Understanding HDPE
High-Density Polyethylene (HDPE) is a thermoplastic polymer made from petroleum. It is characterized by its density, with long chains of hydrocarbons leading to fewer branching structures compared to other types of polyethylene. This structure contributes to its rigidity and strength. HDPE is known for several key properties:
- High Strength-to-Weight Ratio: HDPE sheets are lightweight yet highly durable, making them suitable for both structural and decorative applications.
- Chemical Resistance: HDPE is resistant to many chemicals, including acids, alkalis, and alcohols, enabling it to be used in various industrial environments without degradation.
- UV Resistance: When UV-stabilized, HDPE sheets can withstand prolonged exposure to sunlight without significant fading or breaking down.
- Low Moisture Absorption: HDPE has minimal water absorption, making it suitable for wet environments and outdoor applications.
