Do You Know Why Plastic Pallets Fade?

Do you know why plastic pallets fade? Specifically, what caused it? Now, Zhejiang Zhiguang Plastic Pallet Co., Ltd. do you analyze why plastic pallets fade?

One, exposure

Exposure to the sun will make plastic products prone to aging. Due to ultraviolet rays, the tray may fade or even become brittle. Therefore, under normal circumstances, plastic products will add anti-aging during the production process

Agent. However, when using pallets outdoors, it is recommended to control the use time or choose plastic pallets in the blow molding process to better withstand exposure.

Second, toner

Due to general reasons in the market, plastic pallets are usually blue, and the replacement of the materials used in the pallets will also affect whether the plastic pallets will fade. Acid and alkali resistance and oxidation resistance of the material

Very important.

Three, raw materials

Pallets are usually made of high-density, impact-resistant polyethylene, while plastic pallets are made of PP. The different stability of the trays of different materials is also one of the reasons that affect the fading. At the same time, different raw materials

Different melting points, high temperature resistance should be considered when choosing colorants.

Fourth, return materials

Plastic trays made of returned materials have some disadvantages and are more likely to fade than trays made of pure new materials. At the same time, if there are impurities in the material, it is not conducive to coloring.
