PP (Polypropylene) and HDPE (High-Density Polyethylene) are two common plastic bucket materials that differ in many ways:
Material properties:
- PP plastic buckets have a high melting point, low embrittlement temperature, and good chemical and high t, temperature resistance.
- HDPE plastic buckets have high density, low melting point, high rigidity and strength, good impact, and corrosive ion resistance.
Application areas:
- PP plastic buckets are commonly used in food packaging, pharmaceutical, chemical, and other fields, especially suitable for acid and alkali solutions and high-temperature liquid storage and transportation.
- HDPE plastic bucket is commonly used for storing and transporting liquids and solids, widely used in chemical, petroleum, and food processing industries.
Manufacturing process:
- Polypropylene plastic buckets are usually manufactured by injection molding to produce plastic buckets with better sealing.
- HDPE plastic buckets are usually blow-molded to produce buckets with a certain degree of toughness and impact resistance.
The choice of plastic bucket material must be based on the specific use and need. If acidic or alkaline or hot liquids need to be stored, polypropylene plastic buckets may be more appropriate. High-density polyethylene plastic buckets may be more suitable if greater strength and impact resistance are required.
