The primary cause of the increased balloon friction on surfaces is tightening the stent. If the stent has to be taken off during the transportation to the location site it could cause severe complications in the process. To avoid this, the friction on the surface can be controlled by using different balloon materials.
Every balloon material has a different coefficient that influences the friction on the surface that the balloon experiences. You can browse https://www.pobamedical.com/capabilities/medical-balloon-testing to get the best medical balloon testing services.

Materials with low coefficients include PET nylon, nylon, and high-strength PEBA. Other high coefficient materials include low durometer PEBA and urethane with a low durometer.
If the ball has an extremely low value for friction coefficient, a higher compressive force is needed to attain that same static. The coefficient of friction for low-durometer urethane can be 3.5 times greater than PET.
It also improves durability by an increase of 3.5 at identical pressure. Multi-layer structures are suggested for high breaking loads and high friction on the surface. The layer that is used in this model is of high durometer PET PEBA, nylon, or PEBA. Then, an outer one is PEBA which is a low durometer, or urethane with a low durometer.
When blow-molded, the skin’s wall thickness will be decreased by 0.0003-0.0004 inches. It is not so many changes the profile but improves the friction on the surface. Additional, more complex techniques for texture are required to increase friction on the surface.
