Thank you for your inquiry.
In general, Thermoplastics are considered latex-free. Copied below are links to websites that give you a more detailed discussion in this regard. Thus, to the best of my knowledge, there is very little if any concern regarding the use of Thermoplastics in latex-allergic individuals. However, it is always best to follow the advice cited in the quote copied below from the latex support group. One of the links copied below leads directly to their website.
Thank you again for your inquiry and we hope this response is helpful to you.
