The durability of plastic parts depends on a variety of factors, including the type of plastic, manufacturing process, additives, use environment, and maintenance. Here are some key factors that affect the durability of plastic parts:

Plastic type:
Thermoplastics (such as PE, PP, PS, ABS, PC, etc.): These plastics can be reshaped at high temperatures, have good impact resistance and recyclability, but may become soft or deformed after long-term exposure to high temperatures.
Thermosetting plastics (such as PF, UF, EP, BMI, etc.): These plastics cannot be reshaped after curing and usually have better heat and chemical resistance, so their durability is usually higher.

Additives:
UV stabilizers can improve the durability of plastics when used outdoors.
Antioxidants and light stabilizers can prevent plastics from aging.
Fillers and reinforcements (such as glass fiber, carbon fiber) can increase the strength and heat resistance of plastics.

Manufacturing process:
Different molding processes such as injection molding, extrusion, and blow molding will affect the density, strength, and durability of plastic parts.

Use environment:
Temperature: Plastics may become more brittle or soft in extreme temperatures.
Humidity: Some plastics may absorb water in humid environments, causing dimensional changes and performance degradation.
Chemicals: Plastics have different tolerances to chemicals, and some may degrade when exposed to oils, solvents, or other chemicals.
Sunlight: UV rays can cause plastics to age, fade in color, and lose strength.

Maintenance:
Regular cleaning and proper care can extend the life of plastic parts.
Avoid using abrasive cleaners or brushes to prevent scratches and wear.
In general, the durability of plastic parts can be very high, especially when the above factors are taken into account during design, and the appropriate materials and manufacturing processes are selected. For example, plastic parts in automotive interiors are often designed to have a long service life and can withstand years of daily use and environmental exposure. However, the durability of plastic parts can also be relatively low, especially in harsh environmental conditions or if the appropriate materials and additives are not used. Therefore, the design and manufacture of plastic parts need to be tailored to their intended application and environment.
