Резино-латексные композиции (Rubbur-Latex Compositions)

Hello colleagues!

Need your help here. If any of you have come across the above term, knows how it sounds in English and will be willing to share his/her knowledge, I would really appreciate that :-)!

This is just a table of threshold values I'm translating and the chemical I'm looking to find a translation to is listed in the 'Rubber-Latex Compositions' subcategory. This is as much info, as I have.

Thank you in advance.
Заранее спасибо!
