Velsiflex® Plasticizers
High-performance benzoate plasticizers delivering compatibility, efficiency, and lasting performance across diverse applications.
Velsiflex plasticizers are an environmentally friendly option for formulators looking for an alternative to commodity and specialty phthalate esters. Velsiflex products are based on benzoic acid as a building block and are used in a number of applications, including adhesives, sealants, caulk, coatings and inks, plastisol and various flexible PVC uses.
Velsiflex plasticizers are recognized as high-solvating, polar, monomeric plasticizers. In most cases, they provide superior performance compared to other plasticizers in the area of compatibility with the polymer, efficiency or desired softness and the overall permanence of the ester staying in the polymer. Velsiflex plasticizers are performance enhancing low-to medium-viscosity fluid esters in a wide range of plastic additive end uses.
Velsicol is a world-renowned manufacturer of dibenzoate plasticizers and first introduced them in the 1950’s throughout the globe. Velsicol played a key role as a dibenzoate supplier in the conversion of phthalate to non-phthalate plasticizers. Velsicol continues to focus on delivering excellent service, the highest quality products and product stewardship to assure the highest level of customer satisfaction.

Velsiflex® Product Line

Velsiflex 328
Velsiflex 328 is a blend of dipropylene glycol and diethylene glycol dibenzoate in an approximately equal ratio. Velsiflex 328 is primarily known for its exceptional performance in polyvinyl acetate adhesives. It displays excellent wet tack, set times and open time performance. It also improves adhesion to acrylic latex caulks and is a high-solvating PVC plastisol.

Velsiflex 342
Velsiflex 342 is one of the most popular liquid plasticizers. It is a high-solvating plasticizer containing mostly dipropylene glycol dibenzoate. It is used in a wide variety of applications, including caulk, adhesives, resilient flooring, PVC-coated fabrics and artificial-leather cloth. In PVC, it acts as a medium-viscosity high solvator that saves energy and improves process ability. Vinyl applications using Velsiflex 342 have excellent resistance to extraction from solvents and oils. It also works with vinyl to make it UV – light-degradation resistant and stain resistant.

Velsiflex 342 S
Velsiflex 342 S is a blend of dipropylene glycol dibenzoate and other benzoate esters. It is a lower moisture / lower hydroxyl plasticizer. It has been widely used in 2K polyurethane systems to reduce cure interface, which also provides better rebound, improved tear strength and reduced swell with solvents. It is also used in many polysulfide sealant applications and has proven to be a very efficient ester from a softening agent perspective.

Velsiflex 320
Velsiflex 320 is a proprietary blend of benzoate esters resulting in a high-solvating plasticizer. It can be formulated for vinyl alone or in blends of plastisols as well as to melt compounded vinyl. It is a cost-effective and very economical plasticizer that is well suited for latex adhesives, vinyl flooring and plastisol markets.

Velsiflex 290
Velsiflex 290 is a versatile benzoate plasticizer used in a wide array of sealant applications including acrylic, urethane and polysulfide. This benzoate plasticizer is compatible with PVC, PVA and polyurethane. In PVC Velsiflex 290 is low staining for plastisol ink and flooring applications, and performs well in polyurethane applications with improved elongation, tensile strength and hardness.

Velsiflex 318
Velsiflex 318 is a low VOC benzoate plasticizer developed primarily for use in waterborne adhesives and latex caulks. Velsiflex 318 offers enhanced performance, efficiency and a broad list of food contact approvals. Additional applications include VOC reduction for coatings formulators.

Velsiflex 332
Velsiflex 332 is a mixture of benzoate esters that perform as a high solvating plasticizer. With exceptional performance in PVC, Velsiflex 332 provides lower processing temperatures for various plastisol applications from flooring to sealants. In adhesives and caulks Velsiflex 332 provides excellent wet tack, set and open times, as well as improved adhesion properties.

Velsiflex 314
Velsiflex 314 is the original benzoate plasticizer with excellent solvating properties for PVC Plastisols and flexible PVC applications. Velsiflex 314 is a fast-fusing plasticizer that allows formulators to process at lower temperatures and offer lower volatility for today’s challenging markets.

Versatile, High-Solvating Plasticizer for Increased Performance

Velsiflex products are used in a number of applications, including adhesive, sealants, caulk, coatings, inks, plastisol and various flexible PVC uses. Plasticizers for polyurethanes are especially designed to have low moisture and 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. Velsicol prides itself in its strong participation in urethane plasticizer applications as they are highly demanding and precise in their tolerance. As a vinyl plasticizer, Velsiflex has the solvating power that affords ample formulating latitude for optimized PVC formulations. Typical plastisol applications include calendaring, flooring or automotive plastisol sealants.
Velsiflex plasticizers are high performance plasticizers. They are polar and monomeric in nature. In most cases, they provide superior performance compared to other plasticizers as it relates to polymer compatibility, efficiency and desired softness. Overall permanence characteristics which account for these dibenzoate plasticizers to remain within the polymer matrix are also quite desirable. Velsiflex plasticizers are low to medium viscosity fluid esters compatible with a wide range of polymer systems.
