cure Mold Making Silicone Rubber is a premium two-component platinum-cured liquid silicone rubber specifically engineered for high-precision mold making applications. Manufactured by Shenzhen Hong Ye Jie Technology Co., Ltd. with 18 years of industry expertise, this RTV-2 silicone delivers exceptional flowability, ultra-low shrinkage, and outstanding tear resistance — making it the preferred choice for professional mold makers, artisans, and manufacturers worldwide.① Exceptional Detail Reproduction
Our low-viscosity formula flows freely and self-levels, capturing intricate details down to 0.01mm with remarkable precision. Whether it's facial features, hair strands, or delicate surface textures, every fine detail is faithfully reproduced, delivering molds that match the original model with 99%+ accuracy.

② Extended Mold Life & High Durability
Formulated with high-quality vinyl silicone oil and premium platinum catalyst, the cured silicone elastomer exhibits exceptional tear strength (up to 35 kN/m) and excellent elongation at break (400-800%). A single mold can withstand 100-300+ casting cycles without cracking, deforming, or losing detail — significantly reducing mold production costs.

③ Ultra-Low Shrinkage for Dimensional Stability
The addition cure process ensures no low-molecular byproducts are released during curing, resulting in linear shrinkage as low as 0.05%-0.1%. This remarkable dimensional stability makes it ideal for precision casting applications where tight tolerances are critical.

④ Wide Temperature & Material Compatibility
With a service temperature range from -60°C to +250°C, this silicone withstands repeated thermal cycling. It is compatible with a wide range of casting materials including polyester resin, epoxy resin, polyurethane, gypsum, cement, wax, soap, and more — one mold serves multiple purposes.

⑤ User-Friendly & Easy to Work With
Simple 1:1 mix ratio by weight, room temperature curing without heating required. Working time ranges from 30-120 minutes (customizable), with full cure in 2-4 hours. Self-degassing properties ensure minimal bubbles, and vacuum degassing achieves professional results.
