The heat resistance rating of a specialized masterbatch is generally matched to the plastic resin used for the finished product, allowing for safe use under normal operating temperatures. However, varying degrees of discoloration may occur in two specific situations: when the temperature exceeds the normal operating range, or during prolonged machine downtime.
What is the difference between coloring via pre-colored pellets (compounding) and coloring via masterbatch?
Compared to using pre-colored pellets, coloring with masterbatch offers the following advantages:
1. Coloring and product fabrication are completed in a single step; this avoids the additional heating cycle associated with pre-colored pellets, thereby helping to preserve the quality of the plastic product.
2. It simplifies the manufacturing process for plastic products.
3. It results in significant energy savings.
Do products colored with masterbatch never fade?
No product is completely immune to fading; products colored with masterbatch can still fade, though the extent varies depending on the product grade-ranging from clearly noticeable to barely perceptible.
