Yokohama Rubber Fender Structure
Pneumatic fender consists of outer rubber layer, synthetic-tire-cord layer, and inner rubber layer. The outer rubber layer is made of special compounds that are strong with high tensile strength and tear strength to better protect the fender from the damage of severe weather conditions and hard usage. The synthetic-tire-cord layer is a composite tire cord with cross shadow lines, which is designed to distribute stress evenly. While the inner rubber layer is specially designed to seal the internal air and prevent any leakage.
