Plasticizers: Types, Uses, Classification, Selection & Regulation
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 products. Examples include:
A Strategy for Nonmigrating Highly Plasticized PVC
Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the...
Application of ionic liquids as low-volatility plasticizers for PMMA
Plasticizers are used to improve flexibility, reduce cost and improve the processability of polymers. Ideally, plasticizers would be low in cost, compatible with the host polymer and be easily processed. For extending the lifetime of plasticized materials, the additive must have a low volatility and not leach from the host.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
Impact of alternative materials to plasticized PVC infusion
Alternative plasticizers like Diisononyl Phtalate (DINP), Di-(2-Ethylhexyl) Phtalate (DEHT), 1,2-cyclohexane dicarboxylic acid diisononyl ester (DINCH) or Tris(2-Ethylhexyl) trimellitate (TOTM
- What makes a good plasticizer?
- Ideal plasticizers should be highly compatible with polymers, stable in both high and low temperature environments, sufficiently lubricating over a wide temperature range, insensitive to solar ultraviolet (UV) radiation, leaching and migration resistant, inexpensive and should fulfill health and safety regulations.
- Are polymeric plasticizers a good choice?
- They can be designed so that they are highly compatible with the host polymer, and leaching and volatility issues have been significantly improved over traditional plasticizers. However, polymeric plasticizers are usually expensive and have lower plasticizing efficiency than most traditional plasticizers.
- Are biopolymers a good substitute for conventional plasticizers?
- The use of natural and/or biodegradable plasticizers, with low toxicity and good compatibility with several plastics, resins, rubber and elastomers in substitution of conventional plasticizers, such as phthalates and other synthetic conventional plasticizers attracted the market along with the increasing worldwide trend towards use of biopolymers.
- Why do we use plasticizers?
- Plasticizers are used to improve flexibility, reduce cost and improve the processability of polymers. Ideally, plasticizers would be low in cost, compatible with the host polymer and be easily processed. For extending the lifetime of plasticized materials, the additive must have a low volatility and not leach from the host.
- What is the role of plasticizers in polymers?
- The primary role of plasticizers is to improve the flexibility and processability of polymers by lowering the second order transition temperature . Plasticizers are actually low molecular weight (MW) resins or liquids, which form secondary bonds to polymer chains and spread them apart.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
