尼龙是应用最广泛、用途最广泛的热塑性树脂之一。它的物理特性与价格的结合使得它成为许多应用程序的首选。尼龙在替代金属、黄铜、青铜、铝和橡胶等其他材料方面有着一贯的历史。在更换机械中的金属齿轮时,尼龙具有降低噪音、减少润滑和延长齿轮寿命的能力,因此具有优势。Tecamid MDS是一种挤塑钼填充尼龙6/6,呈灰色。二硫化钼颗粒的加入提高了表面润滑性和对未填充尼龙的耐磨性。在需要高润滑性的应用中,这种材料可能是很好的候选材料。除了更大的润滑性外,还有许多其他的性能增强。Tecamid MDS增强了性能,使其成为替代机械金属的理想材料。它可以提高许多运动部件的寿命,并提供噪音降低的好处,需要较少的润滑。一种非常稳定的化合物,有许多工业用途。低表面摩擦增加表面硬度增加耐热性提高拉伸性能提高尺寸稳定性 Nylon is one of the most widely used and versatile thermoplastic resins. Its combination of physical properties versus its price makes it a favorite choice for numerous applications. Nylon has a consistent history of replacing other materials including: metal, brass, bronze, aluminum, and rubber. In replacing metal gears in machinery, nylon can be advantageous because of its ability to reduce noise, use less lubrication and increase gear life. TECAMID® MDS is an extruded "moly" filled nylon 6/6, which is gray in color. The addition of particles of molybdenum disulfide enhances the surface lubricity and wear resistance over unfilled nylon. In applications requiring high lubricity, this material may be a good candidate. In addition to the greater lubricity there are many additional property enhancementsthat occur. TECAMID® MDS has enhanced properties which make it an ideal material to replace metals in machinery. It can increase the life of many moving parts as well as provide a noise reduction benefit and requires less lubrication. A very stable compound with many industrial applications. Low surface friction Increased surface hardness Increased heat resistance Higher tensile properties Improved dimensional stability |

塑料消费旺季降临 近强远弱照旧
2017-09-25 塑料消费旺季来临,下游农膜开工率持续提升,通常这种趋势会延续至10月底或11月初,在此阶段,塑料需求将会明显改善。二季度装置集中检修使得石化库存快速消化,近期一直维持在低位,那么在消费旺季,石化库存很难积累,甚至有进一步去库存的可能,因此低库存现状短期难以改变,这对塑料价格将会产生有力支撑。 然而,塑料产量已经恢复至高位,利润丰厚支撑装置高负荷运行,预计三四季度塑料产量都将在较高水平。进口方面,因贸易盈利可观进口量也有大量增加的可能,一旦进 |
