(1)Carrier

Carrier resin carrying pigment, is a material which even disperse the pigment with the action of dispersant and processing modifer. Some  PVC color masterbatch imported is adopted special polyester as carrier. Normally it is also used PVC as carrier by choosing suspersion method with good fluidity.

(2)Plasticiser

Molecules among polar PVC is great attraction, high viscosity, difficult melt and fluid, so it need to add plasticiser to reduce the action of molecules for resin, then to reduce the melt temperature and viscosity of PVC resin. In view of the hard and soft of masterbatch , it can add a kind or several compands  plasticiser as per requirement.  Normally DOP with good commonality is used as main
plasticiser, and epoxy compands with good volatility and stability as auxiliary plasticiser.

(3)Heat stabilizer

PVC is easy to break down with heat to release HCL gas, so it needs to add stabilizer. As color masterbatch is produced by twice-screw extruder, so it requests higher harsh for the heat stability of resin series.

(4)Working modifying agent

As color masterbatch, ideal fluidity should exceed natural pigment, namely masterbatch viscosity is lower than the natural pigment, so that it has even coloring. Adding high density pigment will largely increase the voscosity of PVC. Specially, when adding carbon with difficult dispersion and high oil adsorption, the series voscosity is still very high, since adding very high compands plasticiser. It will reduce effectively series melt viscosity by choosing suitable processing modifer, so it wil benefit for dispersion of pigment to ensure the stability of continue processing.

(5)Lubricant

In PVC resin, it needs to add inner and external lubricant and should keep balance in inner to reduce the highest torque of resin melting.and ensure the brightness of product apperance.

(6)Paint

PVC coloring  is nomally adopted inorganic and organic pigment. As PVC will break down to release HCL gas when it is in high heat, it will make some low acid-resistance colorant to change color, so the pigment used in PVC should meet as follows:
a、temperature tolerance,requesting pigment process not to be decomposed between 160~220℃ ;
b、be unacted on By HCl;
c、good  migration-resistance
d、resistance to elements good;
e、cheap and good。

If discrepancy exists between the English texts and the Chinese texts, the Chinese texts apply.

Formula component:

Calcium carbonate 85%
LDPE  10%
HDPE  5%
Couplint agent   0.5%
Whiteruss    4%

Masterbatches technical data:Density ≤1.7 g/cm3、Moisture content ≤0.2%、Melt flow rate 5~10 g/10 min、Granularity (3×3×4)mm。

The carrier resin of the formula  is LDPE and HDPE。The carrier resin of normal masterbatches may be a kind or more than resin compound, the usage rate of the carrier is around 15%~30% of  the quantity of masterbatches。

We have set up the Customer Service Centers in CN and TW, which can provide the customer with sophisticated technical consulting, repair and services.

Free training shall be provided on site for whole installation and commissioning period.

Color Masterbatches formulation:

Main ingredients:Paint + Carrier + Additive = Color Masterbatches

To be used as a guide only. Some variations in detail are possible.

The use of Masrerbatch has dominated the market ,it is obvious that to dye and change the nature of the plastic material with the Masrerbatch is quite a potential market and a certain trendency .

Masterbatch plastic & color masterbatch

Plastic masterbatch, is the extraordinary quantity of plastic additives contained in the attached and made of resin-enrichment; manufacturing plastic products, do not have to join the types of plastics additives, while adding only the mother can be expected. As a result, it is in today’s world of plastic applied additives in the form of one of the most important. The advantage is: a simple process, easy to use, easy to achieve automation to increase productivity and avoid environmental pollution, will help health workers in the clean and civilized production.

Plastic masterbatch, including:

1. Masterbatch filling;
2. Masterbatch;
3. Retardant masterbatch;
4. Stabilization of polyolefin masterbatch;
5. Functional use of plastic sheeting masterbatch;
6. Masterbatch other dedicated, And so on.

Has broken down dozens of plastic masterbatch. Application: China is the world’s largest plastic, plastic products have been produced more than 21,000,000 tons. Ultrafine-mineral filler at least a year more than 2,100,000 tons of plastic products for a variety of.

China is a large agricultural country, plastic greenhouse film in the use of more than 140 million tons of plastic film in the demand for more than 60 million tons of plastic products for agricultural use in more than 300 million tons (plastic water pipe, spray micro-irrigation, under the membrane Drip irrigation pipe and tube set, light and the stiffness of large plastic pipes, water conservancy construction in a variety of geomembrane and geotextile Bianzhi Bu and composite materials, and non-woven composite geomembrane, Fisheries and Fisheries plastic products, etc.). China’s annual output of plastic packaging materials 3,600,000 tons,

including:

1. Plastic bags;
2. Packed with plastic and tied Zhasheng;
3. Turnover plastic boxes;
4. Hollow plastic containers;
5. Plastic bag;
6. Plastic film;
7. Foams;
8. Wangdou plastic;
9. Plastic hose;
10. Composite plastic irrigation, and so on.

China’s annual output of plastic products for daily use around 3,200,000 tons, including: leather and diaphragm, plastic shoes and plastic soles, plastic furniture, kitchen utensils and other, refrigerators, freezers plastic products, washing machines, plastic products, small household appliances with plastic Products, disposable medical supplies, plastic application of artificial organs, repair, with embedded polymer materials, plastic products and cultural, recreational use of plastic products. China’s plastics used in construction, industrial facilities (automobiles, communications, computers, home appliances, wire and cable, etc.) the use of plastic in the volume are even more alarming.

Plastic masterbatch, as in today’s world of plastic applied additives in the form of one of the most important, and China’s plastics processing industry, belongs to the Chaoyang Industry.
