| PANEL ROVING
990 Panel Roving
990 Panel roving is manufactured from E Glass and gathered without mechanical
twist and wound into a cylindrical package. 990 Panel Roving has a silane sizing system designed to be
highly compatible with polyester resins that are used with continuous production equipment
for the manufacture of translucent sheeting as well as with filled resin systems. Typical
refractive index for 990 panel rovings is 1,5569.

Packaging
990 Panel roving is individually wrapped in a Polythene sleeve and packed into a cardboard carton.
 Application
990
Panel roving can
be readily chopped into lengths between 25 mm and 75 mm. The soft nature of 990
Panel roving means
that the chopping equipment to be used must be suitable for this type of roving.
990 Panel roving sizing system contains a suitable anti-stat agent to facilitate multiroving feeding from
suitable creels. 990 Panel rovings are not suitable for choppergun applications.
Approval
990 Panel roving is manufactured to the requirements of the South African Bureau of Standards
specification SABS 1446-1988.
Storage
It is recommended that fibreglass be kept at a minimum temperature not exceeding 25°C
and a relative humidity not exceeding 65%.
Owens Corning South Africa reserves the right to change this specification without notice. |
