Choosing the Right Plastic Material for a Car Phone Holder

Updated: Jul 17, 2023



When choosing a suitable plastic material for making a car phone holder, several factors need to be considered. Here are some suggestions to help you make a decision:


Durability: The plastic material should be able to withstand the pressures and stresses typically encountered in a car environment, such as vibrations and temperature changes.


Heat resistance: Since cars can get hot, especially under direct sunlight, the plastic material should have good heat resistance to prevent deformation or melting.


Impact resistance: The phone holder should be able to withstand accidental impacts or drops without easily breaking. Choose a material with high impact resistance.


Stability: The plastic material should have good dimensional stability, meaning it maintains its shape without excessive shrinking or expanding due to temperature or humidity changes.


Chemical resistance: Considering potential exposure to common chemicals found in cars, such as cleaners or gasoline, the plastic material should have the ability to resist chemical corrosion to avoid degradation or discoloration.


Grip and friction: The surface properties of the plastic material should be appropriate to provide a secure grip on the phone, preventing it from sliding or slipping during car rides. Choose a material with a good friction coefficient.


Ease of manufacturing: Consider the ease of molding and processing the plastic material. Some plastics may be more suitable for injection molding.

Cost: Evaluate the cost-effectiveness of the plastic material, including raw material costs, manufacturing processes, and mold expenses.


Common plastic materials used for car phone holders include:


ABS (Acrylonitrile Butadiene Styrene): It offers a good balance of durability, heat resistance, and impact resistance. It is widely used in automotive applications.


PP (Polypropylene): It has excellent chemical resistance and is relatively inexpensive. It is commonly used in automotive interiors and can be a suitable choice for phone holders.


PC (Polycarbonate): It provides high impact resistance and heat resistance. It is transparent and can offer an aesthetically pleasing design for the phone holder.


POM (Polyoxymethylene): It is a strong and durable material that can provide excellent support and stability. Its high wear resistance enables it to withstand prolonged usage without significant abrasion or scratches. Additionally, POM has a low coefficient of friction, offering smooth sliding characteristics that make placing and removing the phone effortless.


PA(Nylon): It is a strong and durable material that exhibits excellent structural strength, enabling it to withstand high loads and impacts. It also demonstrates good wear resistance, effectively resisting friction and abrasion, it also has excellent chemical resistance, making it highly resistant to chemical corrosion and less susceptible to damage from common chemicals.


When choosing plastic materials, you can consider the characteristics of each material based on the needs of the automotive phone holder, and then select the appropriate material.
