Which fluorescent whitening agent should be used for blow molded products

Blow molding is one of the plastic processing techniques, which has developed rapidly and is generally referred to as hollow blow molding. Blow molding products have a wide range of applications and are also consumables in daily life. The editor of Kunshan Juxinchang Company has learned that it is mainly used as a container for storing food, beverages, skincare products, medicines, and daily necessities.

The commonly seen drinking water buckets are also made of PC plastic blow molded processing, and the blow molded buckets produced have high specifications for the external shape, especially whether the appearance is clean or not. This product standard directly affects the sales volume and competitiveness of blow molded products, so choosing a suitable whitening agent is particularly important.

Firstly, mastering the plastic blow molding processing technology is relatively simple compared to other plastic processing technologies, with five basic processes involved

1. Plastic preform;

2. Close the petal shaped grinding tool on the embryo, clamp the grinding tool and disconnect the embryo;

3. Inflate the cold wall of the mold core, adjust the opening, and maintain a certain working pressure during the cooling period;

4. Turn on the grinding tool and remove the blown parts;

5. Repair the burrs to make finished products.

The above is the process flow of blow molding processing. The process of adding whitening agents involves mixing the materials before production and manufacturing, using a mixer to mix evenly, and then proceeding with production and processing. By utilizing this meticulous processing technology, whitening agents can have significant whitening and brightening effects.

So, which whitening agent to choose?

The most effective whitening agent commonly used on PC blow molding barrels nowadays is OB-1. It can make blow molded products achieve bright colors that satisfy customers.

One basic characteristic of whitening agent OB-1 is its exceptional heat resistance, which matches the production and manufacturing temperature of plastic blow molding. Moreover, it has good reliability and is not easily prone to yellowing. It has high compatibility with plastic and a more significant whitening effect.

In addition, the cost of using fluorescent whitening agents is relatively low. The editor of Kunshan Juxinchang Company suggests that the daily increase should be around 300 grams per ton of material produced and manufactured. While improving the level of blow molded products, it will not increase the cost too much.
