Tritan, ppsu, PP material, which one is best to do bento box?
Tritan is better than pp, and pp is better than ppsu.
(1) Maximum temperature resistance
PP can withstand up to 100°C, the glass transition temperature of Tritan's individual brands can reach 120°C, and PPSU can reach up to 137°C.
(2) Hardness
The hardness of PPSU and Tritan are comparable, and both are higher than PP.
(3) Security
The three have good chemical resistance, but PPSU is easy to precipitate bisphenol A after scratching, and Tritan has obvious advantages in chemical resistance. Both PP and Tritan can be used in contact with food.
(4) PPSU
PPSU has high transparency and high temperature resistance, but because BPA bisphenol A makes PC gradually withdraw from food container applications, it still has a wide range of applications in other industrial fields.
(5) PP
PP has relatively poor appearance transparency and relatively high safety. The heat resistance of PP is the lowest among the three materials, and the use temperature should not exceed 100 degrees.
From that, we can get tritan mateial is the best to do tableware to contact food.
