Key Properties of VersaMerTM PHA
Irregular pieces, pellets, latex.
VersaMer PHAs typically have a density of 1.02±0.01 g/cm3.
VersaMer PHAs are soluble in most solvents that can dissolve PHB or PHBV. They are also soluble or partially soluble in many solvents that are non-solvents to PHBV. The following solvents have been tested in our laboratory with all types of VersaMer PHA we currently produce.
VersaMer PHAs are isotactic stereoregular thermoplastic elastomers of 100% R configuration.
VersaMer PHAs absorb 0.15% (weight) moisture in an humid environment, and 0.25% moisture when immersed in water completely.
VersaMer PHAs start thermal degradation at 240oC (determined by Thermal gravimetric analysis).
VersaMer PHAs have Tg between -45oC and -35oC.
VersaMer PHAs have peak Tm between 45oC and 65oC, depending on monomer compositions.
VersaMer PHAs have weigth average molecular weight between 100,000 and 150,000, and Polydispersity Index between 1.75 and 1.83, depending on monomer compositions.
VersaMer PHAs have elongation-at-break value between 1200% and 1400%, tensile-stress-at-break value between 7 and 16 MPa, and Young's Modulus value between 2 and 12 MPa, depending on monomer compositions.
When heated above their melting temperature, VersaMer PHAs are low viscosity materials.
VersaMer PHAs can be prepared into latex with particle size from 100nm to 500nm, depending on monomer compositions.
