近日监测小组公开最新参数:今日行业协会披露行业新成果,TPU色母与PA6色母的通用性探讨

在塑料制品的生产过程中，色母是不可或缺的添加剂，它不仅能够赋予塑料产品丰富的色彩，还能改善塑料的加工性能。TPU色母和PA6色母作为市场上常见的两种色母，它们在性能和用途上各有特点。那么，TPU色母与PA6色母能否通用呢？本文将对此进行探讨。 首先，我们来了解一下TPU色母和PA6色母的基本特性。 TPU色母，全称为热塑性聚氨酯色母，是一种具有优异的耐磨性、耐油性、耐低温性和柔韧性的色母。它广泛应用于鞋材、电缆、管材、玩具等领域。TPU色母的加工温度一般在150℃-180℃之间。 PA6色母，全称为聚酰胺6色母，是一种具有高强度、高耐磨性、耐化学性和耐热性的色母。它广泛应用于汽车、电子、家电、纺织等领域。PA6色母的加工温度一般在210℃-250℃之间。 从上述特性可以看出，TPU色母和PA6色母在加工温度、性能和用途上存在一定的差异。那么，它们能否通用呢？ 1. 加工温度不同：由于TPU色母和PA6色母的加工温度存在较大差异，因此在使用过程中，不能直接将TPU色母用于PA6塑料的加工，反之亦然。否则，可能会导致塑料产品出现熔融、变形等问题。 2. 性能差异：TPU色母和PA6色母在耐磨性、耐油性、耐低温性等方面存在差异。如果将TPU色母用于PA6塑料，可能会影响塑料产品的性能。同样，将PA6色母用于TPU塑料也可能导致产品性能下降。 3. 用途不同：TPU色母和PA6色母在应用领域上存在差异。例如，TPU色母适用于鞋材、电缆等领域，而PA6色母适用于汽车、电子等领域。因此，在选用色母时，应根据塑料产品的用途和性能要求进行选择。 然而，在某些特定情况下，TPU色母和PA6色母可以相互替代。以下是一些可能的情况： 1. 在某些特殊场合，如加工温度接近的情况下，可以考虑将TPU色母用于PA6塑料的加工，但需注意观察塑料产品的性能变化。 2. 在某些特殊用途的塑料产品中，如果对性能要求不高，可以考虑将TPU色母或PA6色母用于替代，但需确保塑料产品的质量。 总之，TPU色母与PA6色母在加工温度、性能和用途上存在差异，一般情况下不能通用。但在特定情况下，可以考虑相互替代。在实际应用中，应根据塑料产品的性能要求、加工条件和用途，合理选择合适的色母，以确保产品质量。

TMTPOST --   Chinese telecommunications giant Huawei unveiled a sweeping expansion of its artificial intelligence computing ambitions on Thursday, announcing new supercomputing systems powered by its in-house Ascend chips. The move signals escalating competition with U.S. chipmaker Nvidia, the global leader in AI processors.AI-generated imageAt its annual Huawei Connect conference in Shanghai, the company introduced the forthcoming "Atlas 950 SuperCluster," which it said will begin rolling out as early as next year. The announcement underscores Huawei ’ s determination to challenge U.S. dominance in advanced AI hardware despite Washington ’ s tightening export controls on semiconductors."The competition has undeniably arrived and is gaining momentum," an Nvidia spokesperson said. "Customers will choose the best technology stack for running the world ’ s most popular commercial applications and open-source models."U.S. restrictions have cut China off from the most advanced chips needed to train large-scale AI models, forcing Chinese firms to rely on domestically developed processors or stockpiles of older foreign components. Huawei, long targeted by U.S. sanctions, has turned to large-scale clustering of its less powerful but increasingly refined Ascend processors. By combining vast numbers of these chips in interconnected networks, the company aims to match or surpass the performance of systems built on Nvidia ’ s hardware.Huawei said it plans to release three new versions of its Ascend chips through 2028, pledging to double computing power with each iteration. At the base level, its new Atlas 950 supernode will connect 8,192 Ascend chips. A full Atlas 950 SuperCluster would integrate more than 500,000 chips.A future upgrade, the Atlas 960 system slated for 2027, is projected to support nearly 15,500 chips per node and scale to more than 1 million Ascend processors across a full supercluster. Huawei claimed these would represent the world ’ s most powerful AI systems by raw computing power.Huawei did not shy away from comparisons with its American rival. Eric Xu, the company ’ s vice chairman and rotating chairman, said the Atlas 950 supernode would deliver 6.7 times more computing power than Nvidia ’ s upcoming NVL144 system. He went further, predicting Huawei would "be ahead on all fronts" compared with Nvidia ’ s 2027 offering — and claimed the Atlas 950 SuperCluster would even exceed the computing capacity of Elon Musk ’ s xAI Colossus project.While independent verification of Huawei ’ s claims is limited, industry experts said the company ’ s ambition is clear."Huawei ’ s announcement on its computing breakthrough is well timed with recent increasing emphasis by the Chinese government on self-reliance on China ’ s own chip technologies," said George Chen, partner and co-chair of the digital practice at The Asia Group. While noting that Huawei might be overstating its technical edge, he added, "the ambition to be a world AI leader cannot be underestimated."Research from SemiAnalysis earlier this year found that Huawei ’ s CloudMatrix system outperformed Nvidia ’ s equivalent despite each Ascend processor offering only about one-third the power of an Nvidia chip. The advantage came from scale: Huawei deployed roughly five times as many chips in its clusters."Computing power has and will continue to be the key for AI," Xu emphasized during his keynote speech in Shanghai.Huawei ’ s new announcements build on earlier efforts. Two years ago, it introduced the Atlas 900 SuperCluster, which it still markets with "thousands" of Ascend chips. On Thursday, the company said it had already deployed more than 300 Atlas 900 A3 supernodes to over 20 clients across telecoms, manufacturing, and other sectors.This momentum reflects a broader push within China to substitute foreign technology with homegrown alternatives. Beijing has increasingly pressed domestic firms to use local suppliers and invest in national semiconductor capabilities. Huawei ’ s breakthroughs are likely to be touted as proof of progress in these efforts.Huawei ’ s offensive comes as Nvidia faces growing headwinds in China, once one of its most important markets. Earlier this week, China extended an antitrust probe into the U.S. company over alleged monopolistic practices. On Wednesday, Nvidia ’ s shares fell more than 2% after the Financial Times reported that Beijing had ordered Chinese tech giants to halt testing and purchases of the RTX Pro 6000D, one of Nvidia ’ s new AI-focused chips.Nvidia Chief Executive Jensen Huang expressed frustration over the developments. "I am disappointed to hear this news," he told reporters, while reiterating that Huawei represents a "formidable" competitor.The geopolitical context adds another layer of complexity. The U.S. and China concluded trade talks in Spain this week that reportedly included discussions over the fate of TikTok, the video app owned by Beijing-based ByteDance. But technology co
