Application of metal-organic framework in odor removal performance of rubber sealing strips

Metal-organic framework materials(MOFs) were used as deodorizers for ethylene-propylene-diene rubber（EPDM） sealing strips, and the effects of MOFs on curing behavior and mechanical properties of EPDM were studied. The inhibition effect of MOFs on the odor of volatile organic compounds released by EPDM was also investigated. The results showed that addition of MOFs could promote vulcanization of EPDM and its mechanical properties remained basically unchanged. MOFs had a good adsorption effect on odor molecules, such as organic amines and carbon disulfide, and the odor level of EPDM had decreased from 4.5 to 2.0.
