Polypropylene, commonly called PP, is a versatile plastic material businesses use widely in many industries. One of its unique properties is that it has the lowest density among all types of plastics. This means it is incredibly lightweight, making it an ideal material for applications where weight is a concern, such as in the automotive and aerospace industries. In addition, PP is also highly resistant to chemicals, moisture, and impact, making it a popular choice for packaging, food containers, and even medical devices. So, if you're looking for a lightweight and durable plastic material that can withstand harsh conditions, then PP is definitely worth considering!
