Physical and mechanical properties: Automotive leather needs to have good physical and mechanical properties, including tensile strength, tear strength, wear resistance, bending fatigue resistance, etc. These properties ensure that automotive leather can withstand various mechanical stresses and maintain its shape and function over long-term use.
Chemical properties: The chemical properties of automotive leather are also very important, including chemical corrosion resistance, oil resistance, solvent resistance, etc. These properties ensure that automotive leather remains stable when in contact with various chemicals, without deformation or damage.
Combustion performance: Automotive leather needs to have good combustion performance, including flame retardancy and smoke density. These features ensure that in the event of a fire, automotive leather can slow down the spread of fire and protect passenger safety.
Environmental requirements: The production and use of automotive leather must comply with environmental requirements, including low VOC emissions, non-toxic and harmless, recyclability, etc. These requirements ensure that automotive leather has minimal environmental impact during use and disposal.
Appearance and feel: The appearance and feel of automotive leather are also important considerations, including color uniformity, surface smoothness, and comfortable feel. These characteristics directly affect the visual and tactile experience of the in car environment.
Safety performance: Automotive leather needs to have certain safety performance, including tear resistance, puncture resistance, etc. These features ensure that automotive leather can provide some protection in case of unexpected situations.
Other requirements: In addition, automotive leather also needs to meet specific physical and chemical performance indicators, such as coating adhesion strength, atomization value, odor level, pH value, prohibited azo dye content, free formaldehyde content, etc. These indicators ensure the safety of automotive leather for both humans and the environment during use.
