DESCRIPTION:
Diallyl phthalate is a clear pale-yellow liquid.
Diallyl phthalate is odorless.
Diallyl phthalate is a thermosetting resin with a lot of excellent physical properties such as electrical insulation properties, heat resistance, water resistance, chemical resistance, and molding.
In addition to being used in inks and construction materials, this material addresses a wide range of needs in different industries such as electronic and electrical components which require high quality level.
Because of quick-drying, Diallyl phthalate is used in organic solvent free UV printing inks.
Diallyl phthalate is also adopted electric and electronic parts for high durability in tough high temperature and high voltage environments.
Diallyl phthalate is also used in environmentally friendly decorative laminate construction material which does not contain volatile organic compounds (VOC).
Although different values for vapour pressure of diallyl phthalate are given ranging from 0.0049 to 0.155 Pa, the value of 0.0213 Pa is considered as most reliable.
The reported water solubility of diallyl phthalate is in the range of 45 to 182 mg/L.
The key value of 148 mg/L was selected from the most reliable study.
Production of Diallyl phthalate during 2002 is estimated at 4400 tonnes worldwide.
Annual production at the two manufacturing sites in Japan is estimated at 3900 tonnes.
Diallyl phthalate is produced either by the esterification reaction between allyl alcohol and phthalic anhydride, or by the condensation between allyl chloride and disodium phthalate.
Diallyl phthalate functions as a crosslinking agent. The functionality is ascribed to the two highly reactive allyl groups in the molecule.
The allyl groups are able to react with other unsaturated organic chemicals to form C-C covalent bonds.
Diallyl phthalate also functions as a plasticizer. However, unlike other phthalate esters, such as di-butyl phthalate (DBP), di-(2-ethylhexyl) phthalate (DEHP), etc.
Diallyl phthalate is used as a reactive plasticizer.
Diallyl phthalate is added to polymer and prepolymer systems in order to make them softer and more easily moulded during the curing process and then it binds covalently into the polymer matrix to produce rigid.
The other phthalate esters, such as DBP and DEHP are normally added to the polymer in order to make the end products softer or more flexible.
Due to their lack of functionality, these other phthalate esters do not bind chemically into the polymer matrix, and, therefore, there is the potential for them to leach out.
Whereas other phthalate esters are used at up to levels greater than 50% to plasticize final products, no use of DAP where it functions to plasticize the final product is known.
Diallyl phthalate is also used as a crosslinking agent during the manufacture of other polymers such as polyvinyl chloride (PVC), unsaturated polyesters (UP), etc.
Such polymers are used for finished consumer products such as window frames, insulating varnish for coil and wire, and sheet moulded compound for ship body.
Diallyl phthalate added to such polymers reacts, in the similar way to the DAP prepolymer, to be incorporated via covalent bonds into the polymer matrix of the finished consumer products.
During the chemical process, Diallyl phthalate functions as an agent for improving flowability and viscosity of compound mixture.
Diallyl phthalate is consumed during the process and gives hardness to the finished consumer products.
Diallyl phthalates are thermosetting ester resins produced by the reaction of allyl alcohol with ortho-phthalic anhydride and meta-phthalic anhydride, respectively.
The cured resins have excellent electrical insulating properties including high insulation resistance and low electrical losses, even when subjected to to high heat and humidity over long periods of time.
They also have excellent dimensional stability and do not warp in high-heat applications.
Furthermore, they have low moisture absorption, excellent weathering properties, and good chemical resistance to many chemicals and solvents including aliphatic hydrocarbons, oils, alcohols, acids, and alkalis.
Diallyl phthalate and DAIP prepolymers are mainly used as molding resins for electrical and electronic parts such as switches, connectors, control panels, circuit breakers, terminal boards, resistors, and insulators.
Other (potential) applications include laminates, prepregs, headlight lamp reflectors, bathtubs, sinks, appliance handles and control knobs.
Diallyl phthalate is used in the production of thermosetting molding powders, casting resins and laminates.
This is the material of choice for critical, high-performance military and commercial electrical components where long-term reliability is demanded due to its ability to retain its superior insulating properties, even when subjected to extreme environmental conditions of high heat and high humidity over long time periods.
Additionally, DAP compounds will resist dimensional change in high-heat soldering environments where competitive materials may warp.
Diallyl phthalate is a filled thermoset resin recommended for mounting moderately hard materials and provides good edge retention.
Diallyl phthalate is available as either glass or mineral filled.
Diallyl phthalate is used as a plasticiser and carrier for adding catalysts and pigments to polyesters.
Diallyl phthalate is used in electrical parts, laminating compounds, and impregnation of metal castings.
Diallyl phthalate is also found in rubber compounds, epoxy formulations, and polyurethane foams.
Diallyl phthalate is imported for use as a primary plasticiser for electrical insulation materials, flexible fibreglass topcoat laminates, adhesives and injection moulding materials.
Diallyl phthalate is distributed also to various institutions and laboratories for analytical, pharmaceutical and biotechnological research.
Diallyl phthalate is a phthalate ester.
Diallyl phthalates are esters of phthalic acid and are mainly used as plasticizers, primarily used to soften polyvinyl chloride.
They are found in a number of products, including glues, building materials, personal care products, detergents and surfactants, packaging, children's toys, paints, pharmaceuticals, food products, and textiles.
Diallyl phthalate belongs to the class of organic compounds known as benzoic acid esters.
These are ester derivatives of benzoic acid. Based on a literature review a significant number of articles have been published on Diallyl phthalate.
Diallyl phthalate has been identified in human blood.
Diallyl phthalate is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives.
Technically Diallyl phthalate is part of the human exposome.
The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health.
Diallyl phthalates have high hardness and superior chemical resistance.
They are excellent for applications where edge retention is a concern.
Copper diallyl phthalate is electrically conductive for SEM and spectrometer applications.
Diallyl phthalate is a widely used crosslinking agent for unsaturated polyesters.
