THE ONLY ONE SUPPLIER IN ASIA

WHAT IS A BEAD

It is an essential part of all tires nowadays, whether open tires, tubeless tires or foldable tires, etc. The function lies in the fixation between the tire and the rim. The quality of the bead ring material also directly affects performance and safety. As the only one bead rings supplier in Asia, Mortop has been cooperating with the U.S. Du Pont for a long time in the past ten years to obtain certified defense material grade Aramid. It is a bulk material commonly used for high-quality bicycle tires and has excellent strength and toughness. Performance, under 115psi air pressure, it can withstand a thousand kilograms of pressure. The excellent toughness and low elongation are clearly reflected in performance and safety.

 

ARAMID

It is a new type of high-tech synthetic fiber with super high strength, acid and alkali resistance, light weight and high temperature resistance. Its strength is 5-6 times that of steel wire, and its modulus is 2 to 3 times that of steel wire or glass fiber. It is twice that of steel wire, and its weight is only about 1/5 of steel wire. It does not decompose or melt at a temperature of 560 degrees.High-grade aramid, commonly used in cables, body armor, missiles, etc., is a non-civilian material, showing its strength and ductility.In addition, it has good insulation and anti-aging properties, and has a long life cycle. The discovery of aramid is considered to be a very important historical process in the material industry.

Under 115psi

For the high pressure of bicycle tires, In high-grade brand, about 99% beads of all were made of Aramid. Due to the high strength, they can still be completely fixed on the rim under any rotation and friction, and the elongation is low and can be completely folding. After the folding is opened, the elasticity can still be maintained without deformation, the bead ring for tubeless must be made of Aramid material.

UP 115psi

In order to meet the increasing demand of users who use high-pressure tires, we began to plan and implement carbon fiber bead. After research and testing, a new carbon fiber bead material will be launched soon. In addition to lower ductility, lighter weight, and higher strength, we think it will be the most suitable bead material for high pressure tires. If you have any interest or questions, welcome to inquiry, please continue to pay attention to us to get the latest news in the near future.
