2. Efficient Noise Reduction: Reduces noise transmission by ≥30dB, blocks noise spread, creates a quiet working environment, improving work comfort and equipment stability.
3. Sound-Absorbing & Durability Balance: While maintaining excellent sound absorption performance, it retains good wear resistance and elasticity, no deformation, no performance degradation after long-term use, service life is 3-4 times that of traditional sound-absorbing foaming materials.
4. Noise-Reduction Compatibility: Compatible with HONG YE SILICONE’s industrial Mold Silicone rubber and high-temperature insulation silicone, forming a complete noise-reduction solution, enabling one-stop procurement for noise-reduction buyers. 5. Easy Operation: 1:1 simple mixing ratio, good flowability, easy to process into sound-absorbing components, no professional sound-absorbing 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 sound-absorbing performance).
2. Mix and stir thoroughly for 3 minutes until homogeneous, vacuum degas to remove air bubbles (ensure sound-absorbing uniformity and open-cell structure).
3. Pour the mixture into noise-reduction component mold (paired with industrial mold silicone rubber), foam and cure at room temperature or by heating.
4. After full curing, the product has excellent sound absorption and noise reduction, can be directly used in noise-reduction scenarios, blocking noise transmission.
Application Scenarios
