Product Features & Advantages
1. Ultra-Low Linear Shrinkage: Shrinkage rate ≤0.3%, far lower than industry average (≥0.8%), ensuring precise product size after molding, no deformation or dimensional deviation, reducing production waste for precision molding buyers.
2. Stable Precision Molding: Fine uniform pores and stable foaming effect, ensuring consistent molding effect of each product, especially suitable for small-sized, high-precision filling and molding (paired with high transparency mold silicone).
3. High Compatibility with Precision Molds: Perfectly compatible with HONG YE SILICONE’s high transparency mold silicone and platinum cured mold silicone, ensuring mold release smoothness and product precision, avoiding mold sticking and product damage.
4. Easy Precision Operation: 1:1 simple mixing ratio, good flowability, easy to fill into small and complex precision molds, no professional precision equipment required, reducing operation difficulty.
5. Safety & Durability: Passed SGS certification, non-toxic, odorless, -65℃-200℃ temperature resistance, no aging or deformation after long-term use, ensuring precision performance of finished products.
How to Use
1. Take Part A and Part B in 1:1 weight ratio, stir separately to ensure no sediment or impurities (avoid affecting precision).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove tiny air bubbles (ensure molding precision).
3. Slowly pour into precision mold (paired with high transparency mold silicone), avoid air bubbles entering, foam and cure at room temperature or 70℃.
4. After full curing, demold gently, the product size is precise, no need for secondary trimming.
Application Scenarios
Focus on precision molding scenarios: Precision electronic component filling (paired with Electronic Potting Compound), small-sized silicone parts molding (paired with high transparency mold silicone), precision medical auxiliary parts (paired with Medical Grade Body Silicone), high-precision robot components (paired with robot silicone), and small precision cushion parts (paired with platinum cured mold silicone). It helps buyers improve product precision and qualification rate.
Certifications and Compliance
Passed SGS eco-toxicity certification, fully compliant with RoHS international environmental standards, meeting the precision product procurement requirements of B2B buyers in electronic, medical and robot industries, facilitating export to global high-end precision markets.
Customization Options
Customizable shrinkage rate (minimum ≤0.2%), foaming density, viscosity and operation time, adapting to different precision molding requirements of various products, ensuring each customized product meets precision standards.
Production Process
Precision-oriented production process: High-purity Silicone raw materials → formula optimization (reduce shrinkage) → precision mixing (error ≤0.1%) → foaming precision test → standardized curing → dimensional precision inspection → packaging. Strict precision control in each link ensures product ultra-low shrinkage and stable precision.
