Masterbatch is a concentrated pellet product obtained by thoroughly blending high-concentration pigments, additives, or functional additives with a carrier resin.
Through pre-dispersion of the materials and strong shearing in a twin-screw extruder, a granular concentrated masterbatch is produced. This masterbatch offers advantages such as high dispersion, low addition rate, and environmental friendly(dust-free).
According to different plastic products’ application, masterbatches can be made with different carriers to ensure 100% compatibility between the masterbatch and the basic resin.
The main functions of master batches:
✔ Providing custom colors and color consistency for plastic products
✔ Improving extra properties of materials (such as anti-static, UV resistance, flame retardant, etc.)
✔ Improving processing efficiency and product yield
✔ Precisely controlling the amount of additives and simplifying the production processing
① Main Contents
Customized Carrier Resin — The key factor for compatibility with the base material, such as PE, PP, PET, ABS, PA, TPU, etc.
Pigments or Functional Additives — Provide color and specific properties, such as UV resistance, antistatic properties, flame retardancy, etc.
Dispersing Agents and Processing Aids — Ensure uniform pigment dispersion and stable processing.
The Main Categories and Applications of Master Batches
Color masterbatch is the most commonly used in plastic parts. Through the uniform dispersion of pigments in carrier resins, it achieves color control and good effects in plastic products. It is suitable for films, non-woven fabrics, wires and cables, pipes, plastic containers (bottles), injection molded parts, and other products.
Customized Colors:
More colors than standard options, such as company brand colors and exclusive color codes, like RAL color code or Pantone color code, and in the same time we can match color according RGB data to save sample shipping fee and time.
⚫ Black Masterbatch — Covers a variety of carriers, applications, and regulations with high concentration, high dispersion.
⚪ White Masterbatch — Provides bright white color, high opacity, and high dispersion effect; white masterbatch concentration up to 70-75%, covering a variety of carriers.
With the increase of improved product performance, functional masterbatches are becoming more widely used, enhance plastic with various special functions.
Main functions include:
UV/Weathering Resistant Masterbatch — Lengthen the lifetime of outdoor products, reduces color fading, and delays resin chalking in outdoor.
Antistatic Masterbatch — Reduces the risk of static electricity buildup, suitable for films and electronic shell.
Flame Retardant Masterbatch — Improves the fire resistance of materials, reducing property damage and personal injury.
Filler Masterbatch (such as calcium carbonate masterbatch, talc masterbatch) — Reduces costs and can also improves mechanical strength.
PPA Masterbatch — Improves film surface smoothly, lower melt fracture, and reduces the frequency of die cleaning.
The following factors are very important when choosing a masterbatch:
✅ Carrier Compatibility — The carrier resin must match the target plastic.
✅ Processing Method — Non-woven fabrics/films/pipes have different processing process, requiring different grade masterbatches.
✅ Product Application — According to the application, to confirm if the masterbatch need UV resistance, antistatic properties, flame retardancy, etc.
✅ Color Stability and Dispersion — Affects the product’s appearance and processing consistency
✅ Let-down ratio — Affects the final performance and total cost
Regulatory Requirements - Applicable to food, children's toys, water treatment, etc., all need specific regulations.
We can provide technical selection advice based on your basic resin type, thermoforming method, and end application.
Packaging Films( cast film, blown film) — High color fastness, anti-static, fewer crystal points, no black spots, no migration, etc.
Injection Molded Products — Correct color, high color gloss and UV resistance
Plastic Pipes — Long-term weather resistance, food grade, boiling water resistance, etc.
Automotive Parts — Anti-aging, color difference control.
Automotive parts are typically have very strict color ΔE requirements, such as ΔE < 0.3 for black and gray. Depending on the project, some may require separate control of LAB datas.
Electronics/Small Appliances — Antibacterial, extremely high requirements for color consistency, black spots.
1.What makes Standex different from other masterbatch companies?
Standex's technical, sales, and production all staffs are come from American masterbatch companies. We have 17 years of experience in the masterbatch industry, accumulated a great deal of industry experience.
Based on customer needs, we provide all-round solutions quickly and efficiently. This ensures you zero risk.
2. How do I choose the right masterbatch for my product?
When choose the masterbatch, you need to consider: the compatibility of the base and carrier resin(such as PE, PP, etc.), the product types (outdoor use, food packaging, etc.), the processing method (injection molding, film blowing, etc.), and other required functions (color, antistatic, flame retardant, etc.), as well as any other special regulations. The best choice ensures good dispersion and stable performance.
3. What is the recommended let-down ratio for the master batch?
There is no fixed answer to this question. Usually divided into the following three situations
First, we usually try our best to meet customer's needs, and if we cannot, we will feedback to the customer for adjustments.
However, the typical addition ratio for color masterbatches is 2%-6%; while functional masterbatches likes: UV-resistant and flame-retardant masterbatches may require 3%-10% or even higher.
Other specific ratio should be adjusted based on the desired effect and processing tests.
4. How can masterbatches prevent unevenness, color differences, or agglomeration during processing?
Ensuring good dispersion is key. It is recommended to use masterbatches that are 100% compatible with the base material, and need to control processing during processing, such as processing temperature, screw temperature, and screw speed. Pre-drying the raw materials can also reduce bubbles caused by moisture. Choosing high-quality masterbatches can minimize these problems.
5. What is the difference between masterbatch and pigments/additives?
Compared to direct add pigments or functional additives, masterbatch is pellet form, and mastebatch have the following advantages: dust-free, easy to weight, ensuring more uniform dispersion, and increase efficient of the production process.
Master batch ensures high-quality product, and keep clean hygienic environment for employees in the same time. This is a win-win method.
6. Can the masterbatch be used for food-grade or hygiene industry? Are there any certification standards?
Yes, we can provide masterbatch that meet different applications and requirements, including food contact grade, medical grade, or masterbatches certified to ROHS/REACH.
Specific requirements can be customized according to customer needs, and relevant technical data sheets (TDS) and safety data sheets (MSDS) will be provided together.
7. How long does sampling take?
For standard masterbatch usualy we have stock, we can ship out in the first day.
