In terms of the choice of plastic material, what type of plastic is used in this gel pen to ensure that it is both light and durable?

In terms of the choice of plastic material, this gel pen may use engineering plastics such as ABS, AS, PP or POM to ensure that it is both light and durable. ABS plastic is an extremely common thermoplastic plastic that is widely used in electronic products, automotive parts, office supplies and other fields due to its good comprehensive properties. ABS plastic combines the chemical corrosion resistance of acrylonitrile, the elasticity of butadiene and the gloss and processability of styrene, allowing it to provide sufficient strength and toughness while maintaining a light weight. In the manufacture of gel pens, ABS plastic can ensure that the pen barrel is not easily damaged during frequent use and accidental drops, and its good processability also makes it easy for manufacturers to produce pen barrels in various shapes and colors.
Although AS plastic is similar to ABS in some properties, AS generally has higher transparency and better heat resistance, which makes it an ideal choice for manufacturing transparent or translucent plastic products. In the field of gel pens, AS plastic can be used to manufacture pen barrels with unique visual effects while maintaining the durability and stability of the product. However, since the hardness and wear resistance of AS plastic may be slightly inferior to ABS, it needs to be weighed according to specific needs in practical applications.
PP plastic is known for its light weight, high strength, wear resistance and good chemical stability. In gel pen manufacturing, PP plastic can be used to make pen barrels, providing a comfortable grip and good durability. In addition, PP plastic is easy to process and recycle, meets environmental protection requirements, and is also one of the important factors that manufacturers consider when selecting materials.
POM plastic is known for its excellent mechanical properties, wear resistance and self-lubrication. In gel pens, POM plastic is often used to manufacture internal mechanical parts such as pressing mechanisms, refill holders, etc. to ensure that these parts maintain high precision and stability in long-term use. Although the cost of POM plastic is relatively high, its excellent performance makes it an ideal choice for manufacturing high-end gel pens.
