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.

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)
