I'm currently in the market for high-quality colour changing thermochromic pigments suitable for extrusion processes. I'm particularly interested in pigments that exhibit vibrant and consistent color shifts when exposed to varying temperatures. It's important that these pigments not only perform well but also maintain their properties over time and under different environmental conditions. Additionally, I would appreciate information on the available color options, packaging sizes, and minimum order quantities. If you have any technical data sheets or product samples, that would be helpful in my evaluation process. Looking forward to your prompt response with details on pricing and lead times, as I'm eager to move forward with this project.
