Detailed interpretation of the characteristics and differences of pallet raw materials

Blow-moulded pallet manufacturers explain the characteristics and differences of pallet raw materials in detail

The next most common pallets on the market are polyethylene and polypropylene.

Blow-moulded tray manufacturers will tell you today the characteristics and differences between the two types of trays.

Both materials have advantages and disadvantages, and different materials are suitable for different industries.

HDPE polyethylene

HDPE (polyethylene) plastic pallets have good cold resistance.

The manufacturers of blow-molded trays observed its color and found that its surface was milky white and to a certain extent translucent.

HDPE advantages

1. Corrosion resistance:

Examples include corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride).

2. Good water resistance:

The material is non-absorbent and resistant to water vapor.

3. Superior impact resistance:

In the range that can be tolerated, the blow tray can have good impact resistance even at minus -40 degrees Celsius.

HDPP polypropylene

High density polypropylene material is non-toxic and tasteless.

It is a milky white highly crystalline polymer with a density of only 0.90- "0.91g / cm3", which is one of the lightest varieties of all plastics at present.

HDPP polypropylene advantages

1. Good chemical stability:

HDPP polypropylene has good chemical stability, hardly absorbs water, and does not react with most chemicals.

2. Good toughness:

Compared with polyethylene, it is softer. Polypropylene has good flexibility and is less prone to cracks.

3.High temperature resistance

Manufacturers of plastic pallets have suggested that for high temperature environments, the resistance of HDPP materials is also very good.

Plastic pallets made of high-density polyethylene are not as heat-resistant as pallets made of high-density polypropylene.

to sum up

Plastic tray made of HDPE polyethylene material, suitable for use in relatively cold industries, with excellent impact resistance;

Plastic pallets made of HDPP polypropylene are suitable for use in relatively hot industries and have good toughness.
