Shanghai Youngtall Material Science Co., Ltd

The cotton in Xinjiang is harvested in this way. Basically, it has been mechanized. The cotton harvesting trays produced by our company’s polyurethane raw materials in Shanghai   Youngtall   Material Science Co., Ltd can harvest more than 20,000 mu of cotton per group. Xinjiang Cotton has basically achieved mechanization. Even in the busy picking season, there is no need for a large number of "cotton pickers." Cotton production in Xinjiang: 100% mechanization in northern Xinjiang, and basically realized in southern Xinjiang. Xinjiang cotton production has been mechanized early and does not require a large number of "cotton pickers". Now Xinjiang cotton has already been picked by machines. In the old days when cotton was harvested manually, spraying defoliants on cotton fields was not a rigid requirement. More and more farmers choose mechanized cotton harvesting, because of its lower cost and higher efficiency. Xinjiang cotton production is developing towards intelli

Pu wheels for skateboards   are generally made from polyurethane as the main material. The proportion of polyurethane in the wheel is various, and the firmness of the wheel is likewise various. The wheels with the firmness of 85A are fairly soft, appropriate for harsh roads, as well as the sound is really low when cabbing. It is a great selection for buddies who like to pedal as well as shop. PU wheels are products developed by the handling of chemical raw material frothing processes. PU can manage the density and also flexibility of the item, as well as the high density of abrasion resistance. Wheels with great elasticity can regulate and lower resonance during skateboarding. Reaching thickness and also elasticity requires a mix of professional signs. PU wheels are used for expert skateboarding. PU skateboard wheels supplier  presents the preventative measures for skateboarding: First, as with all sports, prepare for roller skating. Commonly known as "warm-up", you heat up y

Polyurethane skate wheels   are a suitable option for inline skating boots and also wheels. When it comes to skating,   polyurethane wheels for skateboards   are relatively unbreakable, adaptable, resilient, and also sturdy. We flaunt an engineering team that is highly efficient in the art of manufacturing exceptionally high-quality polyurethane skate wheels that can withstand damaging and also severe environmental conditions owing to their boosted physical buildings.

Polyurethane skate wheels have practically the ideal friction index for various types of skating styles. We also develop our Polyurethane Skate Tires with high tensile toughness, so they can review cracks easily and at a quicker speed. We boast a constant production of top-quality urethane parts with our continued application of spe

  Skateboard wheels were first invented in the early 20th century. Some creative children fastened old roller skates to a 2-by-4 plank. The original skateboard wheels were made of steel, which was difficult to use because the wheels had very little traction. In the 1950s, the first commercial skateboards were manufactured, still using metal wheels. By the 1960s, manufacturers realized that metal wheels were not suitable for skateboarding, so they tried to make skateboards with clay wheels. However, clay wheels are not much better than metal wheels, and they are fast and bumpy, and difficult to control. It was not until the 1970s that skateboard manufacturers began to use  polyurethane wheels for skateboards . The inventor of skateboard polyurethane wheels was Frank Nasworthy (Frank Nasworthy), who noticed that  polyurethane skateboard wheels  performed better on roller skates and thought they would be better on skateboards. The sport began when polyurethane skateboard manufacturers beg
