Master Batch: |
|
The most common method to produce colored plastic parts is to add color materials to press machine feed as the granules based on primary substance. Sometimes these additives not only produce desired color in total product, but also are able to improve physical and mechanical qualities.
|
|
|
|
Master batch is a kind of plastic mixture including high level of pigment which a tiny amount of it will be mixed with the root of resin or the main mixture to produce total and desired color. |
|
|
|
In mixtures which are produced for extrusion or other similar products, it is possible to catch different color shades by changing thickness and amount of master batch. |
|

|
|
 |
Compound: |
|
Compound is called to a mixture of basic polymer and its additives. This mixture is suitable for processing and production of total product. |
|
|
 |
|
|
 |
Anti-Plaque: |
|
t is a solid chemical substance which is added to plastic mixtures to avoid adhesiveness between the surface of plastic films to each other or to processing machinery. This product can be produced with various technical qualities. |

Filler: |
|
It is a kind of substance which is added to products to decrease cost price or improve physical features of polymer mixtures such as stability, firmness and shock absorbing. |
|
|
|
Fillers differ from reinforcers. Particles of filler are generally small and they do not clearly increase stretching stability of mixture, but reinforcers increase stretching stability of mixture considerably. |

|
|
 |
Slip, Slipping Factor: |
|
It is a kind of improving additive substance which is used as the inner lubricant. The substance covers the surface of product during the process or immediately after its conclusion and decreases friction. |
|
|
 |
|
|
 |
Pigment: |
|
It is a general word which refers to all organic or mineral or natural or artificial color substances which are used in plastic industry.
|
|
|
 |
|
|
 |
Titanium Dioxide: |
|
It is a white powder that is produced in two crystal forms of anatase and rutile. This substance is widely used as the pigment in heat-resistant materials.
|
|
|
|
If this substance is used to produce white color, it should be applied lonely, but to produce other colors, it should be used with other pigments. |
|
|
|
The substance is neutral chemically and is resistant against heat and leakage. Rutile has higher refractive index and has more tarnish power. |
|
|
 |
|
|
 |
Granule: |
|
Granule is called to molding mixtures that are produced as small pills of sphere or cylinder. |
|
|
 |
|
|
 |
Pp: |
|
Pp is a heat-soft resin that is produced by polymerization of propylene with some catalysts such as aluminum alkyl and titan tetrachloride inside required solvent. This polymer has the lowest density among all kinds of plastic (about 90%). The properties of propylene polymers such as poly-ethylene are various widely according to molecular weight and production method. |
|
|
|
Poly-propylene is good resistant against heat, water, chemical substances and folding with low frequency and is used widely in textile industries. |
|
|
 |
|
|
 |
ABS: |
|
ABS is
called to heat-soft substances which include terpolymer
acrylonitrile butadiene and styrene or physical mixture of
acrylonitrile-butadiene lastics and styrene-butadiene
resins. |
|
|
|
These substances are hard and resistant against shocks, heat and chemical substances and keep their properties in low temprture and they also are not fragile. This plastic is used for home appliances, automotive parts, electronic products, furniture, gardening accessories, etc. |
|
|
 |
|
|
 |
PE: |
|
This is a group of resins which is produced by polymerizing ethilen gas. By changing catalyst and using polymerisation, PE can be controlled on its physical qualities such as density, crystallization, ramification rate, molecular weight and distribution of molecular weight. |
|
|
|
Poly-ethylenes with the density between 910.0 and 9650.0 are idiomatically called “light poly-ethylenes” (LDPE), between 962.0 and 940.0 are called “semi-heavy poly-ethylenes” and between 941.0 and 965.0 or higher are called “heavy poly-ethylenes” (HDPE). |
|
|
|
Poly-ethylene films are used to pack foods, soft goods, clothes, plastic bags, etc. |
|
Other applications of poly-ethylene are as electrical insulation in wires and cables, household utensils, different parts in car industries, injection parts, etc.

DOP: |
|
DOP is a kind of softener which is applied for vinyl resins and cellulose esters. |
