Wollastonite modified PVC. Acicular wollastonite is a natural-fiber new minerals, or is generally radial
needlelike, noncrystalline water, high melting point, a small hygroscopicity, 1:101:15 aspect ratio can
be achieved, thermal stability , and not scratched the surface advantages can be achieved as long
fiber reinforced resin filler performance. Compared with the base resin can be strengthened 1.95 times
the flexural strength increased 1.47 times. Therefore PVC enhancements, toughening modification, the
development of high strength and high toughness of the PVC, so as to promote the works of this
plastic is of great significance. Although PVC is a large class of highperformance integrated common
plastic, but as rigid PVC productscan not be widely used in structural materials used acicular wollastonite
to fill this polymer, in order to make it fast and low dispersion of the viscosity, which reinforced PVC,
toughening modification, the development of highstrength and high toughness of the PVC good role |
