Deodorizing effects of sepiolite on odorous volatile organic compounds of natural rubber latex films

This study reports the efficiency of sepiolite in reducing odorous volatile organic compounds (VOCs) from natural rubber. Natural rubber latex (NRL) films with various content of sepiolite were prepared, ranging from 0 to 2.0 parts per hundred rubbers. The presence of odous VOCs in neat NRL films an...
