Fundamentals of plasticizers
Plasticizers bring flexibility to PVC applications. They also attract misconceptions across the value chain. There are indeed similarities, but the truth is that plasticizers can also be fundamentally different!
Plastics and polymers, including PVC, are essential to our quality of life. Many PVC products need to be flexible and soft to withstand physical stress without breaking. They also need to be able to take a particular shape for each and every application.
As the third largest polymer consumed, PVC enhances the quality of our daily life.

Different PVC needs for different markets
Plasticizers transform the properties of PVC to create the attributes we need in each application.
Most PVC applications have a life-span of 10 to 20 years and beyond. Its long life-span makes PVC the perfect material for applications like building and construction.
What is PVC?
PVC has all the attributes needed to make it a widely used polymer. It is:
energy efficient: it takes less energy to produce than many alternative plastics3
cost effective
flame retardant – inherent fire safety, due to chlorine
durable: applications have long life-span expectancy
versatile, printable and paintable
adaptable: can be processed in multiple manufacturing operations
chemically resistant
recyclable4

What are plasticizers?
Most plasticizers are esters, that make PVC soft, flexible and easy to shape

How does a plasticizer make PVC flexible?
Plasticization is about developing strong forces between PVC and plasticizers.
Looking for a general purpose plasticizer?
Jayflex™ plasticizers show superior performance in the key requirements for a general purpose plasticizer.
ExxonMobil patented DOTP (DEHT) as early as 1953. Because of its poor compatibility with PVC, the company decided not to commercialize it and shifted its focus to other, more reliable solutions.
