Why TPR Material Outperforms Silicone for Reusable Earplugs?

When it comes to choosing the best material for reusable earplugs the decision goes beyond comfort. The material impacts hygiene durability cost and whether workers keep them in place during long shifts. While silicone has long been used in hearing protection thermoplastic rubber TPR is proving to be the better choice for many industries.

Comparing Silicone vs. TPR: Key Factors

Here are two RONCO products previously made with silicone, now upgraded with TPR for improved performance.

1. HUSH™ Metal Detectable Silicone Earplugs (50-25CD)

1. NRR 25 dB
2. Curved flanges for sealing
3. Metal-detectable earplugs and cords for food industry safety
4. Bright blue color for visibility

TPR Advantages over Silicone:
In food processing or humid environments, TPR would offer stronger grip and longer-lasting comfort. With detectability embedded directly in TPR, the plug could stay softer and more flexible while still meeting industry standards.

2. HUSH™ Reusable Earplugs (50-23C)

1. NRR 25 dB
2. Curved flanges for effective noise seal
3. Bright citron color for visibility
4. Hygienic storage case

TPR Advantages over Silicone:

For long shifts and frequent re-insertion, TPR provides better durability and maintains comfort over time. It resists deformation and surface wear, making it more reliable in industrial environments.

Concluding Insight

TPR doesn’t just match silicone—it raises the bar. With superior grip, durability and hygiene, TPR material makes reusable earplugs more effective and more comfortable for workers. For companies looking to improve compliance and reduce replacement costs, TPR earplugs are the future of hearing protection.
