Effect of natural zeolite as substrate filler on the properties of NBR/EPDM blend

Abstract

The NBR/EPDM blend has great ozone, oil, and heat resistance. Carbon black is the most common used filler material for rubber goods. But, it is less environmentally friendly and less healthy friendly. In this study, it would be studied the use of natural zeolite as a substitute for the filler. This blend was carried out by a two-roll mill and tested by rheometer and tensile strength tester. From the research that has been done, it was known that vulcanizate with carbon black was better than all of the vulcanizate using zeolite as filler substitute. Vulcanizate with CB provided the fastest curing time, the fastest reaction speed and also the best mechanical properties. Vulcanization with the 10 phr zeolite gives the optimum curing time and the best mechanical properties compared to the substitution of other fillers. This shows that 10 phr zeolite (16.7%) can be a suitable filling material for NBR/ EPDM blend.

Ketahanan Termal dan Ketahanan Perendaman Komposit NBR/EPDM dengan Berbagai Kompatibiliser

“…EPDM merupakan karet yang cenderung non polar dan kepolarannya bergantung dari kandungan ENBnya (5-ethylidene-2-norbornene). EPDM memiliki ketahanan yang baik terhadap ozon dan panas, namun kurang tahan terhadap minyak dan oli [1,2] . Pembuatan komposit dari NBR/EPDM dapat meningkatkan sifat unggul dari kedua material tersebut [3] .…”

“…Dari pengujian diketahui bahwa NBR 100% memiliki ketahanan terhdap pelarut yang paling unggul, baik dalam IRM 903, toluene, maupun n-heksana. Hal ini sesuai dengan penelitian sebelumnya yang menyatakan bahwa NBR memiliki ketahanan terhdap pelarut yang baik [1] . Sedangkan EPDM memiliki ketahanan terhadap pelarut yang kurang baik.…”

The Effect of Compatibilizer on the Mechanical Properties and Compression Set of NBR/EPDM Composite

“…There are some previous studies about NBR/ EPDM composite. Jovanovic et al studied the effect of carbon black on NBR/EPDM [3], Mayasari et al studied the effect of zeolite as substitute filler on NBR/EPDM [9], Kaizer et al studied the effect of nanoclay on NBR/EPDM [1]. But based on the authors' knowledge, there is no specific research about the effect of compatibilizer on the mechanical properties of NBR/ EPDM composites, especially using MBS, montmorillonite (MMT), and silica.…”
