We have received many enquiries recently, most of them are asking for Thermochromic masterbatch or Thermochromic pigment for moulding/extrusion applications.one of the more typical question is if above products suitable used for PBT moulding ?

Before answer this question, we would firstly ask below 3 questions

  1. 1.What's the specific product ?

  2. 2.What's the color of PBT ?

  3. 3.What's the processing temperature and residence time ?

Normally, customer would reply below answers:

  • 1.Products: Bottle or something else

  • 2.Colour:Natural white

  • 3.Temperature:280C in 30 seconds

Based on above replies, we are afraid that Thermochromic masterbatch or Thermochromic pigment are not suitable for PBT moulding, since there are only PE based / PP based Thermochromic masterbatch available, and if you would like to use Thermochromic pigment, 280C is very high temperature for it.

We hope it helps, if you would like to know more details, please feel free to contact us
