Four Major Development Trendsof Chemical New Materials
                             By Hua Xin
According to the projection of experts, the development of chemical new
materials will have the following four major trends in  the  next  few
years: (1) The production units will be large-sized with economic scale.
(2) The production of monomers and resins will be  concentrated,   the
  production  of  products  will  be  moderately  dispersed  and   deep
processing will be more emphasized. (3) Development priority  will  be
on organosilicon materials,   organofluorine  materials,   engineering
plastics and alloys, separation membranes and separation technologies.
In organosilicon materials, a 50 000 - 60 000 t/a monomer unit  and  2
or 3 product and deep-processing bases will be constructed. The second
phase and the third phase expansion will  be  followed  to  raise  the
capacity of organosilicon monomers to 150 000 - 180 000  t/a  .     In
organofluorine  materials ,  a 3 000 t/a  Teflon unit,   a  1 000  t/a
PVDF unit and a 1 000 t/a fluorine rubber unit will be constructed. In
  engineering  plastics  and  alloys,   a  40  000  -    50   000   t/a
polyformaldehyde  resin  unit, a 20 000 -  50  000  t/a  polycarbonate
unit and associated deep-processing units  will  be  constructed.   In
separation membranes and separation technologies, a 30 000  m2/a  unit
  of    ionic    membranes  used  in  the   chlor-  alkali   industry,
ultrafiltration and  microfiltration  membrane  units  and  separation
membrane equipment units will be constructed. Special-fiber  and  high
-performance composite materials and special gases will be developed. (4)
  Scientific  research  of  chemical  new  materials  will  be  further
integrated with production. It is expected that  by  the  end  of  the
century the consumption  will  reach  8  000  tons  for  organosilicon
monomers, around 7 000 tons for  teflon  and  over  80  000  tons  for
engineering plastics. The sales volume of chemical  new  materials  in
China will be more than 10 billion yuan at the end of the century.
