Phthalates Analysis - Polymer Solutions
We have analyzed phthalate plasticizers, and various other types of plasticizers, for many different types of products. The following are examples of products on which we have conducted phthalates analysis: PVC Pipe Children’s toys Medical products Vinyl-coated fabrics Plastic tubing Electrical cables and wires Related Services Additives Analysis
Plasticizer Analysis - Polymer Solutions
The sample size required for plasticizer analysis is 1 to 5 grams. The highly sensitive GC-MS method can provide analysis of plasticizer that is an intentional ingredient, usually in the 1 to 30 percent range, or detect trace amounts that result from contamination or other sources.

Their viscosity–temperature curve is very flat. These plasticizers with special good resistance to low temperatures are used whenever a plasticized polymer is required to have high flexibility even at sub-zero temperatures. Typical low temperature plasticizers include Adimoll adipates, Uniplex sebacates and Disflamoll TOF. Compatibility

The elastomer requires antioxidants, anti-ozonants, fungicides, plasticizers, tackifiers and flame-retardants as the occasion and severity of the application demands. It can be cured with sulfur or peroxide systems. High ACN polymers require high polarity plasticizers, low ACN polymers require low polarity plasticizers.

Polymer Solutions: Solvents and Solubility Parameters Various applications require the selection of a polymer-sol-vent or polymer-plasticizer system. Dissolving a polymer is unlike dissolving low molecular weight compounds because of the vastly different dimensions of solvent and polymer mol-ecules. Dissolution is often a slow process. While
- Which solid-state plasticizers are used in a chemistry study?
- Solubility parameters, thermal analysis, and rheological evaluation were used as assessment tools. Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers.
- What is a solid state plasticizer?
- Based on comparable solubility parameters, stearic acid, glyceryl behenate, and polyethylene glycol 8000 were selected as solid-state plasticizers. Binary and ternary physical mixtures were evaluated as a function of plasticizer concentration for thermal and rheological behavior.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- Are plasticizers miscible with API and polymer?
- Based on the solubility parameter, plasticizers such as SA, GB, and PEG showed Δδ (API) and Δδ (polymer) < 7 MPa ½, and they are likely to be miscible with the API and polymer. These plasticizers are expected to form a one-phase system with the INM-EPO mixture.
- What plasticizers are used in hot-melt extruded systems?
- Although commonly used pharmaceutical plasticizers such as triacetin, 4 citrate esters, 2, 5 and lower molecular weight polyethylene glycols 2, 3, 4 have been investigated in hot-melt extruded systems, almost all of them are liquid.
