Dibenzoate Plasticizer Technology
Dibenzoate Plasticizer Technology for Sealants Source Dibenzoate plasticizers are widely utilized in latex caulks because they are compatible with the polymers used in that application. Dibenzoates are also known to be used in the polymer side of two-part insulating glass polysulfide sealants.
Plasticizers - ASTM International
Plasticizers are primarily employed in heavy gage coatings and/or when improved toughness is required for industrial, automotive, and appliance applications. Plasticizers function by reducing the glass transition temperature of the resin to a point below its application temperature.

ASTM D3465-14 March 1, 2014 Standard Test Method for Purity of Monomeric Plasticizers by Gas Chromatography 1.1 This gas chromatographic test method covers a procedure for extending the range of purity determination of monomeric plasticizers beyond that now determined by other methods. Due to the need to... ASTM D3465-00 (2007)e1 November 1, 2007
New standard test method to identify plasticizers | Food
On June 6, 2013 the developer of international voluntary consensus standards ASTM International released a new standard test to determine low level migration of phthalates. The method aims to ensure compliance with the U.S. Consumer Product Safety Improvement Act (CPIA) of 2008, Section 108, which prohibits certain products, including toys, from containing 6 phthalates. The

- What is a plasticizer used for?
- Plasticizers are primarily employed in heavy gage coatings and/or when improved toughness is required for industrial, automotive, and appliance applications. Plasticizers function by reducing the glass transition temperature of the resin to a point below its application temperature.
- How many high boiling fluids are a plasticizer?
- Several thousand high boiling fluids are potential plasticizers for coatings applications. The choice of plasticizer is dependent on compatibility with the resin in use, cost, and other desired attributes. Plasticizers may be classified by both chemical structure and performance characteristics, as shown in Table 1 .
- What color standards are used for plasticizers?
- cken, PA 19428-2959. United States1D1992 − 91 (2013)9. Color9.1 For clear light colored plasticizers, the APHA platinum-cobalt color standards may be used as described in Test Method D1209, but for darker or ore oily plasticizers, the Gardner color standards are n ces ary. The Gardner
- What are the characteristics of a plasticizer?
- Typical plasticizers are liquid esters of molecular weight between about 200 to 800, with specific gravities between 0.75 and 1.35 at 20/20°C, viscosities between 50 to 450 cSt, vapor pressure of less than 3.0 mm of mercury at 200°C, and flash points greater than 120°C (248°F).
- How do plasticizers affect morphological properties?
- Plasticizers fundamentally reduce van der Waals forces between polymer-polymer molecules in the amorphous regions and do not penetrate crystallites [1–3]. The plasticized morphological phase is then of a different nature than that of the neat polymer and has unique mechanical properties.
- How are plasticizers delivered?
- Methods for the isolation, identification, and quantitative determinations of these plasticizers are also included. Domestic orders are delivered via United Parcel Service (UPS) or United States Postal Service (USPS). Transit times average 3 to 5 business days. Please be aware that UPS will not deliver packages to Post Office Boxes.
