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 w...

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 elec...

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 S...

PU wheels are environmentally friendly tires. The main material of the tires is polyurethane. Strictly speaking, PU is also a kind of plastic. However, additives are added during the production process, which results in superior performance. It has puncture resistance, no inflation, high cost, good grip, not easy to slip, more wear-resistant, and good comfort. Rubber solid wheels are mainly used on the flat pavement of the factory workshop, which has the characteristics of low cost, puncture resistance and corrosion resistance. 1. PU round PU material can be applied to the fabric of shoes or parts that bear weight, such as high-end inline wheels,  pu pulley for skateboard , PU pads, luggage wheels, shopping wheels and other wheels. In some sports and leisure products favored by young people such as drift boards, vitality boards, skates, twist cars, etc., the wheels are generally PU wheels. WHY? Because these products need to bear individual weight, I will take the drift...

The "West wind" skateboarding team in Santa Monica, California used the abandoned keyhole pool as a venue for practicing vertical surface skateboarding, and in a while, formed the search for pool heat in California. From then on, skateboarding and surfing are completely separated not only from the equipment and the ground, but also from the personnel, and they have become a rising force. This new army did not get involved in surfing, and delved into skateboarding, and began to develop its own language, skills, clothing styles and music hobbies. Formed a new, city-led skateboarding secondary culture. The mid-1970s was a period of rapid development of the third generation of skateboarding. It is foreseeable that a new type of sports will emerge. Numerous small skateboarding companies founded by skateboarding and surfing enthusiasts have sprung up and started to compete on technical quality. The potential of polyurethane wheels is fully utilized. Continuously improving polyur...

PU skateboard wheels supplier  to share with you: On the other side of the Pacific Ocean in the late 1950s, descendants of Edison who were good at inventions turned the fantasy of ancient Divine people into a reality . In the early 1950s, the west coast of the United States was a place for hotspots. They use ordinary wood and expensive balsa surfboards for fun on the cusp. By the mid-1950s, wooden surfboards were replaced by molded polyurethane foam and fiberglass. The mobility and durability of these new surfboards made surfing popular in the late 1950s. Bringing "surf" to land Surfing failed to satisfy the local people's lifestyle of having fun anytime, anywhere, so they brought "surfing" to the land. They call it "skateboarding," which is an extension of surfing on land. The former is limited by geographical and climatic conditions, while the latter has more freedom. Residents of the sunny Southern California beach community quickly built t...
