Technical Details & Test Data
- VISCOSITY NUMBER - RESIDENCE TIME
Unnecessarily high melt temperatures and excessively long residence times of the melt in the cylinder and the hot runner can bring about molecular degradation. The figure shows an example (Ultradur® B4520) illustrating how the viscosity number acts as a measure of the molecular weight as a function of the melt temperature and residence time. Based on experience material degradation of less than 10 % based on the measured viscosity in solution of the granules and the molding is tolerable. In the event of values higher than this the processing and drying parameters should be checked.
Safety & Health
- Product Safety
Ultradur® melts are stable at temperatures up to 280°C and do not give rise to hazards due to molecular degradation or the evolution of gases and vapors.
Like all thermoplastic polymers, however, Ultradur decomposes on exposure to excessive thermal stresses, e.g. when it is overheated or as a result of cleaning by burning off. At temperatures of > 290°C can be emitted: carbon monoxide, tetrahydrofuran.Under special fire conditions traces of other toxic substances are possible.
Formation of further decomposition and oxidation products depends upon the fire conditions. When Ultradur® is properly processed and there is adequate suction at the die no risks to health are to be expected.Further safety information see safety data sheet of individual product.
