Title:
MOLDED RESIN CONTAINING FILLER AND GLASS
Document Type and Number:
WIPO Patent Application WO/2011/016127
Kind Code:
A1
Abstract:
A molded resin containing a filler and glass is provided which has no skin layer in the surface and suffers no deformation such as sink or warpage.  Even when the amount of the filler incorporated is small, the filler can sufficiently perform the same function as the function of the filler incorporated in amounts conventionally used.  The resin is one member selected from a group consisting of polyethylene resins, polypropylene resins, polyethylene terephthalate resins, and polyamide resins.  The glass is solid spherical glass beads having an average particle diameter of 10-40 µm.  The proportion of the solid spherical glass beads is in the range of 40-70 wt.%.  An examination by laser Raman spectroscopy shows that the glass-containing molded resin has no skin layer in the surface thereof.  The solid spherical glass and the filler are present in the surface of the molded resin.  The filler is hence capable of performing the function thereof.
