Giving a job description of a cinematographer is a bit difficult because the term cinematographer can apply to various jobs ranging from camera operator to director of photography. Most often, the term refers to the director of photography, or top cinematographer on a film, so let's focus on that.
Thermoplastic Polyolefin Elastomer (TPO (POE)). Thermoplastic polyurethanes (TPU) are a class of polyurethane plastics with many useful properties, including elasticity, transparency, and resistance to oil, grease and abrasion. Technically, they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
The most common are: diisononyl phthalate (DINP), diisodecyl phthalate (DIDP) and di-2-ethylhexyl phthalate (DEHP, sometimes also referred to as DOP),which have the well balanced properties described above. These plasticizers account for about 75% of all plasticisers used for PVC. Apart from phthalates, several other kinds of plasticisers are used to meet specific requirements, including adipates for low temperature resistance and trimellitates for heat resistance.
