Sinmark PP (Polypropylene) material has the following characteristics:

1. Lightweight: It has a low density, making it lighter than many other plastics.

2. High Strength: It exhibits good tensile and flexural strength.

3. Chemical Resistance: It has excellent resistance to a wide range of chemicals, including acids, alkalis, and organic solvents.

4. Heat Resistance: It has a high melting point (around 160-170°C), maintaining stable physical properties at high temperatures.

5. Cold Resistance: It retains some toughness at low temperatures, though it may become brittle at extremely low temperatures.

6. Insulating Properties: It has excellent electrical insulating properties, making it suitable for electrical and electronic applications.

7. Transparency: Its transparency can be altered by adjusting processing conditions and additives, typically being translucent or opaque.

8. Fatigue Resistance: It shows good fatigue resistance under repeated bending and stretching.

9. Recyclability: It is environmentally friendly and can be recycled multiple times. PP material is widely used in packaging, automotive, household appliances, medical devices, and textiles.
