Product Summary
Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a low-viscosity core product, focusing on complex mold filling and tiny gap filling. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with low-viscosity components, featuring ultra-low viscosity, excellent fluidity, fine uniform pores and stable performance, which can easily flow into complex and tiny mold gaps, ensuring full filling. Compatible with most of our core products, it is ideal for complex mold molding, tiny gap filling and rapid prototyping.

Product Features & Advantages
1. Ultra-Low Viscosity & Good Fluidity: Viscosity 500-1000 mPa·s, ultra-low viscosity, excellent fluidity, can easily flow into complex mold structures and tiny gaps (≥0.1mm), ensuring full filling, solving the problem of traditional foaming materials’ poor fluidity and incomplete filling.
2. Complex Mold Adaptability: Suitable for various complex molds, including irregular shapes, tiny gaps and thin-walled structures, full filling without dead corners, ensuring consistent molding effect of complex products.
3. Low Viscosity & Performance Balance: While maintaining ultra-low viscosity, it retains good elasticity and durability, fine uniform pores, no collapse or deformation after curing, ensuring product performance of complex mold products.
4. Mold Compatibility: Compatible with HONG YE SILICONE’s high transparency Mold Silicone and rapid prototyping silicone, forming a complete complex mold filling solution, enabling one-stop procurement for complex mold buyers.
5. Easy Complex Filling Operation: 1:1 simple mixing ratio, good fluidity, no additional pressure required for filling, easy to operate, reducing complex mold filling difficulty and production waste.
How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately to eliminate sediment, ensure no impurities (avoid affecting fluidity and filling effect).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure filling uniformity and product performance).
3. Pour the mixture into complex mold or tiny gap (paired with high transparency mold silicone), rely on its own fluidity to fill fully, foam and cure at room temperature or by heating.
4. After full curing, demold gently, the product is fully filled, no missing corners, ready for use directly.
Application Scenarios
Focus on complex mold filling scenarios: Complex electronic component filling (paired with Electronic Potting Compound), tiny gap sealing (paired with Industrial mold silicone rubber), complex transparent product molding (paired with high transparency mold silicone), rapid prototyping of complex parts (paired with rapid prototyping silicone), and complex robot components (paired with robot silicone). It helps complex mold buyers improve product molding quality and reduce filling defects.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, excellent low viscosity and fluidity, meeting the complex mold filling procurement requirements of B2B buyers in various industries, facilitating export to global complex mold markets.
Customization Options
Customizable viscosity (300-1500 mPa·s adjustable), foaming ratio, curing time and pore size, adapting to different complex mold and tiny gap filling requirements, helping buyers optimize filling effect.
Production Process
Low-viscosity-oriented production process: High-purity low-viscosity Silicone raw materials → formula optimization (enhance fluidity) → precision mixing → viscosity and fluidity test → standardized curing → filling effect inspection → packaging. Strict viscosity control ensures product good fluidity and complex mold filling performance.
