The common materials for plastic toolboxes include polyolefin plastics, engineering plastics, etc. Here are some specific introductions:
1. Polyolefin plastics
Polyethylene (PE)
    Characteristics: It has good corrosion resistance, wear resistance, and low temperature resistance, good chemical stability, and is insoluble in any organic solvents at room temperature. It is resistant to acid, alkali, and various salt corrosion. Among them, high-density polyethylene (HDPE) has better hardness, tensile strength, and creep resistance than low-density polyethylene, and also has good rigidity and toughness.
    Application scenarios: Suitable for making outdoor toolboxes, which can be used to extrude packaging films, ropes, woven bags, fishing nets, water pipes, etc. It can also be used for injection molding low-grade daily necessities and shells, such as plastic pallets, plastic buckets, plastic trash cans, etc.
Polypropylene (PP)
    Characteristics: It is a semi crystalline thermoplastic with excellent heat resistance, chemical corrosion resistance, and insulation properties. It has good strength, elasticity, and molding performance. Even if bent, it will not damage the object itself. It is immune to other chemical reagents except for being corroded by concentrated sulfuric acid and concentrated nitric acid.
    Application scenarios: commonly used for making indoor toolboxes, as well as for producing plastic toolboxes, plastic packaging boxes, etc.
2. Engineering plastics
Polycarbonate (PC)
    Characteristics: A high-strength and highly transparent engineering plastic with good thermal stability, high temperature resistance, UV corrosion resistance, wear resistance, and strong impact resistance.
    Application scenario: Suitable for making transparent or semi transparent toolboxes, commonly used in the manufacturing of toolboxes, able to adapt to complex working environments.
Acrylonitrile butadiene styrene copolymer (ABS)
    Characteristics: A thermoplastic polymer material with high strength, good toughness, and easy processing and shaping. It is resistant to oil corrosion, has good insulation performance, a smooth surface, is resistant to drops, and is not easily damaged or scratched.
    Application scenario: Suitable for making various toolboxes, widely used in the manufacturing of various toolboxes.
Polyamide (PA, commonly known as nylon)
    Characteristics: It is a type of engineering plastic that has the characteristics of easy processing and molding, good fatigue resistance, heat resistance, acid and alkali resistance, durability, good rigidity, high strength, and resistance to impact damage.
Application scenario: Suitable for making various toolboxes, it can protect tools from damage for a long time.
3. Other plastics
Ethylene vinyl acetate copolymer (EVA)
    Characteristics: Non toxic, odorless, low density, high strength, high stiffness, excellent hardness and heat resistance, printable, with high heat adhesion, low temperature resistance, biodegradability, free of heavy metals, resistant to water, salt and other corrosive elements, strong stability.
    Application scenario: Can be used to make toolkits, often used as lining or auxiliary materials in toolboxes to enhance their flexibility, shock resistance, and waterproofing.
