Automobile plastics is a major development trend of international automobile industry today. The current market demand for cars has shifted to lighter sport-utility vehicles, minivans and other light vehicles, which will lead to more lightweight developments. The demand for plastic is also high.

1. Excellent weather resistance, ensuring the use of non-discolored, non-aging cracks (including heat-resistant oxygen aging and light aging) for a long time;

2. Excellent chemical resistance to resist the erosion of oil and Japanese products;

3. It is easy to form, and it should have sufficient liquidity for injection molding materials to ensure the forming of complex parts and improve production efficiency;

Economy, demand material has high cost performance.

Material requirements for external trim

1. Weatherability: the materials for non-coating or electroplating should be used for waiting materials such as AES, ASA (AAS), PC/PBT (PET), etc.

2. Heat resistance: due to low ambient temperature, the standard heat resistance level can meet the requirements;

3. Low temperature resistance: it requires the material to have certain low temperature resistance, and prevent the cracking of parts in cold winter environment;

4. Chemical resistance: prevent the erosion of oil and acid rain;

5. Scratch resistance: the material has a certain surface hardness and low friction coefficient to prevent scratches.

Material requirements for interior trim parts

1. Heat resistance: because of the prolonged exposure to light in summer, the temperature in the carriage is relatively high, which requires high heat resistance of the materials.

2. Aging resistance: including heat and oxygen aging and light aging to prevent the aging of components from ageing and deterioration;

3. Smell: in order to drive the health of people, materials should ensure low volatility and low odor;

4. Matte light: to ensure driving safety, choose matte or matte skin lines;

5. Scratch resistance: the material has a certain surface hardness and a low friction coefficient to prevent scratches.
