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.
Plasticizer - an overview | ScienceDirect Topics
Plasticizers are low molecular weight substances added to a polymer solution to promote its plasticity and flexibility. Therefore, the plasticizers make the polymer solution more suitable for the application of film coating. There should be chemical similarities between the polymers and its plasticizers.
Specialty Plasticizers for Rubber/Elastomers | Hallstar
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.
Selection of Solid-State Plasticizers as Processing Aids
The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to assess their effectiveness as processing aids for HME process.
- 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.
- 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.
- 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.
- Do plasticizers increase polymers' flexibility at room temperature?
- Disentanglement of CA chains is favored at higher plasticizer content under extensional flow, yielding lower melt strength and higher melt extensibility . These observations confirm that plasticizers increase polymers' flexibility at room temperature and can be used as processing aids.
- 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.
- Why does a polymer dissolve like a plasticizer?
- Dissolution occurs when polymer and plasticizer have similar polarities, which is well described by the rule “like dissolves alike.” It means that the energy of interaction between heterogeneous molecules of solution components is as strong as the energy of interaction between homologous molecules .
