Product Features & Advantages
1. Excellent Transparency: Light transmittance ≥90%, high clarity, no turbidity, no yellowing, solving the problem of traditional foaming materials’ opacity and poor clarity.
2. Transparent Stability: No yellowing, no turbidity after long-term use or exposure to light, maintaining high transparency, ensuring visual inspection accuracy.
3. Transparency & Performance Balance: While maintaining high transparency and clarity, it retains good elasticity and structural stability, no brittle fracture, balancing transparency and usability.
4. Compatibility with Transparent Products: Compatible with HONG YE SILICONE’s high-precision mold silicone and rapid prototyping silicone, forming a complete transparent solution, enabling one-stop procurement.
5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to fill precision molds, no professional transparent 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 transparency and clarity).
2. Mix and stir thoroughly for 2-3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure transparency uniformity and dense closed-cell structure).
3. Pour the mixture into transparent component mold (paired with high-precision mold silicone), foam and cure at room temperature or by heating.
4. After full curing, demold carefully, the product is transparent and clear, light transmittance ≥90%, ready for use in transparent and visual inspection scenarios.
Application Scenarios
Focus on transparent scenarios: Transparent electronic components (paired with Electronic Potting Compound), precision instrument transparent parts (paired with high-precision mold silicone), visual inspection robot components (paired with robot silicone), transparent packaging auxiliary parts (paired with Liquid Tank Silicone), and rapid prototyping of transparent parts (paired with rapid prototyping silicone). It helps transparent buyers ensure visual inspection accuracy and product appearance.
Certifications and Compliance
Passed SGS eco-toxicity certification, RoHS compliant, SGS transparency certification, excellent transparency and high clarity, meeting the transparent procurement requirements of B2B buyers in electronic, instrument and visual inspection industries, facilitating export to global markets.
Customization Options
Customizable light transmittance (≥95% for high-demand scenarios), clarity, foaming ratio and hardness, adapting to different transparent requirements, helping buyers optimize product transparency and visual effect.
Production Process
Transparent-oriented production process: High-purity transparent Silicone raw materials → formula optimization (ensure transparency and clarity) → precision mixing → transparency test → standardized curing → clarity inspection → packaging. Strict transparency control ensures product high-clarity performance.
