Non-woven masterbatch is a masterbatch made by adding a pigment colorant to a plastic substrate. The substrate is mainly to look at the customer's plastic. Made into a non-woven fabric can be used to produce a variety of plastics, commonly used PP, PET, PA and so on.
The biggest difficulty in using non-woven masterbatch is how to properly add it to the material?
The two main factors are the carrier resin used to produce the masterbatch and its molecular weight, which are often not determined by the company that buys the masterbatch. In addition to some specially requested colors, materials that are potentially destructive to polymer properties are generally not used. Granular color concentrates typically contain 30% to 50% of the colorant, with the rest of the polymer system being a carrier resin. It is essentially an adhesive body as a colorant.
The amount of non-woven masterbatch in the final resin is generally 2%-5%
If the color masterbatch is properly mixed, the content of the carrier resin in the final mixture is 1% to 3% or more.
As a result, it has become the most abundant additive in the additive series, so attention should be paid to the details when selecting the carrier resin.
In particular, the carrier resin and the matrix resin should be chemically compatible.
The best way is to choose the same type of polymer as the matrix resin being filled.
