D3300*4500L High Pressure 50kpa 80kpa Pneumatic Rubber Fenders
The basic body construction of a pneumatic rubber fender consists of an outer layer made of rubber, cord layers and inner rubber layer vulcanised together. End flanges are available at both ends for air charging purposes. The outer rubber layer is made of strong rubber material to withstand external forces and protect the other layers from abrasion as well as hard usage on bad weather conditions. MAX cord layers are innovatively designed at ideal angles to evenly distribute the stress acting upon the fender. Integrative twine technology and polyamide fiber with high tensile stress are applied to provide strength and hold the internal pressure during usage. This helps distribute the stress uniformly, maintaining the energy absorption and increasing its efficiency. The inner layer is tasked to seal the air inside, minimising the air leakage using a material with airtight qualities.
The basic body construction of Floating pneumatic rubber fender consists of outer rubber layers, synthetic-tire-cord layers and inner layers. In addition, we can also bring tire sheath, net bag sheath, chain sheath, etc. Please take the picture for reference.
All of these layers are vulcanized together ,and then compress air inside to enable the fender to float on the sea surface.
