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.
