Back pressure: LowInjection pressure: HighPBT materials are hygroscopic and very sensitive to moisture content during processing. Unlike many other materials, excessive moisture may not give rise to the appearance of splash marks on the surface of mouldings, but hydrolytic degradation of the melt can lead to significant impairment of properties, characterised most noticeably by embrittlement of the mouldings and reduced melt viscosity. Adequate pre-drying is therefore essential.Drying should ideally be carried out in a vacuum oven or a dehumidified air drier. The recommended drying time for dehumidified air dryers is 4 hours at 120°C. Drying times may need to be extended if the material has become very wet. |

1 . | Mould shrinkage is significantly influenced by many factors including wall thickness, gating, component shape and moulding conditions.The range values stated were determined from specimen bar mouldings of 1.5mm to 4mm wall thickness. They are provided as a guide for comparison purposes only and no guarantee should be inferred from their inclusion. (Specimens measured in the dry state, 24 hours after moulding). |
