Natural Rubber FAQ
Q: What makes Natural Rubber superior to synthetic alternatives?
A: Natural Rubber offers exceptional elasticity, higher tensile strength, better fatigue resistance, and superior vibration damping properties compared to most synthetic rubbers. Its molecular structure provides natural resilience that's difficult to replicate synthetically, making it ideal for applications requiring repeated flexing or impact absorption.
Q: How does temperature affect Natural Rubber performance?
A: Natural Rubber maintains excellent flexibility at low temperatures (down to -60°C) and performs well up to 80°C. It has a lower glass transition temperature than most synthetic rubbers, meaning it stays flexible in cold conditions while offering good heat resistance for many applications. However, prolonged exposure above 80°C may cause gradual deterioration.
Q: What are the environmental benefits of choosing Natural Rubber?
A: Natural Rubber is a renewable resource harvested from rubber trees that continue to absorb CO2 throughout their productive life (20-30 years). It's biodegradable at the end of its lifecycle, unlike synthetic rubbers derived from petroleum. Sustainable rubber plantations also support biodiversity when properly managed.
