Fact.MR has announced the addition of the "Plasticizer Concrete Admixtures Market Forecast, Trend Analysis & Competition Tracking - Global Market insights 2018 to 2028"report to their offering.
Summary: Plasticizer concrete admixtures are powders or liquids added before or during the mixing of concrete.
An alternative PVC plasticizer launched by PolyOne Corp., Avon Lake, Ohio, reportedly has performance equivalent to industry workhorse 810TM linear trimellitate plasticizer and is formulated for wire/cable and automotive slush molding.
However, the high plasticizer migration from plasticized PLA films limits its use in the food packaging and other consumer products, because it undermines physical properties, especially poor storage stability and low barrier to gas [17, 18], water vapor [19], and organic compounds [20, 21].
To find a plasticizer option that performs similarly to DEHP, the material many device designers and OEMs currently use for tubing, device designers are turning to alternate non-phthalate plasticizers to satisfy regulatory requirements and customer preferences.
With increasing pressure on device manufacturers to move away from DEHP in PVC, OEMs are seeking a plasticizer option that performs similarly without the related, potential health concerns.
* Eastman Chemical Company has announced another addition to its non-phthalate plasticizer portfolio with Eastman Versafix plasticizer, which is designed specifically for water-based adhesives.
One of the major criteria in selecting a plasticizer is compatibility with the resin to which it is added.
In addition, Eastman proposes to modify and restart the currently idled plasticizer manufacturing facility to produce non-phthalate plasticizers, including Eastman 168 non-phthalate plasticizers to serve the growing market demand for non-phthalate alternatives.
The influence of the glass transition temperature and the mechanical and anticorrosion properties of factors such as the amount of plasticizer added to an epoxy primer were investigated by DSC (differential scanning calorimeter), DMA (dynamic mechanical analysis), stress-strain tests, salt fog spray tests, accelerated tests, and electrochemical tests.
DEHP is the primary phthalate plasticizer for such vinyl medical devices.
