Relationship between different materials and strength of plastic handle
There is a direct relationship between the material and strength of plastic handles. Plastic handles made of different materials have different physical and chemical characteristics, which affect their strength and durability. The following is a detailed description of several common plastic handle materials and their strength characteristics:
PE
PP
PC
PS
PE
Polyethylene (PE): Polyethylene has good wear resistance, corrosion resistance and aging resistance, but because of its strong flexibility, it is usually used to make low-load handles. Polyethylene handles are suitable for household daily necessities with light load, such as clothes hangers and plastic baskets.
PP
Polypropylene (PP): Polypropylene has higher strength and rigidity, and is suitable for manufacturing high-load handles. It also has good high-temperature resistance, and is suitable for occasions where it needs to be used in high-temperature environment. Polypropylene handles perform well in handling medium weights.
PC
Polycarbonate (PC): Polycarbonate has excellent impact resistance and heat resistance, and is suitable for high-load and high-strength handles. It also has good transparency and weatherability, and is suitable for long-term use in outdoor environment.
PS
Polystyrene (PS): Polystyrene has good wear resistance and impact resistance, but it is usually used for low-load and low-strength handles because of its easy deformation and breakage. It is suitable for household daily necessities with light loa
What methods of improving the strength of plastic handle?

-
1. Selection of suitable materials and reinforced structural design: high-strength materials such as polypropylene, polyethylene or engineering plastics such as ABS are common choices. In addition, adding fillers such as glass fiber and carbon fiber can significantly improve the rigidity and strength of plastics. Complex geometric structures such as "X" shape or "T" shape can be used in design to increase the stress area and disperse the external pressure. The introduction of advanced manufacturing technology, such as injection molding, can ensure that each part of the plastic handle reaches the ideal density and hardness and enhance the overall strength. Hot forming and cooling treatment can also reduce the internal stress and improve the stability of the handle;
2. Considering environmental factors and long-term durability: adding anti-ultraviolet additives can prolong the service life of the handle, while anti-slip design can improve the grip and reduce the risk of slipping.
