Multi-layer structure design:Automobile air conditioning hoses usually adopt a multi-layer structure. For example, a five-layer automobile air conditioning hose has an inner rubber layer, a nylon shielding layer, a middle rubber layer, a polyester fiber reinforcement layer, and an outer rubber layer from the inside to the outside. This structural design can prevent seepage layer by layer and effectively reduce the permeability of the refrigerant.

• Inner rubber layer and middle rubber layer: Usually chloroprene rubber (CR) is used as the main material, which has excellent anti-permeation performance and shows low permeability to refrigerant R1234yf. At the same time, it has small compression permanent deformation and is resistant to compressor oil (such as PAG and POE). The inner rubber material has little precipitation of substances to avoid contamination of the air conditioning system.
• Nylon shielding layer: Made of nylon 6, it has good toughness, shock resistance and heat resistance, and can further reduce the penetration of refrigerant.
• Polyester fiber reinforcement layer: provides sufficient strength to withstand working pressure, has high modulus and good shape retention, prevents the pipeline from hollowing and collapsing, and ensures the smooth flow of the pipeline.
• Cover: Usually chlorobutyl rubber (IIR) or ethylene propylene diene monomer rubber (EPDM) is used, which has good weather resistance, heat resistance, moisture resistance and low air permeability. It also has high damping characteristics for low-frequency vibrations and can reduce vibration and noise.
