What Are Automotive Parts Applications?

SUMIKASUPER LCP has many excellent features and is a material that can help to resolve problems related to automobile development such as:

1. Vehicle weight reduction.
2. Reduction of harmful gases and CO2 emissions.
3. Better fuel efficiency.
4. Introduction of new parts through electrification.

Specific Benefits of Using SUMIKASUPER LCP for Automotive Parts

• Thanks to its high flowability and excellent mechanical properties, it is possible to reduce the number of parts by integrating multiple parts, make parts more compact, and reducing the weight through thinning.
• It has good heat resistance (300°C or higher), allowing it to replace metal parts exposed to high temperature environments such as engines and lights.
• It also has good dimensional stability (low expansion and shrinkage) in the extremely low to high temperature range required for automobiles, so it is possible to minimize product deformation caused by temperature changes. There is almost no loss of physical properties due to heat shock or the wetting and drying cycle.
• Since it has extremely low water absorption and minimal dimensional changes due to humidity, it is easy to design parts.
• It has excellent chemical resistance and can be used even in environments where it comes in contact with gasoline, engine oil, ATF, and LLC.
• It has excellent vibration damping properties, making it ideal for parts around engines, motors, and transmissions where resonance is an issue, housing components that require sound insulation such as gearboxes, and exterior panel components that insulate against rain and outside sound.
• It has been widely used with connectors and coil bobbins for electrical and electronic equipment, and can also be applied to in-vehicle electronic equipment components such as EV motor parts and PCUs.
