关于聚氨酯
Polyurethane Properties聚氨酯特性
A polyurethane is a polymer comprised of a chain of organic units joined by urethane links. EHC polyurethanes belong to a group of polymers called elastomers. An elastomer is a material that will recover its original shape after deformation. Polyurethane's superior wear resistance, rebound and load bearing properties separate it from other elastomers. Polyurethane raw materials are liquid and can be cast into limitless shapes and sizes in low pressure moulds while other elastomers are mixed, milled and moulded using traditional industry techniques.
聚氨酯是一种高分子链组成的聚合体。依合斯聚氨酯产品属于弹性体。弹性体的材质使其变形后能恢复原来形状。聚氨酯的优良耐磨性，反弹性和承载性能使它有别于一般弹性体。聚氨酯原料是液体，可被注射入任意形状和大小的模具进行浇铸，而其他热塑性弹性体采用传统工艺进行混合，研磨及压铸。
Polyurethane’s unique properties offer many advantages over other materials in dynamic applications. 在工业领域，聚氨酯特有的特性使其比其他原材料更有优越性。
Polyurethane vs. Metal 聚氨酯与金属
Lightweight, flexible and resilient urethane offers greater impact, corrosion and abrasion resistance than metal. Polyurethane is ideally suited where low noise and smooth operation are required. A cost effective alternative requiring less expensive fabrication, infinitely mouldable polyurethane is also suited to applications requiring non-sparking and non-conductive material. 轻便，灵活和富有弹性的聚氨酯比金属更具抗压性和耐腐蚀性。聚氨酯尤其适用于对低噪音和平稳运行有特别要求的客户。聚氨酯成本低，制作费用低，可随意浇铸，适用于要求不产生火花和不导电材质的设备。
Polyurethane vs. Plastic聚氨酯与塑料
Unlike plastics, polyurethane is suited for dynamic applications. Its elastic behaviour will allow recovery after the application of high loads rather than the deformation of a plastic. Versatile and resilient polyurethane rollers provide longer service life than metal, rubber or plastic counterparts.
不同于塑料，聚氨酯适用于动态应用。聚氨酯的弹性行为使其在高负荷下运行后仍能恢复原状，而塑料制品则会变形。多种多样的弹性聚氨酯滚轮的使用寿命比金属，橡胶和塑料制成的滚轮都要长。
Polyurethane vs. Rubber 聚氨酯与橡胶
Considering its colourable and castable nature, its extended hardness range, low wear and superior load bearing capacity, polyurethane is a smart substitute for rubber. The relative benefits of high abrasion, cut and tear, oil and ozone resistance are delivered in an extensive range of molded products for many industrial applications.
考虑到着色和浇铸料的性质，选择具有更大硬度范围，低磨损，优越承载能力的聚氨酯替代橡胶是明智的。许多工业受益于这种高耐磨，低损耗，耐油，抗臭氧聚氨酯产品。
Bonding Advantage
粘接优势
One crucial advantage of cast polyurethane is that it can be bonded effectively with metals, composites or plastics during or after the moulding process. Core construction components (or inserts) may include wheel hubs, bearings, fasteners, injection-molded parts or castings. Because the adhesion between polyurethane and other materials is often stronger than the elastomer itself, cast urethane rollers provide high tear strength for rugged performance over extended service life.
浇铸聚氨酯的一个关键性优势是它可以在成型过程中和过程后与金属，复合材料或塑料组件有效粘接。滚轮产品的核心组成部分包括轮毂，轴承，紧固件或铸件。聚氨酯与其他材料的粘接强度往往强于弹性体本身，所以聚氨酯滚轮具有高抗拉强度，使用寿命长。
Moulding Benefits
浇铸优势
Liquid castable polyurethane materials can be machine processed and dispensed with precise control over ingredient proportions and temperature levels. Hot liquids are introduced to moulds at low pressure and cured at high temperatures. This exceptional characteristic of polyurethane permits custom moulds of virtually any shape or size.
液体的浇铸聚氨酯材料可机加工，并在过程中精确控制配方和温度。加热后的聚氨酯被低压注入模具在高温下成型。聚氨酯材料这种特殊的特性，使其可被浇铸成客户需求的任何形状或大小的产品。
Strength/Durability
强度/耐久度
Compared with conventional elastomers and plastics, polyurethane products offer superior strength, durability and versatility. Because polyurethane is more resistant than other materials to cracking, tearing, breaking, swelling or deterioration, polyurethane components result in fewer replacement parts and operational interruptions. The unique flex and compression properties of polyurethane provide industrial solutions for high-impact operations, intense load-bearing applications and harsh operating environments.
与传统的弹性体和塑料相比，聚氨酯产品的强度，耐久度和多功能性更出众。聚氨酯比其他材料更不易开裂，磨损，断裂，起泡或变形，因此聚氨酯产品的更换率和故障率较低。聚氨酯独特的伸缩和压缩性能，为高压，强负载和苛刻工作环境的工业提供了解决方案。
