🥊 Competitor 1: PP (Polypropylene)

• ✅ Features: Inexpensive, acidic and alkali resistant.
• ❌ Weaknesses: Poor elasticity, non-wear-resistant, and highly vulnerable to heat. Once it exceeds 80°C, its stiffness drops sharply, making it extremely prone to deformation.
• 📌 Conclusion: Suitable for rugged scenarios like room-temperature dust removal and road sweepers, but "gives up instantly" at high temperatures.

🥊 Competitor 2: Nylon (PA6 / PA66)

• ✅ Features: Excellent resilience, high wear resistance, and good toughness.
• ❌ Weaknesses: Strong water absorption. In long-term high-temperature and high-humidity environments, Nylon easily absorbs moisture which leads to performance fluctuations. Furthermore, its corrosion resistance to strong acids and alkalis is inferior to PET.
• 📌 Conclusion: Good comprehensive performance, but struggles slightly in extreme high-temp and highly corrosive environments.

👑 Competitor 3: PET (Polyester)

✅ Features: Combines the strengths of many.

• Heat Resistance: Continuous operating temperature up to 120°C, maintaining stable physical properties under high heat.
• Corrosion Resistance: Excellent resistance to acids, alkalis, alcohols, gasoline, etc.
• Low Moisture Absorption: Extremely low water absorption with excellent dimensional stability; will not soften in damp environments.

💡 Summary Guide

If you seek cost-effectiveness for mild conditions, choose PP;
If you value resilience and toughness, choose Nylon;
But if you are facing the severe challenges of high temperatures and strong acids/alkalis, PET High-Temp Bristles are absolutely your best partner!
