shocks for many days! How does Tuesday choose direction? To tellyou the truth, my friends, the market has not changed our May 25review phase of the market before. We will never change our views.As for why the market will continue along 3585 shocks? Can themarket break through on Tuesday? In this regard, we still urged ourfriends to be clear about the current market fundamentals, policy,technical aspects, the main force to continue to control the marketin what situation? If it's confusing, if it's confusing,. In thesecond half of 2021, nine times out of ten, you're
高刚性PA66 FR52G30NH-BK337美国杜邦
良好的耐高温性能
高熔点范围，高达 3l0°C (590°F)
o 高玻璃转化温度，干态，80oC (176°F) 至 141°C (286°F)
o 热膨胀系数低，增强规格等。
针对以下的耐化学性：
o 发动机变速箱油和变压器油
o Glycols
注射压力：通常在750~1250bar，取决于材料和产品设计。
注射速度：高速（对于增强型材料应稍低一些）。
流道和浇口：由于PA66的凝固时间很短，浇口的位置非常重要。浇口孔径不要小于0.5*t（这里t为塑件厚度）。如果使用热流道，浇口尺寸应比使用常规流道小一些，因为热流道能够帮助阻止材料过早凝固。如果用潜入式浇口，浇口的小直径应当是0.75mm。PA66塑料应用PA66是PA系列中机械强度高、应用广的品种，因其结晶度高，故其刚性、耐热性都较高。
