Pembuatan bahan pengganti untuk compound EPDM reguler untuk pembuatan cover relay diperlukan komposisi baru dengan menggunakan compound reclaim sebagai compound pengganti atau alternatif ke-2 ( dua) jika terjadi kelangkaan atau keterlambatan kedatangan bahan utama (compound EPDM reguler). Compound reclaim akan dilakukan percobaan pencampuran komposisi/perubahan komposisi sehingga akan mempunyayai sifat yang sama dengan compound reguler. Dilakukan pencampuran bahan dengan perbandingan reclaim 4 reguler 1 juga berpengaruh pada sifat mekanik, tensile strength 69,7 kg/cm2 menjadi 109,6 kg/cm2 , elongation break 385% menjadi 533,3%, spesific gravity 1,0946 gr/cm3 menjadi 1,0748 gr/cm3, dan hardness 51-52 menjadi 49-51, dalam pengetesan tersebut membuktikan bahwa dalam pencampuran ini masih menghasilkan sifat mekanik yang sesuai pada toleransi dan standard yang ditentukan seperti halnya pada perbandingan pencampuran komposisi reclaim 3: reguler 2 . Komposisi ini yang akan digunakan dalam proses pembuatan cover relay karena untuk efisiensidan menghemat penggunaan bahan reguler. Karena tujuan utama dalam proses ini adalah untuk mendapatkan komposisi baru sebagai pengganti jika terjadi kelangkaan pada bahan reguler.Downloads
