Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam ) is a permanent anti-yellowing transparent core product, specially developed for transparent components, anti-yellowing requirements and high-aesthetic scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with anti-yellowing agents and high-transparency Silicone raw materials, featuring permanent anti-yellowing performance, high light transmittance, fine uniform closed-cell structure, good elasticity and color stability. It has a transmittance of ≥90% and no yellowing after 5000h UV irradiation, can maintain transparent appearance and stable color in long-term use, effectively solving the problem of traditional foaming materials’ easy yellowing and discoloration in light-exposed or long-term use scenarios. Compatible with most of our precision and electronic products, it is ideal for transparent components, high-aesthetic buffers and anti-yellowing scenarios.

2. High Transparency: Transmittance ≥90%, clear and transparent, no turbidity, maintaining aesthetic appearance, suitable for transparent component requirements.
3. Anti-Yellowing & Elasticity Balance: While maintaining permanent anti-yellowing and high transparency, it retains good elasticity and structural stability, no brittle fracture, balancing aesthetic performance and usability.
4. Compatibility with Transparent Products: Compatible with HONG YE SILICONE’s high-precision mold silicone and electronic Potting Compound, forming a complete transparent anti-yellowing solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into transparent components, no professional anti-yellowing or transparent processing skills required, improving production efficiency.
How to Use
1. Take Part A and Part B according to 1:1 weight ratio, stir separately in a clean, dust-free container to eliminate sediment, ensure no impurities (avoid affecting transparency and anti-yellowing performance).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure transparency uniformity and closed-cell structure, avoid turbidity).
3. Pour the mixture into transparent component mold (paired with high-precision mold silicone), foam and cure at room temperature or by heating, avoiding high-temperature over-curing to maintain transparency.
4. After full curing, the product is clear and transparent, with permanent anti-yellowing performance, ready for use in transparent, anti-yellowing and high-aesthetic scenarios.
Application Scenarios
Focus on transparent anti-yellowing scenarios: Consumer electronics transparent buffers (paired with electronic potting compound), optical component packaging (paired with high-precision mold silicone), transparent robot parts (paired with robot silicone), high-aesthetic packaging (paired with Liquid Tank Silicone), and transparent industrial components (paired with Industrial mold silicone rubber). It helps high-aesthetic buyers maintain product appearance and extend the service life of transparent components.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS anti-yellowing certification, SGS transparency certification, excellent permanent anti-yellowing and high-transparency performance, meeting the anti-yellowing and transparent procurement requirements of B2B buyers in consumer electronics, optical and high-aesthetic industries, facilitating export to global markets.
Customization Options
Customizable anti-yellowing duration (no yellowing after 8000h UV irradiation for high-demand scenarios), transparency level (transmittance ≥95% for high-demand scenarios), foaming ratio and hardness, adapting to different transparent and anti-yellowing requirements, helping buyers optimize product aesthetic and service life.
Production Process
Anti-yellowing transparent-oriented production process: High-purity high-transparency silicone raw materials → formula optimization (add permanent anti-yellowing agents) → precision mixing in dust-free workshop → anti-yellowing test (5000h UV irradiation) → transparency test → standardized curing → color stability inspection → packaging. Strict anti-yellowing and transparency testing ensures product clear appearance and long-term anti-yellowing performance.
