Modifying Expectations: Novel Urethane Modifiers Outperform
The modifiers and plasticizers were screened in two common polyurethane systems: (1) a generic 2-K thermoplastic formulation based on a polyester polyol and MDI, and (2) a room-temperature, moisture-cured thermoset MDI-polyether polyol (2000 MW) system.
Eastman Plasticizers for Polyurethanes
And Eastman plasticizers are making polyurethane more versatile than ever before. Our plasticizers help regulate the rheological, thermal, and mechanical properties in polyurethane, making it more adaptable, more pliable, and more extrudable in a variety of applications.

Plasticizers: Types, Uses, Classification, Selection & Regulation
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: Unplasticized PVC (or rigid PVC) is used in applications such as pipes, siding, and window profiles.
- Which plasticizers are used for polyurethane based sealants?
- SANFLEX products are widely used as plasticizers for polyurethane-based sealants. Plasticizers are used in many products. And Sanyo Chemical America plasticizers are making polyurethane more versatile. Sanyo Chemical America makes a variety of plasticizers with an excellent anti-migration property.
- What is a polyurethane plasticizer?
- Plasticizers for polyurethanes are especially designed to have low moisture and a low hydroxyl number to enhance the consistency of the final polyurethane piece or coating. The end result yields higher quality and more reproducible final products.
- Which Eastman plasticizer is best for polyurethane?
- Eastman plasticizers Benzoflex™ 9-88 SG and Benzoflex™ 352 excel in improving performance in polyurethane and other polymer systems as they interact with the polymer matrix. Benzoflex™ 352 is a cyclohexanedimethanol (CHDM) dibenzoate plasticizer commonly used in a variety of hot-melt adhesive applications, based on a variety of polymer bases.
- Why does polyurethane need a plasticizer additive?
- Due to their polymer chemistry composition, polyurethanes often require a plasticizer additive to help the maker reach the desired end product. Lowering the intermolecular tensions between polymer chains can increase the flexibility, toughness, and elongation of polyurethane.
- Does Sanyo chemical America make plasticizers?
- Sanyo Chemical America makes a variety of plasticizers with an excellent anti-migration property. Our plasticizers help regulate the properties in polyurethane, making polyurethane more more pliable and easy to extrude so it can be used in many more applications.
- What is flexible polyurethane used for?
- Flexible polyurethanes can be used in sealant, automotive, 3D printing, aerospace, and other applications. Due to their polymer chemistry composition, polyurethanes often require a plasticizer additive to help the maker reach the desired end product.
