Analysis of Whitening Agent for Chemical Fiber

Fluorescent whitening agent OB-1 is a special whitening agent for polyester staple fibers produced by chemical fiber factories, which is related to some characteristics of OB-1.

Properties: Yellow or green crystalline powder, melting point about 360 degrees, differentiation temperature over 450 degrees, blue-violet color, stable function, maximum absorption spectrum wavelength 374 nm, with intense fluorescence, emission wavelength 434 nm.

1. High temperature resistance, it is the most widely used plastic whitening agent, whitening agent in the public lover, industry such as building materials, chemical fibers and polyester staple fibers are particularly large.

2. Excessive use of weathering resistance is not good, simple separation, the amount can not exceed the peak.

3. High fluorescence intensity and suitable combination with other types can produce synergism.

Usage and recommended dosage:

1. PVC, PP reclaimed material whitening edge tool, profile addition of about 230 grams per ton, general reclaimed material granulation of about 500 to 700 grams, chemical fiber plant about 450 grams per ton of material.

2. Whitening and brightening of polypropylene, rigid PVC, ABS, EVA, polystyrene, polycarbonate and so on.

According to the old and new materials to determine the added share.

3.The addition of color masterbatch is between 3KG and 12KG per ton.

Now the price of whitening agent used in the industry is very low, the manufacturer's deposit is very strong, the distributor has studied the type of compound, inform us that this formula, in pure powder to participate in a certain amount of titanium dioxide can reduce costs, if it is to participate in other additives, one is not able to withstand temperature, the other is not able to add. The effect of adding whiteness. In other words, cooperation must share the role of orchid powder, the role will be better.
