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.
Eastman Plasticizers for Adhesives
Admex 6995 is a medium molecular weight, light colored, polymeric adipate with a mild ester odor. Benzoflex 9-88 is a high solvating benzoate ester plasticizer that can be used in a wide variety of polymer systems and applications. Its diverse uses include resilient flooring, adhesives, caulks, and sealants.
Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
PVC Plasticizers and Stabilizers Following Safer ...
Also, Galata’s Drapex Alpha bio-based plasticizers exhibit 7-20% greater plasticizing efficiency versus traditional DOTP and DINCH plasticizer competitors. Finally, both the solid and liquid Mark series stabilizers are approved for certain food-contact applications used in the United States.
Selection of Solid-State Plasticizers as Processing Aids for Hot-Melt
The objective of the study was to select solid-state plasticizers for hot-melt extrusion (HME) process. The physical and mechanical properties of plasticizers, in selected binary (polymer:plasticizer) and ternary (active pharmaceutical ingredient:polymer:plasticizer) systems, were evaluated to asses
- 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.
- 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.
- How to select solid-state plasticizer?
- The selection of solid-state plasticizer should include miscibility of plasticizer in polymer as well as API and its effect on T g and η 0 of the final system. It can be summarized that when components are miscible, different techniques will lead to the consistent plasticization effect prediction.
- 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.
- Are plasticizers effective as processing aids for HME process?
- 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.
- Which reagents are used in solid-state plasticizers?
- Stearic acid (SA) (Mallinckrodt) glyceryl behenate (GB) (Gattefossé, Saint-Priest, France), and polyethylene glycol (PEG) 8000 (Dow-Union Carbide) were selected as solid-state plasticizers to be investigated. All other reagents were of analytical grade.
