A study on the effect of microwave radiation exposure time on the properties of devulcanized EPDM waste / Norhidayah Ahmad Jalini

The highly demanding of Ethylene-Propylene-Diene Monomer (EPDM) in industries due to its outstanding characteristic such as resistance to oxygen and ozone make the EPDM as one of the fastest-growing general purpose rubber nowadays. However, the demand may cause the increasing of the abundant waste r...
