Automotive Ceramic Catalyst Thermal Insulation Cotton Gas System Ceramic Catalyst Thermal Insulation Material Heat insulation protection: prevent high-temperature exhaust gas from thermal damage to peripheral parts and prolong their service life. For example, reduce the impact of high temperatures on nearby sensors, wiring harnesses, etc., reducing their risk of aging and failure. Maintain the working temperature of the catalyst: it helps to keep the ceramic catalyst working within the appropriate temperature range and improve its catalytic efficiency. Ensure that under different working conditions, the catalyst can effectively convert harmful gases into harmless substances. To cope with humid and harsh working environments，Our products are made of sealed materials and stamping technology. We use pure copper wire for greatly improved performance, and the wire is made of anti-aging material for durability., Manufacturer: DGOINGPI
