Frp & Grp Fiberglass Products By Saphire Polymers

FRP & GRP Fiberglass ProductsWe, Saphire Polymers, manufacture FRP/GRP fiberglass products by
using wet lay up process with match die moulding for double side
finish, single side smooth contact moulding, and PP/PVC lined with
FRP/GRP moulding. We use following procedure for manufacturing these
products
Gel coat made from aerosil/talk powder, chalk
powder mixed with liquid thermosetting plastic called resin which is
applied on the mould depending upon the individual requirements of the
products constituting up to 0.3mm thick of the product.A layer of CSM (chopped strand matt) is laid on the dried gel coat and wetting of the same is done using resin.Subsequent layers of Owen roving or CSM are laid with procedure to build up the thickness of desired level.In case of match die moulding the moulds are matched and excess resin is squeezed with fasteners to lock the moulds.
The
products manufactured by us have advantages like chemically inert to
many of the chemicals, low cost of manufacturing in case of low
volumes, cost per mould constitutes only making an wooden pattern and
maximum of two piece charges, intricate designs can be made without
welding or bonding and density between 1.42 to 2 resulting in high
strength to weight ratio. There are some limitations also which should
be kept in mind like low shelf life of raw materials, high labor
components as each and individual piece has to be made separately
without the use of machines.
