The most common coating for pistons is graphite or molybdenum disulfide (MoS2). These coatings are applied to reduce friction, wear, and enhance the piston's performance under harsh operating conditions. Graphite, being a solid lubricant, offers good lubricity and high-temperature resistance, which is vital for engine components that experience significant heat and pressure. Molybdenum disulfide, on the other hand, is renowned for its exceptional strength and ability to form a solid lubricating layer that can withstand extreme pressures and temperatures, further protecting the piston and improving engine efficiency. Automakers and engine builders often choose these coatings for their balance of performance, durability, and cost-effectiveness, making them a standard in the industry for enhancing engine life and operational efficiency.

Polyethylene (PE) and Polypropylene (PP) are both thermoplastic polymers used widely in various applications. The key difference lies in their chemical structure; PE is composed of a simple chain of carbon atoms, while PP includes a carbon chain with a pendant methyl group, making it slightly stiffer and more resistant to chemicals and temperatures. Polyethylene is known for its flexibility, making it ideal for products like plastic bags and bottles, whereas polypropylene, with its higher melting point, is used for items that require more rigidity, such as food containers and automotive parts. Additionally, PP is slightly harder and more heat resistant, whereas PE offers better ductility and impact strength. Choosing between them depends on the specific requirements of the application, including durability, flexibility, and resistance properties.
