PP and PPSU vs PPSU is safer.
PPSU has higher temperature resistance. It can withstand temperatures up to 180 degrees Celsius while PP can only withstand about 100 degrees Celsius. This means that in products made with PPSU, such as milk bottles and food containers, food can be heated more safely without releasing harmful substances.
PPSU is more resistant to chemicals. It can withstand a wider variety of chemicals, such as acids, alkalis and organic solvents, whereas PP is relatively fragile. This makes PPSU suitable for use in many industries, such as medical equipment and laboratory supply manufacturing, where a variety of chemicals are often used for cleaning and sterilization.
PPSU has better impact resistance. It is better able to withstand external impacts and avoid product breakage and deformation. This means that products made with PPSU are more durable and less likely to cause injury in an accident.
Difference between ppsu material pp material
1. From the physical properties, PPSU material has higher heat resistance and chemical resistance. It can be used for a long time at high temperatures and can withstand higher working temperatures and impact pressure. The PP material has lower heat resistance and tends to deform easily or lose its original performance at high temperatures.
2, from the aspect of transparency, PPSU material has better transparency and surface quality. It has a smooth surface, no pores or texture, showing elegant brightness. While PP material has poorer transparency, and the surface may have bubbles or uneven texture, resulting in a less beautiful appearance.
3, PPSU material also has excellent electrical properties and dimensional stability. It has excellent insulating properties and can be used to make electronic equipment and electrical devices. At the same time, PPSU material has high dimensional stability, not easily affected by changes in ambient temperature and humidity, suitable for areas requiring high precision dimensions.
