Polyvinylchloride: Hydrocarbon Plasticizers |
Hydrocarbon based monomeric plasticizers There are various hydrocarbon based plasticizers mainly derived from petroleum and coal tar fractions, however, most of them are unsuitable due to their high odor and poor clarity. Linear Paraffins are used specially in plastisol, due to their low solvency power to depress viscosity, however, the high volatility limits its usage. |
Alkylbenzenes are another type that offers low odor and better clarity, and are mainly used to reduce the viscosity in plastisol. Commercially available hydrocarbon based plasticizers includes Jayflex 210 (Naphthenic Hydrocarbon), Jayflex 215 (Aliphatic Hydrocarbon) etc. |
Other monomeric plasticizers Depending on the processing conditions and/or the expected end use, highly specialized plasticizers are used. For example, TXIB (2,2,4-trimethyl-1,3-pentanediol diisobutyrate) is a non-phthalate plasticizer, that is usually used in plastisol applications to get reduced viscosity. Due to the low initial viscosity and ease of processing, TXIB has found wide variety of applications including, nail care, plastisol, sheet vinyl flooring, toys, sporting goods, vinyl gloves, wall coverings etc. It is a highly volatile plasticizer, thus, offers stain resistance properties to the end product. |
