Certification standards
ISO 9001 is an international standard for quality management systems, while ISO/TS 16949 is a quality management system for the automotive sector. ASTM D2000 and SAE J200 are rubber material specification standards, while RoHS and REACH regulations govern hazardous materials in electronic and electrical equipment. Rubber radiator insulator pads may need to comply with these standards if certain chemicals are used in them. The use of hazardous materials in electronic and electrical equipment is restricted under the EU's RoHS directive.
Introduce
Rubber radiator insulator pads are special radiator parts that are mostly used in car radiators for electrical and thermal insulation. Rubber, which has great heat resistance and electrical insulating properties, is frequently used to make it. In conclusion, it serves a vital role in the vehicle's cooling system and has the advantages of heat resistance, vibration resistance, and simplicity of installation. They improve the overall efficiency and performance of the cooling system while preserving the radiator's safe operation.
Advantage
Rubber radiator insulator pads offer several benefits, including electrical insulation, thermal protection, heat resistance, vibration isolation, and chemical resistance. They effectively separate current conduction between the radiator and other electrical components, preventing shorts, shocks, and malfunctions. They prevent heat loss and enhance the radiator's functionality. Rubber is resistant to high temperatures, ensuring its stability and longevity in hot weather conditions. They also reduce vibration transmission during driving, making driving more comfortable. Additionally, their chemical resistance prevents damage to lubricants, coolants, and other chemicals. They are easy to install into radiators and other components, enhancing manufacturing efficiency.
