Testing or identification of Plastics:
The density of unreinforced PPS was 1.4 GCM ˉ³, The guild sinks rapidly in water and slowly in saturated magnesium chloride solution (density is 1.34); The density of PPS containing 40% GF was 1.6 GCM ˉ³. The fiber content can reach 45%. When mineral filler and glass fiber are used together, the total filler content can reach 65% (by weight)
Treatment of plastics and products:
However, heating is good for processing, so all materials should be dried. It is best to dry them in a dehumidifier (175 ℃) at 150 ℃ for 3 hours - even in an ordinary oven for 6 hours Hardness, crystallinity and HDT above 260 ℃
Generally speaking, the hot mold (above 135 ℃) can produce enough crystallinity and excellent surface. However, if the product is not required to be heat-resistant and stable, the cold mold (30-90 ℃) can be used. The HDT of such (low crystallinity) products may only be 230 ℃. The surface of the parts may be poor, It can be dried at 150 ℃ for 3 hours
