Shanghai Youngtall Material Science Co., Ltd

Polyurethane material is the abbreviation of polyurethane, it is a polymer material. Polyurethane is an emerging organic polymer material, known as the "five plastics". Because of its excellent performance, it is widely used in many fields of the civil economy. Product application areas involve light industry, chemical industry, electronics, textile, medical, construction, building materials, automotive, defense, aerospace, aviation, etc. A new type of polyurethane caster is also emerging in the caster industry. Let's take a look at it. Pu Castor Wheels What is the material of polyurethane casters? The elastic body of  pu castor wheels  has good performances such as abrasion resistance, chemical resistance, high strength, high elasticity, low pressure resistance, strong shock absorption, tear resistance, radiation resistance, high load bearing and shock absorption buffer. Polyurethane casters also have a wide range of hardness, ranging from Shore A10--100. There

Pu castor wheels  are very widely used, which will involve many industries, and the development of products will become more specialized and become a special industry. At the same time, it has good processing performance such as short demolding time and stable size. The prepared wheels can meet the transportation requirements regardless of the indoor and outdoor ground driving. There is no wheel mark on the driving, the floor is protected, the rotation is light, flexible and quiet. Adopting a great advantage lies in green environmental protection, which reflects the concept of a low-carbon Expo. With its high mechanical strength, excellent abrasion resistance, excellent oil resistance, outstanding power, and a large number of applications on rollers. Based on many years of research on the Pu caster industry, combined with the current state of development of the Pu caster industry market, the Pu caster market data was collated through a research team, and the Pu caster industry was r

For a supplier engaged in the development and production of sports products and parts for industrial applications, in addition to being very confident in the quality of the products, we have a professional understanding of the expertise of  pu castor wheels . Some common caster problems are also frequently asked by customers. We have summarized them and hope to help you. 01. How is the surface of the caster bracket generally treated? The most common stand colors on the market are two colors: silver and black. Silver is electroplated and coated with a layer of zinc or chromium to make the color of the bracket silver. The black ones are usually made black by electrophoresis. Another high-end caster uses powder spraying technology, and the color can be customized according to customer needs, of course, the price is relatively high. Whether it is electroplating, electrophoresis or dusting, the purpose is to prevent the surface of the bracket from rusting. Whether it is electroplatin

Three important information when buying skate wheels Hardness (1) The concept of hardness The ability of a material to locally resist the intrusion of hard objects into its surface indicates how soft or hard an object is. You can feel the soft hardness of the object with a pinch. (2) Hardness measurement method For different materials, there are different measurement methods for hardness, corresponding to different standards. Black Pu Pulley For Skateboard Skateboard pu wheels  uses the shore hardness test. it was first proposed by the British Alert F. Shore. It is also called the Shore hardness in the rubber and plastic industries. The measurement principle is the same. Under standard conditions, the standard pressure needle is pressed into the surface of the object, and the depth of the indentation is examined to indicate the hardness of the object. The difference is that the shape of the pressed pin is different. Shore A uses a circular truncated cone, while Shore
