PE tarpaulin, also known as polyethylene tarpaulin, is a flexible material made by mixing high-density polyethylene (HDPE) or low-density polyethylene (LDPE) with UV stabilizers, anti-aging agents, etc., and then processing it through weaving or calendering. Its core characteristics include:
Waterproof: PE has a dense molecular structure and its surface can be coated, achieving 100% waterproof performance (hydrostatic pressure test ≥3000mm).
Lightweight and Durable: With a density of only 0.94-0.96g/cm³, it weighs 30%-50% less than traditional canvas, and its service life is typically 3-5 years (for regular outdoor use).
Low Cost: The raw material price is approximately 8-12 RMB/kg (2023 market price), and the finished product price is only half that of PVC tarpaulin.
