Master-batches - Introduction
Master-batches, also known as Master-batches, are additives used to color materials such as plastics and rubber. It is made by mixing a pigment or dye with an appropriate amount of a carrier resin (usually polyethylene or polypropylene). Master-batches have the following properties:
1. Color stability: The pigments or dyes in Master-batches have good color stability and can keep the color in the material unchanged for a long time.
2. Dispersion: Master-batches can be evenly dispersed in the material during processing to ensure uniform coloring effect.
3. Good solubility: Master-batches have good compatibility with materials and can be fully dissolved or dispersed with materials.
The main uses of Master-batches include:
1. Plastic Products coloring: Master-batches are widely used in the coloring of plastic products, such as plastic containers, packaging materials, furniture, etc.
2. Rubber products coloring: Master-batches can also be used for coloring rubber products, such as rubber seals, rubber tubes, etc.
3. Create special effects: some Master-batches can also create special effects, such as metallic luster or fluorescent effect.
The preparation of Master-batches generally includes the following steps:
1. Material mixing: Pigment or dye is mixed with appropriate amount of carrier resin in proportion.
2. Melt mixing: Heat the mixture to a molten state to ensure that the mixture is fully mixed.
3. Granulation: the molten mixture is cooled by the granulation equipment and cut into granules.
In terms of security information, Master-batches are generally safe, but the following recommendations need to be followed:
1. Avoid inhalation: Avoid inhaling dust or mist when handling Master-batches.
2. Avoid contact with skin and eyes: Avoid direct contact of Master-batches with skin or eyes. If contact occurs, rinse with water immediately.
3. Storage and handling: Master-batches should be stored in a dry, cool place, away from fire and flammable materials.
4. Follow the manufacturer's instructions: When using Master-batches, you should follow the safe operation guidelines provided by the manufacturer.
Overall, Master-batches are a convenient and effective coloring additive with good properties and a wide range of applications.
