Title:
MULTILAYER TUBE APPLIED TO AIR BRAKES
Document Type and Number:
WIPO Patent Application WO/2021/045164
Kind Code:
A1
Abstract:
A multilayer tube applied to air brakes comprises the multilayer tube made of polyamide, particularly applied to the air brake system for automotive vehicles, and also features such layers with excellent elasticity, durability, abrasive resistance and resistance to high pressures; therefore this inner layer has properties that support the pressurized air of the air brake system that passes through the tube, avoiding ruptures to the tube and then assuring the operation and durability of the tube in question, and, consequently, of the air brake system to which the tube is applied.
