尼龙自1938年问世以来,已成为世界上公认和应用最广泛的工程级热塑性塑料之一。尼龙独特的高强度、高韧性、优异的耐化学性、优异的耐磨损性,使其成为众多行业产品设计的首选材料。当用于更换磨损等级的金属,如黄铜和青铜时,没有其他材料提供延长磨损寿命、重量轻和低制造零件成本尼龙的组合。NYTEF塑料有限公司生产各种类型和库存形状配置的Unipa尼龙库存形状。这些unipa尼龙产品分为6/6型挤压unipa尼龙和6型unipa m铸造尼龙。虽然这两种类型的尼龙非常相似,但应注意的是,这两个等级之间存在性能和可用性差异:Unipa M 6型铸造尼龙:提供更高的耐磨性,可提供更大的杆直径(高达13“直径),可提供更大的板尺寸(高达48”x 96”),NYTEF塑料使用专有尼龙。在铸造工艺上生产出Unipa M尼龙6号坯料形状。这一工艺使得具有非常厚横截面的尼龙棒、板和管状杆件能够经济地生产出来,具有均匀的物理性能和最小的内应力水平。NYTEF塑料公司的Unipa M尼龙6库存形状有多种等级,包括润滑、热稳定和纤维增强产品。Unipa M尼龙6材料有各种圆杆、厚规格板和管状杆尺寸。 Since its introduction in 1938, Nylon has become one of the world's most widely recognized and utilized engineering grade thermoplastics. Nylon's unique combination of high strength, good toughness, outstanding chemical resistance, and excellent wear and abrasion resistance have made it the material of choice for product designs in a multitude of industries. When used to replace wear grade metals like brass and bronze, no other material provides the combination of extended wear life, light weight, and low fabricated part cost of Nylon. Nytef Plastics, Ltd. manufactures UNIPA® Nylon stock shapes in a wide variety of types and stock shape configurations. These UNIPA Nylon products fall into the categories of Type 6/6 Extruded UNIPA Nylons and Type 6 UNIPA M Cast Nylons. While both types of Nylon are very similar, there are performance and availability differences between the two grades that should be noted: UNIPA M Type 6 Cast Nylons: offer improved wear resistance are available in larger rod diameters (up to 13" dia.) are available in larger plate sizes (up to 48" x 96") Nytef Plastics utilizes a proprietary nylon casting process to produce UNIPA M Nylon 6 stock shapes. This process allows Nylon rods, plates, and tubular bars with very thick cross sections to be economically produced with uniform physical properties and minimal internal stress levels. Nytef Plastic's UNIPA M Nylon 6 stock shapes are available in a wide range of grades including lubricated, heat stabilized, and fiber reinforced products. UNIPA M Nylon 6 materials are offered in a complete range of round rod, heavy gauge plate, and tubular bar sizes. |
