    2. Petrokemya in summary Petrochemical company, wholly owned by SABIC Established in May 1981, Jubail Ind. City Main Products: Ethylene 1-Butene Propylene 1,3-Butadiene Benzene Polystyrene Vinyl Chloride Monomer (VCM) Polyvinyl Chloride, (suspension & emulsion ) S-PVC & E-PVC Polyethylene, ( linear low density & high density ) LLDPE & HDPE Hydrogen ( by-product )

    3. Quality Assurance Department Mission: to provide continuous analytical support to all Petrokemya plants Divided into: Olefins area VCM area PVC area Polyethylene area

    4. Polyethylene Grades of PE: Linear Low Density Polyethylene (LLDPE) 118N film application 118W film application 218W film application 318B film application High Density Polyethylene (HDPE) F00952 film application F00952EQ film application F01552 film application BM1052 blow molding application Ciba® IRGANOX® 1076 is a monofunctional hindered phenolic AO. The product offers effective protection against overbake yellowing by terminating free radicals. It is especially suitable for a broad range of binder systems. Ciba® IRGANOX® anti-oxidants are phenolic based anti-oxidants that hinder thermally induced oxidation of polymers where high temperature applications are used. Unlike hindered amines, anti-oxidation is consumed - and not regenerated - in the stabilization process. Ciba® IRGANOX® 1076 is a monofunctional hindered phenolic AO.

    6. Tests of Polyethylene Melt index (MI): an indicator of molecular weight, through a calculation of time of extrusion Melt flow ratio (MFR): an indicator of the molecular weight distribution, through a ratio of melt flow rate (MFR) to melt index (MI) Density: an indicator of crystallinity of the polymer.

    7. Tests of Polyethylene Color: a measure of what is physically acceptable to the customer Additives content: a measure of the amount of stabilizers being added to the resin, using XRF & FTIR Fan: a measure of gels of imperfections in the product

    8. Tests of Polyethylene Ash: determines the inorganic content of PE by burning the polymer portion Contamination: determines the contamination caused by oxidized resins or external factors (dirt, metal, etc.) Pellet Uniformity: checks if pellets are reasonably uniform in size to avoid extrusion problems at customer location (I didn’t perform these three particular tests, but I witnessed them)

    9. Case studies Flow index(FI) and melt index(MI)
