High - temperature tapes used in the automotive manufacturing field need to possess the following environmental - friendly properties:
They should comply with relevant international and domestic environmental standards such as the EU RoHS Directive, strictly restricting the use of harmful substances like lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls and their ethers.
During the production, use, and the vehicle's service life, they should not release volatile organic compounds (VOCs) such as formaldehyde, benzene, toluene, and xylene, preventing pollution of the air inside the vehicle and safeguarding the health of the vehicle occupants.
After the vehicle is scrapped, the high - temperature tape should be able to decompose into harmless substances within a certain period under natural environmental conditions or specific treatment conditions, reducing the generation of solid waste and alleviating the pressure on the environment.
The tape material should be easy to recycle and reuse. It can be recycled together with other recyclable materials of the vehicle, re - entering the material recycling system to improve resource utilization.
Clean production technologies should be adopted during the production process to reduce the discharge of wastewater, waste gas, and solid waste, lower energy consumption, and minimize the negative impact on the ecological environment as much as possible.
During the production process, no or very few harmful by - products and waste should be generated, avoiding harm to the surrounding environment and ecological system.
It should have good compatibility with various materials used in automotive manufacturing, such as metals, plastics, rubbers, and glass. It will not react chemically with these materials, generating harmful substances or affecting the performance of the materials, ensuring the overall environmental - friendliness and safety of the vehicle.
During various automotive manufacturing processes such as painting, baking, and assembly, it will not cause adverse environmental impacts due to process conditions such as high temperature and chemical treatment. It will not release harmful gases or generate other pollutants.
After the completion of automotive production, when the tape is peeled off from the surface of the vehicle body or components, no adhesive residue will be left. This avoids the use of organic solvents for cleaning, reducing the pollution caused by the volatilization of organic solvents and facilitating subsequent cleaning and processing work.
