Product Overview
HONG YE SILICONE’s Liquid Foamed Silicone (Foaming Silicone Rubber, Silicone Foam) is an anti-mildew & moisture-absorbing moisture-proof core product, specially developed for humid environments, storage packaging and moisture-proof scenarios. As a 2-component addition curing silicone, it is formed by chemical foaming of flowable Part A and Part B, formulated with anti-mildew agents and moisture-absorbing fillers, featuring ultra-strong anti-mildew performance, moisture absorption, fine uniform closed-cell structure, good elasticity and moisture stability. It achieves mildew resistance grade 0 (no mildew growth) and moisture absorption rate ≥15%, effectively inhibiting mildew growth and absorbing moisture, solving the problem of traditional foaming materials’ mildew and moisture accumulation in humid scenarios. Compatible with most of our moisture-proof products, it is ideal for anti-mildew components, moisture-absorbing buffers and moisture-proof scenarios.

2. Effective Moisture Absorption: Moisture absorption rate ≥15%, effectively absorbing moisture in humid environments, preventing moisture accumulation and damage to equipment/products.
3. Anti-Mildew & Elasticity Balance: While maintaining strong anti-mildew and moisture absorption, it retains good elasticity and structural stability, no brittle fracture, balancing moisture-proof function and usability.
4. Compatibility with Moisture-Proof Products: Compatible with HONG YE SILICONE’s liquid tank silicone and industrial Mold Silicone rubber, forming a complete moisture-proof solution, enabling one-stop procurement. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into anti-mildew and moisture-absorbing components, no professional moisture-proof operation skills required, improving production efficiency.
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 anti-mildew and moisture absorption).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure uniform anti-mildew and moisture absorption, no moisture accumulation).
3. Pour the mixture into anti-mildew component mold (paired with liquid tank silicone), foam and cure at room temperature or by heating (heating helps enhance moisture stability).
4. After full curing, test mildew resistance (grade 0) and moisture absorption rate (≥15%) to confirm qualification, then use in humid and moisture-proof scenarios.
Application Scenarios
Focus on moisture-proof scenarios: Humid environment anti-mildew buffers (paired with liquid tank silicone), storage packaging moisture-absorbing parts (paired with industrial mold silicone rubber), moisture-proof packaging (paired with liquid tank silicone), humid area machinery components (paired with high-precision mold silicone), and anti-mildew robot parts (paired with robot silicone). It helps humid environment and storage industry buyers inhibit mildew and prevent moisture damage.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS anti-mildew & moisture absorption test certification, excellent anti-mildew and moisture absorption performance, meeting the moisture-proof procurement requirements of B2B buyers in humid environment, storage and moisture-proof industries, facilitating export to global markets.
Customization Options
Customizable mildew resistance grade (0 grade for harsh humid environments), moisture absorption rate (≥20% for high-demand scenarios), foaming ratio and hardness, adapting to different humid and moisture-proof requirements, helping buyers optimize anti-mildew and moisture absorption effect.
Production Process
Anti-mildew moisture-absorbing-oriented production process: High-purity anti-mildew Silicone raw materials → formula optimization (add anti-mildew agents and moisture-absorbing fillers) → precision mixing → anti-mildew test → moisture absorption test → standardized curing → moisture stability inspection → packaging. Strict anti-mildew and moisture testing ensures product anti-mildew performance and moisture absorption.
