Ultramid® A 225F NATURAL
聚酰胺 66 （尼龙66）PA66
德国巴斯夫-BASF Corporation
Ultramid® A 225F Natural is an unfilled polyamide 66, medium viscosity, for injection moulding, with a special crystallizing agent, for very fast cycles. This grade offers a good combination between primary properties of the unreinforced polyamide 66 and processing properties leading to increased productivity. These performances are associated with excellent dimensional stability, and excellent filling qualities. The UL94 V2 rating at 0.4mm makes that the product is particularly used in electrical applications.

| 注射说明 The material is supplied in airtight bags, ready for use. In case that the virgin material has absorbed moisture, it must be dried with a dehumidified air drying equipment, dew point mini -20℃. Recommended time 2-4h Injection Advice: For unfilled polyamides, BASF SE recommends the use of high alloy steel with a low chromium content. For example: X38CrMoV5-1 (EN Norm) - 1.2367 /1.2343 (DIN Norm). In the case of high requirements on surface quality a mould temperature of up to 120℃ can be considered. The processing parameters like processing temperatures are a recommendation and can be adjusted in function of injection machine size, part geometry / design |
