PE, PA, PP, PVC, ABS, PS are commonly used material in  plastic injection mold industry

1. PE is a polyethylene plastic with stable chemical properties. It is usually made into food bags and various containers. It is resistant to acid, alkali and salt aqueous solutions, but it should not be wiped or soaked with strong alkaline detergent.
2. PP is polypropylene plastic, non-toxic, odorless, can be immersed in 100C boiling water without deformation or damage, and common acid and alkali organic solvents have little effect on it. Used mostly for food utensils.
3. PS is polystyrene plastic, easy to color, good transparency, and is often used to make lampshades, toothbrush handles, toys, electrical parts.

4. PVC is a polyvinyl chloride plastic with bright color, corrosion resistance, and durability. Due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents in the manufacturing process, its products generally do not store food and medicine.
5. ABS is a plastic polymerized from acrylonitrile, butadiene and styrene. Its color is striking, heat-resistant and strong. It can be used to make keys, buttons, tool holders, TV casings and umbrella handles. Wait.
6. PA is a nylon plastic. Its properties are tough, strong and wear-resistant. It is commonly used in the production of combs, toothbrushes, clothes hooks, fan bones, net bag ropes, fruit packaging bags and so on. Non-toxic, but not in contact with acid and alkali for a long time.
