Dibenzoate Plasticizer Technology for Sealants - ASTM International
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 liquids of molecular weight greater than that of solvents—to limit volatility—but are not solids, such as alloying polymers, etc. It should be noted that cross-linked resinous coatings significantly reduce plasticizer loss due to diffusibility and volatility.
New ASTM Adhesives Standard Will Test PVC Flooring
New ASTM Adhesives Standard Will Test PVC Flooring Materials for Plasticizer Migration A new ASTM International standard will provide a qualitative means to determine the potential effect of plasticizers contained within polyvinylchloride floor covering materials on a specific adhesive.

ASTM International publishes method to ensure compliance with US phthalate migration standard June 28, 2013 Charlotte Wagner Reading time: 1 minute 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.
ASTM D1045 : Standard Test Methods for Sampling and Testing
ASTM D1045, 2025 Edition, August 1, 2025 - Standard Test Methods for Sampling and Testing Plasticizers Used in Plastics. These test methods cover sampling and testing of liquid plasticizers used in compounding of plastics. Acid number, ester content, specific gravity, color, refractive index, and water content are determined.
- 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 .
- Are plasticizers a solid or a liquid?
- Plasticizers are liquids of molecular weight greater than that of solvents—to limit volatility—but are not solids, such as alloying polymers, etc. It should be noted that cross-linked resinous coatings significantly reduce plasticizer loss due to diffusibility and volatility.
- 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 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.
- How do plasticizers work?
- Plasticizers function by reducing the glass transition temperature of the resin to a point below its application temperature. The chemical mechanism of plasticization involves a strong polar association of polymer-plasticizer molecules, but not a chemical reaction between them.
