Masterbatch Production Line

Masterbatches has a wide range of applications in the plastic industry, including consumer goods, packaging, home appliances, building materials, automotive, medical and other industries.

Overview

Masterbatches has a wide range of applications in the plastic industry, including consumer goods, packaging, home appliances, building materials, automotive, medical and other industries. The masterbatches mentioned here refer to color masterbatches

Color masterbatch is a compounding with certain proportion of organic or inorganic pigment and carrier resin. That is, colored pellets made of evenly dispersed high concentration pigment. In general, the higher the pigment percentage, the more difficult color masterbatch production.

Formula

Color masterbatch is generally added with various organic pigments, the highest proportion is 40%;

Black masterbatch is generally added carbon black, the highest proportion is 55%;

White masterbatch is generally added TiO2, the highest proportion is 75%.

Process

Color masterbatch production can be divided into premixing method and multiple feeding method according to the process characteristics.

Premixing method is relatively simple with high speed mixer.

Multi-feeding method usually uses loss-in-weight feeders for precise raw material feeding,

To improve the quality, all ingredients are generally premixed with kneader to get better dispersion when producing white and black masterbatches.

Advantage

JWELL twin screw extruder adopts narrow gap design for color masterbatch to improve shearing and dispersing ability and ensure compounding quality

To improve the quality, all ingredients are generally premixed with kneader to get better dispersion when producing white and black masterbatches.
