How does the glass transition temperature of PVC affect outdoor seating flexibility?
The glass transition temperature (Tg) of PVC plays a critical role in determining the flexibility and durability of outdoor seating. PVC, a widely used polymer, transitions from a rigid, glassy state to a softer, rubbery state as temperatures rise above its Tg (typically around 80°C for rigid PVC). In outdoor environments, temperature fluctuations can cause PVC seating to become brittle in cold weather or overly soft in heat, affecting comfort and longevity. Understanding Tg helps manufacturers design seating with additives or plasticizers to adjust flexibility, ensuring reliable performance across seasons. Proper formulation ensures PVC seating remains resilient, weather-resistant, and comfortable for users year-round.
