5. Best Practices for Using HDPE Masterbatch
5.1. Mixing ratios
The right mixing ratio of HDPE masterbatch is very important to get the properties without prejudicing material performance. Depending on specific application, processing method, and required characteristics, the percentage of masterbatch used usually falls anywhere between 10% and 30%, generally.
Color masterbatch for HDPE: 1% to 5% is usually added for normal applications. However, the masterbatch may have to be increased to 10% for deep or highly saturated colors. In bright-colored HDPE shampoo bottles, 5-10% of color masterbatch may be needed to give a consistent shade.
HDPE filler masterbatch: It is mostly used between 10% and 30%, depending upon the clear cost considerations and the needed mechanical strength. In HDPE shopping bags, 20-30% filler masterbatch may be used to lower production costs while retaining flexibility.
Additive masterbatch for HDPE: The ratio varies with respect to the function of the additive. For instance, UV stabilizers and flame retardants are generally in the range of 1-5%; against that, some products require up to 2-10% for anti-static or antimicrobial agents.
5.2. Common issues and solutions
Poor dispersion
This issue arises when mixing of the masterbatch with the HDPE resin remains uneven, giving rise to uneven colouring, poor mechanical property, or surface defects.
Reason: The processing temperatures may have been inappropriate, mixing might have been inadequate, or the formulation of the masterbatch was incompatible.
Solutions:
- Use a very good carrier resin compatible with HDPE.
- Mixing should be made correct by changing screw speed and temperature during extrusion or molding.
- Select a well-dispersed masterbatch with optimized particle size for good integration.
In blown film production, for instance, streaks or weak spots may occur, a result of poor dispersion, which can be settled by increasing mixing time together with the right melting temperature.
Color migration
Color migration is the phenomenon whereby pigments and dyes migrate within a plastic or are transferred to another surface, causing fading, bleeding, or uneven colour. Colour migration is common in applications subjected to thermal, mechanical, or solvent influences.
Solutions:
- Use high-performance pigments with heat and chemical stability.
- Properly select carrier resins to promote firm adhesion between pigment and HDPE.
- Apply UV stabilizers in order to prevent fading from sunlight exposure.
For example, color migration is mitigated in HDPE food packaging if food-safe, high-stability pigments that resist leaching into the contents are used.
