Selecting Plasticizers for Polymers

Use of Plasticizers in Polymer Applications

Plasticizers are among the most widely used additives in the plastic industry. They are also usually cheaper than other additives used in polymer processing. Plasticizers are most often used in PVC, the third largest polymer by volume after PP and PE. In turn, PVC is used in a wide range of applications. Explore the main application areas where plasticizers are largely utilized.

Overview

Key Applications

Over 90% of the plasticizers used in thermoplastic polymers are used in PVC. The plasticized polymer market and the plasticized PVC market are largely one and the same although some plasticizer is also used in acrylic polymers, polyurethanes, polystyrene even polyolefins. Some of the major end uses are discussed below.

  • Film and Sheeting - Products made from flexible PVC film and sheet include roofing membranes, geomembranes, upholstery, luggage, advertising signs, swimming pool liners and others

  • Flooring - Flexible PVC flooring products include resilient sheet flooring, vinyl composition tile, luxury vinyl tile, vinyl backed carpet tile

  • Wire and Cable - Flexible PVC is a good electrical insulator with good processability and a useful service temperature range hence it is the perfect material for electrical applications such as insulation and jacketing for electrical conductors, insulation for fiber optic cables

  • Coated Fabrics - PVC synthetic coated fabrics offer weather-resistance, and have excellent strength and durability. Used in industries which support architecture, lifestyle, sports, advertising, defense, mining, food & agriculture, automobiles and transportation. Products include tarpaulins, tents outdoor furniture and others

  • Consumer goods - Apparel, footwear, packaging

  • Medical - Blood bags, IV tubing, biohazard containment structures, other medical devices

  • Non-PVC - Small amounts of PVC type plasticizers are used in other polymers including acrylics, polyurethanes, polystyrene

Most plasticized PVC products are durable goods, products with long service lives. Phthalates, because of their low volatility, low water solubility, good resistance to sunlight and temperature extremes, good compatibility with the PVC polymer and generally good resistance to biodegradation, are well suited for use in such products. Examples include:

  • Flexible PVC roofing membranes
  • Geomembranes
  • Wire and cable insulation

Phthalate plasticizers have been very difficult to replace in these end uses. Likewise, because of their relatively high solvating strength for the PVC polymer and relatively low viscosities, phthalate plasticizers have been found to be more easily processed in flexible PVC compounds as compared to at least some of the phthalate replacements.

Note however, that nearly half of the 7 million tons of plasticizer used annually is DEHP and DEHP, a general purpose type plasticizer, can be replaced in many products.
