Santicizer Plasticizers offer all the benefits of high solvating plasticizers including compatibility in multiple polymer systems including PVC, Polysulfide, Polyurethane and Silane Modified Polymers. Because of their high efficiency, less energy is required to fuse PVC formulations. Santicizer Platinum G-2000 Bio-Based Plasticizer
Acclaim | High-performance polyol by Covestro | Covestro AG
Acclaim is a high molecular weight long-chain polyether polyol. It has extremely low mono-ol levels, low unsaturation, and low water content. Its low basicity and acidity make it useful across a wide range of applications as well as in improving the overall properties of prepolymers.
Selecting Plasticizers for Adhesives and Sealants
Plasticizers have been used to give polymers a permanent adhesive character (pressure sensitivity), or to regulate their adhesion-cohesion balance to achieve removability. For example, plasticizers can be incorporated into peelable pressure-sensitive adhesive to soften the adhesive, and thus improve peelability and clean removal.
Plasticizers: Types, Uses, Classification, Selection & Regulation
There are two main groups of external plasticizers: A primary plasticizer enhances elongation, softness and flexibility of polymer. They are highly compatible with polymers and can be added in large quantities. For example: up to 50% of vinyl gloves are made up of plasticizers, which make the PVC flexible and soft enough to wear.
- 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.
- 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.
- 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.
- Do additives improve the performance of polyurethane elastomers?
- Incorporation of additives (plasticizer and filler) improves the performance characteristics of polyurethane elastomers. However, the degree of improvement varies based on the nature of reactants involved. Content may be subject to copyright.

- Which polyurethane elastomers are better?
- Among the polyurethane elastomers prepared, the product obtained from prepolymer C with curative X3 exhibits better strength properties and solvent resistant characteristics than those from other products. Incorporation of additives (plasticizer and filler) improves the performance characteristics of polyurethane elastomers.
- Can polyurethane plasticizer be used for printing ink?
- The results indicated that polyurethane plasticizer were prepared successfully by the partial substitution of petroleum polyols with vegetables oil polyols, castor oil and palm olien, given a very comparable mechanical, optical, thermal and freeze properties.
