3. Outer appearance: Ivory-white, Have no flaw.
4. Shape: cylinder grain
5. Additive dosage: =3%
(1)Improve products' smoothness, transparency and evenness.
(2)Improve output and reduce energy consumption.
(3)Reduce outer defects such as familiar melt fracture.
(4)Reduce or eliminate phenomena of material deposit in die opening.
(5)Permit to extrude temperature sensitive resin or resin of low temperature.
(6)Prolong continuous machining time.
(7)Reduce the phenomena of gel during the process of extrusion.
(8)Reduce the color-switching time.
(9)Eliminate the phenomena of wire-drawing resonance, reduce filament break, improve legging efficience, excellent pigment strength,improve product's glossiness.
7. Operational principle of Polymer machining pigment masterbatch.
Under the effect of potential difference, fluorine-containing polymer may move to outer of melt and cling to metal's appearance, during the extrusion process of pigment masterbatch of additive polymer machining. And then a lubricating layer will be produced between metal wall and melt. This lubricating layer is in homeostasis during the continuous entrusion. The extrusion quality and production quality will be stable after the homeostasis is stable.
8. Inuring time of Polymer machining Pigment masterbatch
The pretreatment equipment which has high content of pigment masterbatchcan be adopted first so that the balanceable time is 15-20 minutes. The pigment masterbatch of common chroma can also be used directly. It usually takes into effect in 30-60 minutes.
9.Does Pigment masterbatch and other accessory ingredient bring into play.
In the acknowledged typical receipt, it doesn't influence the acting of other accessory ingredient's functions at present.
