The difference between PE and PP plastic pallets

The main raw materials of plastic pallets are PP and PE. PP: also called polypropylene, is a semi-crystalline thermoplastic. It has high impact resistance, strong mechanical properties, resistance to a variety of organic solvents and acid and alkali corrosion. It is widely used in industry and is one of the common polymer materials. Mainly used to produce plastic pallets, plastic tables and chairs, and plastic trash cans. Plastic film, etc. PE: The scientific name is polyethylene, which is one of the most commonly used polymer materials in daily life. Polyethylene is resistant to a variety of organic solvents and a variety of acid and alkali corrosion, but it is not resistant to oxidizing acids, such as nitric acid. Polyethylene will be oxidized in an oxidizing environment.

What is the difference between PP and PE plastic pallets? From a physical point of view, PP plastic pallets are more flexible and impact resistant than PE plastic pallets. PE plastic pallets are better. In addition, PP is also higher than PE in terms of temperature resistance. Generally, PP can withstand pasteurization temperature. When used as a film, PP has better transparency than PE. In terms of temperature performance, PE plastic pallets can be used at -70°C, and PP can be used at -35°C. If it is in the fresh and frozen industry, PE plastic pallets are generally used. PP hardly absorbs water, and has high heat resistance and toughness. If used for buckets and cups, PP material is better than PE material; but if used for plastic pallets, PE plastic is better for overall performance considerations .
