PC masterbatch is an efficient resin coloring mixture, which uses PC (polycarbonate) as the carrier resin, incorporates high concentrations of pigments, dispersants, and other functional additives, and is processed through specific processes. The following is a detailed analysis of PC masterbatch:

1、 Characteristics and Performance

Excellent coloring effect:

PC masterbatch has excellent coloring ability, which can accurately control the color of products and meet diverse market demands.

Good dispersibility:

The pigment can be evenly dispersed in PC resin, avoiding the occurrence of color spots and stripes, and improving the appearance quality of the product.

Heat resistance and stability:

PC masterbatch inherits the heat resistance of PC resin, which can maintain stable performance at high temperatures and is not easily faded or deformed.

Environmental Protection and Safety:

Compliant with environmental requirements, non-toxic, odorless, and pollution-free, suitable for application fields with high environmental requirements.

2、 Classification and Application

Category:

According to their different uses, PC masterbatch can be divided into injection masterbatch, blow molding masterbatch, and other types.

According to different functions, it can also be divided into antistatic, flame retardant, anti-aging and other types of PC color masterbatch.

Application:

Widely used in optical materials (such as CD, VCD, DVD discs, computer discs, optical lenses, etc.), construction, office, automotive, medical equipment, and other consumer goods fields.

Especially suitable for coloring plastic products that require high transparency and heat resistance.

3、 Production process and quality control

Production process:

The production of PC masterbatch usually adopts a wet process, including pigment grinding, phase transfer, water washing, drying, and granulation steps.

During the grinding process, a series of technical tests need to be conducted on the pigments to ensure the quality of the final product.

Quality Control:

Strictly inspect the incoming raw materials to ensure that the quality of pigments, carrier resins, and other additives meets the requirements.

Real time monitoring of various process parameters and production data during the production process to ensure stable product quality.

Conduct strict quality inspections on finished products, including testing of appearance, color, dispersibility, and other aspects.

4、 Precautions for use

Dilution ratio selection:

The choice of dilution ratio directly affects production costs and the limitations of processing equipment. Choosing the appropriate dilution ratio can balance cost and equipment requirements.

Color control:

During use, the amount of color masterbatch should be carefully adjusted according to the desired color effect to achieve the best color matching.

Drying treatment:

Due to the sensitivity of PC resin to water, it is necessary to dry the PC masterbatch before use to reduce degradation and prevent foaming.

Avoid reacting with other additives:

When using, it is important to avoid mixing with other additives that may react with it to prevent unnecessary color changes or quality issues.
