What İs PVC?

PVC (Poly vinyl chloride) is obtained by polymerization of petroleum or agricultural based ethylene and sea salt based chlorine monomer vinyl chloride. Main polymerization techniques are mass polymerization, emulsion polymerization, micro suspension polymerization or suspension polymerization. Raw material is solid and white powder form.

PVC is the most produced third plastic/polymer after polyethylene (PE) and polypropylene (PP). PVC is non-flammable due to structure and resistant to chemicals. PVC Production is easier then alternatives and PVC have various applications regarding to chemical and physical properties. With different types of additives PVC can be functionally used between -60°C and +125°C in our daily life.  

PVC is categorized into two categories as soft ( P-PVC) and rigid (U-PVC). According to this categorization applications varies and differs. Rigid PVC is mainly consumed in buildings pipe, fittings, door and window profiles. Soft PVC is mainly consumed in cable, appliances, automotive and building industries.

PVC is a hard plastic due to its nature. Plasticizers (DOTP, DINP etc.) are added to soften PVC. In addition in case organic and inorganic additives are added to PVC, functional properties are obtained such as UV resistance, hot/cold resistance and chemical resistance in granule form. 

For end product, PVC is formed with injection or extrusion technologies. Powder or granule PVC is consumed in injection or extrusion. Especially soft and semi-rigid PVC mixtures are consumed in granule form for continuous and regular flow to machinery.
