CCS Tyre Pneumatic Rubber Fender High Air Tightness Float Rubber Buffer
What’s Pneumatic Rubber Bumper?
Pneumatic rubber fender was first produced in 1958 by Yokohama Company of Japan, so it is also called Yokohama pneumatic fender.

Pneumatic rubber fender is an upgraded product of boat fender widely used worldwide, which is filled with high pressure air to withstand berthing impacts. Compared with normal elastic rubber fenders (such as waste tires, solid rubber fenders, etc.), it has high guaranteed energy absorption, low surface impact, combining high abrasion resistance with low friction and quick installation. Since its application, pneumatic rubber fender has been used as a buffer due to its high performance, and it has been widely used in ship-to-ship operation and ship-to-jetty operation.
What’s the Structure of Pneumatic Rubber Bumper?
Float rubber fender is made from inner rubber, synthetic-tyre-cord layer for reinforcement, outer rubber, flange opening and other metal parts.
The inner rubber is made from natural rubber with rubber content higher than 53%, which ensures the air retention of the pneumatic fender, and it can be used for a long time without obvious pressure relief. It is available in thickness from 2 to 4mm, which is determined according to the requirements of pneumatic rubber fenders of different specifications.
The synthetic-tyre-cord layer for reinforcement is gumming, and it features thick warps, competitive density and high strength. It is bonded with the inner and outer rubber after gumming, and then the three layers are bonded together after being vulcanized at high temperature. Therefore, the cord layer has high strength, abrasion and impact resistance, great thermostability, good adhesion with rubber, aging resistance and easy processing.
The outer rubber is mainly used to protect the reinforced layer and the inner rubber and further ensure the air retention of the float rubber fender.
What Are the Types of Pneumatic Rubber Bumper?
Type a: fender with with a heavy duty chain & tire net
Type b: sling-type fender
Type c: semi-submersible adjustable fender
Type d: customized net-type fender with special color
Special colors, such as black, white, red and grey(navy), can also be requested.
Net-type fenders can be customized with aircraft tires, net parts, conveyor belts and dock hoses.
