Do Foaming Agent Affect Plastic and Rubber Product Color?

In my communication with our customers especially #manufacturers, they told us after use AC foaming agent, the finished product such as pvc sole turns to slightly yellow, and they ask why ? Here we give our points accordingly to our experience for your reference.

??Foaming Agent Chemical Composition

The specific #chemical makeup of the foaming agent can influence the final color of the product. Some foaming agents may react with other components, leading to discoloration.

??Foaming Agent Dosage

The amount of foaming agent used can also play a role. Higher dosage might alter the color more significantly than lower amounts.

??Processing Conditions

Factors such as temperature and pressure during processing can impact how the foaming agent interacts with the base materials, potentially affecting color.

??Additives

If the plastic or rubber contains colorants or other #additives, the interaction between these and the foaming agent can lead to changes in hue or saturation.

??Aging and UV Exposure

Over time, foaming agents can contribute to degradation, especially under UV exposure, which might change the color of the final product.

All these factors will affect finished products color. If you face same confusion, you can refers to us for suggestion and solution.?? ??
