Studies on the Physical Properties and Application of EPDM-Polymer Blends. Part 4. Physical Properties for EPDM-NBR Blends

EPDM과 각종(各種)Polymer의 Blend에 의(依)한 성능변화(性能變化) 및 그 응용(應用)에 관(關)한 연구(硏究)(제4보(第4報)) EPDM과 Acrylonitrile-Butadiene Rubber의 Blend에 대(對)하여

As a series of the studies of EPDM-Polymer blends, the experiments are concentracted to the investigation of the physical properties of the EPDM-NBR blends. The results are shown as follows; 1. As EPDM addition ratio is increased, the physical properties such as resistance to ozone and aging have also improved, on the other hand, elongation and abrasion resistance decreased. 2. Tear strength is less influenced by blending and character after aging exhibited the same result. 3. Tensile strength decreased with increase in EPDM contents, especially the ratio of EPDM/NBR are 50/50 and 75/25.
