Notes: 1) The testing method and index for fluidity are
determined by supplier and user. If there's no
special demand, our factory use rasching
method.
2)
Impact Strength is tested on the samples with
gap.
3)
The blazing bar leaves sample after 3 minutes,
there should not be any flame on sample within
30 seconds.
4)
For technical properties of injection materials,
please refer to relative index of different
types and models.

Notes:
May not be pre-heated before moulding, but
should be degased one or twice. For those above
grade D151, it is suggested pre-heating is a
necessary procedure.
The
moulding condition can be adjusted according to
actual size, thickness, usage of products and
different moulding equipment. In principle, the
quality of finished products can not be
decreased. |
