This compaound has sufficient tensile and tear strength to withstand any weather condition and hard uasage.   2.2 Inner layers   The inner layers seals the pressurized air inside the fenders.   2.3 Synthetic-tire-cord layers for reinforcement   2.3.1 Please see below picture to find the difference in arrangement of tyre-cord and canvas fabric.   2.3.2 Example of difference in the physical property    The synthetic-tire-core arrangement has strength in one direction only while the canvas-fabric arrangement strength is both two directions. Table 1 and Table 2 provide an example of difference in physical properities between these two diffetent materials.   Table 1- Synthetic tyre core of rubber pontoon fender

  2.4  Beading Ring   A steel ring is placed at one end(or both two ends) of the fenderand holds the end of core layers.   2.5 Flange      A steel flange is mounted on the fender, to which an air valve or safety valve can be adapted.   2.6 Safety Valves    Feders of diameter 2500mm and larger shall be enquipped with a safety valve of releasing excess internal pressure whrn fenders are over compressed accidentally. Fender which are smaller than 2500mm in diameter can be also enquipped a safety valve if required by customer.   2.7 Metal acessories   All relevant metal Accessories including shackles, towing rings, swivels and Chain net are made of stainless steel or hot dipped galvanized which are resistant for sea water corrosion.     2.8 Chain and tire nets   The purpose of chain of tire net is to protect the fender body from damage by sharp objects or protrusions such as rough faced quay walls, to distribute sheer forces along the length of th chain net to provent the fender body when it has to absorb them.
