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.
This is the role of plasticisers and such process is technically called plasticising. PVC polymer molecules have positive and negative polarities inside, while plasticiser molecules also have such polar and non-polar parts.he PVC polymer molecules and the plasticizer molecules are electrically attracted to each other, and the non-polar parts widen the distance among the polymer molecules to keep softness. PVC products which are softened by plasticisers are called soft (flexible) PVC products.
