Which water cup is more durable, PPSU or Tritan?
When comparing the durability of water cups made of PPSU and Tritan, we need to analyze from multiple angles, including heat resistance, chemical resistance, impact resistance, and long-term stability. The following is a detailed comparison of the durability of water cups made of these two materials:

Heat resistance

PPSU is known for its excellent heat resistance and can withstand temperatures up to 180°C, making it suitable for high-temperature sterilization and microwave heating. In contrast, Tritan has a temperature resistance range of -40°C to 109°C. Although it can also withstand high temperatures, it may deform slightly under long-term high temperature environments

Chemical resistance
PPSU has good resistance to many chemicals, including acids, alkalis, alcohols, and some organic solvents. It is not attacked by common cleaners and disinfectants, making it ideal for containers and utensils, especially for applications that require frequent cleaning and disinfection. Tritan also has excellent resistance to a variety of chemicals, including acids, alkalis, alcohols, and some organic solvents, and is not attacked by common cleaners

Impact resistance
PPSU maintains its strength properties even at high temperatures. This makes the PPSU cups resistant to impact and deformation, and have a long service life. Tritan cups have good durability, are not easy to wear and impact, and can withstand long-term use.

Long-term stability
PPSU cups are generally more durable than Tritan cups, and can maintain stable physical properties for a long time, and are not easy to age or deteriorate. Although Tritan cups perform well in daily use, they may be slightly deformed in long-term high temperature environments.

Transparency and visual effects
Tritan has excellent transparency and visual effects, which is very suitable for applications that need to display content or require high transparency. PPSU is usually light yellow in color, has low transparency, and is relatively expensive.

Summary
Taking into account heat resistance, chemical resistance, impact resistance and long-term stability, PPSU cups have more advantages in durability, especially in situations where high-temperature disinfection or frequent microwave heating is required. Tritan cups perform better in transparency and visual effects, and also show good durability in daily use. Therefore, the choice of PPSU or Tritan cups should be determined according to specific usage needs and environment. For professional and demanding environments, especially those that require high heat resistance and chemical stability, PPSU is a superior choice. For ordinary families and daily use, or consumers who pursue visual effects and transparency, Tritan may be more suitable.
