Advantages of Metallocene EPT Long Lifetime Low Chlorine Content Excellent Mixing Processability Disentangled Molecules Excellent Extrudability Synthetic Extender Oil Less Gel No Deashing Process High Mechanical Property Narrow MWD Narrow Diene Distribution

Long Life by Low Chlorine Content Mitsui Metallocene EPT has longer lifetime by lower chlorine content. Chlorine Content (ppm) 100 50 Chlorine accelerates discoloration and degradation 0 Metallocene EPT Conventional EPT

Degradation of Copper by Chlorine Chlorine accelerates the corrosion of copper. EPT Copper Plate After 120ºC 2weeks Metallocene EPT Conventional EPT

Degradation of Nylon by Chlorine Chlorine accelerates the degradation of Nylon. EPT Nylon Plate After 120ºC 2weeks Metallocene EPT Conventional EPT

Excellent Mixing Processability Molecules of Mitsui EPT are disentangled by extruder. Polymerization in Solution Mitsui Disentangled Molecules EPDM Extruder Other s Production Process (Steam Stripping) Dense Entangled EPDM

Why Synthetic Oil in Mitsui Metallocene EPT? Synthetic oil (Liquid EPR) has better properties 1. Good compatibility to EPDM (Component is same as EPDM) 2. High purity 3. Less low molecular weight component (Prevention of oil vaporization) 4. Stability of viscosity at low temperature

Stable Viscosity of Synthetic Oil Viscosity [Pa s] Synthetic Oil Paraffinic Oil Temperature [ºC]

Excellent Extrudability by Synthetic Extender Oil Synthetic oil extended in Mitsui Metallocene EPT shows excellent extrudability. Comparison of Properties Hardness Extrusion test Paraffinic Oil purity Synthetic Oil Processability Paraffinic Oil Low Temperature Property Volatility Bleeding Synthetic Oil Excellent Extrudability

Less Gel by Metallocene Catalyst Metallocene process doesn t need deashing MCI Metallocene Process Reactor No deashing No Gelation Extruder Others Vanadium Process Deashing by industrial water Oxygen Gelation Reactor Steam stripping

Effect of Oxygen on Gelation Oxygen accelerates gelation. High Experiment Gel Percentage (%) 250ºC 1day Heated Low Concentration of Oxygen (10-3 mmol/p-kg)

Amount of Gel in Polymer Mitsui Metallocene process Mitsui EPT doesn t have any gel. Others Vanadium process Gel Polymer Solvent (decane) Polymer is dissolved in decane at 150 for 4 hours. Decane Net

Quality Improvement by Less Gel MCI; Metallocene process Extruded Others; Vanadium process Extruded
