Eastman Plasticizers
Eastman’s versatile non-phthalate plasticizers have an extensive toxicological profile and broad regulatory clearances that demonstrate their suitability for many uses. Their outstanding performance characteristics make them an excellent choice when you switch to a non-phthalate plasticizer.

An extensive portfolio of non-phthalate plasticizers for caulk and sealant applications

Sealants and caulks need plasticizers to perform. However, regulatory pressures on phthalates and product formulations have forced sealant and caulk formulators to find alternatives to traditional plasticizer options. Eastman non-phthalate plasticizers promote better low-temperature properties, allow for higher filler loads, optimize adhesion to various substrates, and deliver flexibility and superior performance for sealants and caulks.

Eastman offers a broad selection of non-phthalate, high-solvating plasticizers to help sealant and caulk manufacturers meet the most challenging performance and regulatory requirements.

Eastman plasticizers for
Adhesives & Sealants
For example, for polysulfide sealants, Eastman VersaBond™ plasticizer offers improved Shore A hardness and tensile strength. For other caulk and sealant applications, Benzoflex™ plasticizers offer lower volatility and better viscosity relative to other traditional phthalate plasticizers. And if you desire an exceptionally low viscosity for your formulation, Eastman TXIB™ formulation additive is another great solution. All of these plasticizers are non-phthalate and require little to no reformulation.

Case Studies from Eastman non phthalate plasticizers

Switch to a high performance non-phthalate solution for polysulfide sealants case study

Looking for a non-phthalate option for your polysulfide sealant?
Eastman VersaBond™ plasticizer is a highly efficient non-phthalate solution for polysulfide sealants.
As a near drop-in replacement for traditional phthalate-based plasticizers, VersaBond:

  • Is a non-phthalate plasticizer which is unaffected by any current or known upcoming phthalate restrictions likely under REACH
  • Outperforms other phthalate and non-phthalate options thanks to optimized Shore A hardness and better tensile properties to glass
  • Requires little to no reformulation, which can save months in development, approval and changeover time
