PMC Metallic Stearates for Plastics, Product Article - ChemPoint
In plastics, metallic stearates are used as lubrication aids, mold release agents, or acid scavengers due to their high thermal stability properties. Lastly, these polymer stabilizers are used in plastics melt processing to optimize overall production output and produce finished articles with smoother surfaces.
Citroflex Plasticizers for Flexible PVC - ChemPoint
Citroflex is the ideal plasticizer for use in the following plastic applications: Food packaging films and plastics Vinyl resins used in toys Plastic tubes for medical applications and devices Why Choose Citroflex Plasticizers For Your PVC Plastics Non-phthalate Improved heat and light stability
Plasticizers: Types, Uses, Classification, Selection & Regulation
Most common plasticiser chemistries include citrates, benzoates, ortho-phthalates, terephthalates, adipates, azelates, sebacates, and trimellitates. Plasticizers are the most common additives used in the plastics industry. But, selecting the right plasticizer for an application has always been a daunting task.
Long- and short-term stability of plasticized poly(lactic
A single T g in the DSC thermograms was observed for all of the samples that indicated good compatibility between PLA and plasticizers . It can be seen from the DSC curves (Figs. S1–S12) that the single peak seen in melting endotherm of neat PLA (Figs. 1 and 2 ) turned into a bimodal curve in nearly all PLA/PEG systems.
Plasticizers in Paint & Coatings: Uses, Types and Selection
Good stability to heat and ultraviolet light Broad range of compatibility, and Excellent resistance to hydrolysis Di-iso-octyl phthalate (DIOP) DIOP is like DOP, an all-purpose plasticizer for polyvinyl chloride, polyvinyl acetate, rubbers, cellulose plastics, and polyurethane. Di-iso-nonyl phthalate (DINP) & Di-iso-decyl phthalate (DIDP)
- Which plasticizer has the best mechanical properties?
- Of the plasticizers we synthesized, the best film mechanical properties were provided by OC plasticizer, containing primarily propylene glycol monoacetate, but also propylene glycol diacetate, acetic acid and propylene glycol in its mixture.
- Do plasticizers deteriorate the thermal stability of plasticized PVC?
- When plasticized samples were subjected to the same temperature ramp, dramatic differences were observed compared to the above results for the plasticizers alone. Unplasticized PVC was stable up to 212 °C, whereas the addition of plasticizers deteriorated its thermal stability to some extent for every plasticizer studied.
- Which plasticizer is best for chitosan?
- Glycerol and polyethylene glycol were found to be more suitable as plasticizers of chitosan than ethylene and propylene glycol. In addition, chitosan films containing 20 wt% glycerol or polyethylene glycol showed good stability for 5 months.
- What are the chemical properties of plasticizers?
- The chemical properties, such as acid value, iodine value, saponification value, ester value and water content were determinated for the plasticizers and are shown in Table 2. This values provide an additional confirmation for the occurrence of esterification and epoxidation reactions, respectively.
- What are plasticizers used for?
- 1. Introduction For decades, plasticizers have been extensively used with polymers for producing flexible plastics to be used in commodity, engineering and medical applications.
- Can glycerol be used as a plasticizer for chitosan films?
- Suyatma et al. (2005) studied the effects of ethylene glycol, propylene glycol, polyethylene glycol and glycerol on the mechanical and surface properties of chitosan films that were stored for 3 and 20 weeks. Glycerol and polyethylene glycol were found to be more suitable as plasticizers of chitosan than ethylene and propylene glycol.
