Oxymethylene copolymerizate molding compositions with reduced formaldehyde emission in the thermoplastic processing |
摘要 |
The formaldehyde emission in the thermoplastic processing of antioxidant containing oxymethylene copolymer molding compositions is reduced considerably if these molding compositions additionally contain on the surface or homogeneously mixed in a specifically defined formaldehyde binding material which contains in the molecule at least two 4,6-diamino-1,3,5-triazin-2-yl groups. In this way there are avoided deposits on the die and odor annoyance.
