The advantages of polypropylene injection molding (PP) mainly include the following aspects:
1. Low density: PP has the lowest density among all synthetic resins, only 0.90~0.91g/cm 。 This means that using the same weight of raw materials can produce more products of the same volume, thereby reducing costs.
2. Excellent mechanical properties: PP has good tensile strength and rigidity. Although its impact strength is poor, its mechanical properties can compete with expensive engineering plastics in many fields after modification such as filling or reinforcement.
3. Good heat resistance: PP has the best heat resistance among the five general plastics, and its plastic products can work for a long time at 100 ℃, and can even be used to make utensils for heating food in microwaves.
4. Excellent chemical stability: PP is inert to most acids, bases, salts, and oxidants, and can only undergo changes under the action of a few strong oxidants such as fuming sulfuric acid.
5. Good electrical insulation: PP belongs to non-polar polymers and has good electrical insulation properties. Its water absorption is extremely low, and its electrical insulation is not affected by humidity.
6. Good processing performance: PP belongs to crystalline polymers with good molding and processing fluidity, especially suitable for injection molding of large thin-walled products.
