When choosing PE tarpaulin, consider the following aspects:
Waterproof Performance
Water Permeability Test: After repeatedly rubbing the PE tarpaulin, soak it in water for one minute and observe the water permeability. High-quality PE tarpaulin should not absorb water or absorb water but not permeate; this is an important indicator of its waterproof performance.
Tear Resistance and Abrasion Resistance
Tear Resistance Test: The tear resistance of PE tarpaulin can be evaluated through a simple tensile test. Select a small piece of tarpaulin and try to pull it with appropriate force, observing whether it breaks easily. Tarpaulin that can withstand a certain tensile force (e.g., 200N) without breaking is of higher quality.
Abrasion Resistance Test: Place the PE tarpaulin on a cement floor, add a suitable weight, and rub it back and forth multiple times (e.g., 20 times). Check if the tarpaulin surface is pilling; tarpaulin with less pilling and a well-preserved overall structure has better abrasion resistance.
Material Safety
Non-toxic Material: High-quality PE tarpaulin should be made of non-toxic high-density polyethylene, odorless, and harmless to the human body. When purchasing tarpaulins, be wary of those produced by small workshops or processing plants that may contain harmful substances due to improper ingredient ratios.
Manufacturer and Brand Reputation
Choose reputable manufacturers: When purchasing, try to choose manufacturers or brands with formal production lines, production qualifications, and a good reputation. This can better guarantee the quality and safety of the tarpaulin.
