Comparison of Air Cylinder Floats by Material in Aquaculture (with Core Product Adaptation) 1. PET Air Cylinder Floats: Cost-Effective "Deep-Sea Applicable Type" (Recommended 80CM×10CM Size, Blue/Red Colors) Core Advantages: As an improved new-type float, PET has a stable molecular structure, with pressure resistance (0.3-0.5MPa water pressure) and anti-aging performance far exceeding other materials. In deep-sea oyster aquaculture, when used with 316 Stainless Steel Oyster Bag Shark Clip to fix HDPE Oyster Grow Bag, it can resist high-wave impact and deep-sea water pressure, preventing mesh bags from being dragged and sunk. Its bright blue and red colors provide a sea surface recognition distance of over 50 meters, making it easy for farmers to quickly locate the floats and reduce the loss risk of HDPE Oyster Mesh Bag and floats. Additionally, PET releases no harmful substances, complying with the EU No. 10/2011 environmental standards for aquaculture, which is suitable for export-…
