Black Masterbatch 40% One of the most widely used types Masterbatch is a polymer in the industry that is produced from a combination of carbon black, base resin and auxiliary additives. With a high percentage of black pigment, this masterbatch provides uniform color, high resistance to sunlight, and improved mechanical properties. 40% black masterbatch has a special place, especially in pipe making, injection parts, film and profile industries.
Black masterbatch compounds 40%
Black masterbatch consists of 40% of three main components:
1. Carbon black (Carbon Black - about 40%)
Carbon soot is the main cause of black color and properties such as:
- Light stability (UV Resistance)
- Absorption of infrared rays
- Increasing strength
- Improving resistance to cracking
provides.
In 40% black masterbatch, High Jet Black or specialized P and N series carbon blacks (such as N220, N330, N550) are usually used, each of which has different characteristics.
2. Base resin (Carrier Resin)
According to the application, the base resin can be of:
- Polyethylene (HDPE/LDPE/LLDPE)
- Polypropylene (PP)
- Polystyrene
- ABS
To ensure maximum compatibility with the final polymer.
3. Additives
In the production of black masterbatch, the following materials are used to improve quality:
- Dispersants for uniform distribution of soot
- Thermal stabilizers
- Lubricants
- Antistatic (in certain applications)
Key features of Masterbatch Black 40%
Using a high percentage of carbon black causes the formation of the following important features:
1. Excellent coloring power
Low consumption and achieving deep black (Deep Black) in film and injection.
2. Excellent UV resistance
Carbon soot is one of the strongest natural filters of UV rays and prevents polymer degradation.
3. Improvement of mechanical properties
Increasing tensile strength and resistance to cracking (ESCR).
4. Uniform distribution of pigment
In film and tube products, it prevents the creation of bright spots or grainy surface.
5. Compatibility with different processes
Stable performance in extrusion, injection, blowing, pipe making and film production.
Applications of black masterbatch 40%
This masterbatch is used in many industries:
1. Pipe industry
- PE100, PE80 pipes
- Water supply, gas supply and telecommunication pipes
- Increasing UV resistance for outdoor use
2. Film and plastic bags
- Agricultural films
- Thick and industrial bags
- Blackout Films
3. Injection parts
- Car parts
- Household appliances
- Electrical parts
4. Profile and sheet
- Construction profiles
- Packaging sheets
- Double-layer and thermoforming products
5. Cable and wire
- Electrical and telecommunication cable casing
- Increasing thermal and optical stability
Important points when choosing a black masterbatch
To choose the best 40% black masterbatch, the following are important:
1. Type of carbon black
N330 carbon black for pipes
N550 for profiles
High Jet Black for injection and appearance parts
2. Melt Flow Index (MFI)
The closer the MFI is to the parent material, the better the fit.
3. Dispersion Grade
Good dispersion preserves mechanical and appearance properties.
4. Moisture and ash percentage
These features show the fundamental quality of carbon black.
summary
Black Masterbatch is 40% of the most important polymer additives, which, in addition to coloring, plays a key role in increasing optical, mechanical and thermal resistance. The quality of carbon soot and its distribution determine the final quality of the product. Due to its high efficiency and optimal consumption, this masterbatch is the main choice of producers of pipes, films, injection parts and industrial products.
