It has been widely used since the 1950s, and it is one of the most widely used polyurethane thermal insulation steel pipes. High-density polyethylene shell has excellent anti-corrosion, heat preservation and mechanical properties, so the outer skin of working steel pipe will not be corroded by external water and air. To sum up, the polyurethane insulation pipe is safe, and its service life can reach more than 30-50 years, which is three to four times that of the traditional old insulation pipe. Polyurethane insulation pipe also has excellent waterproof, and water will not stay in the foam, and after receiving water it. The wear resistance of plastics is 4 times higher than that of nylon 66 and polytetrafluoroethylene and 6 times higher than that of carbon steel. 2. The impact strength of plastics is 2 times that of PC and 5 times that of ABC, and it can maintain high toughness at liquid nitrogen temperature (- 196 ℃). 3, self-lubricity is equivalent to polytetrafluoroethylene, the friction coefficient is only -; 4, impact energy absorption value in all plastics.
In conclusion, let us acknowledge the unsung hero that is plastic bags for cookies. Despite their controversial reputation, these bags provide us with unparalleled practicality and versatility during the baking process. From crafting perfectly shaped cookies to keeping them fresh and flavorful, plastic bags have become a valuable asset to bakers worldwide.

Nylon + solid lubricant: using the formula of authorized cast nylon, containing solid lubricant, this material has self-lubricity, excellent friction, outstanding wear resistance and pressure speed ability (5 times higher than ordinary nylon). Especially suitable for high-speed operation, can not be lubricated sports parts, is the perfect supplement of oily nylon, nylon plate has a wide range of applications, is a good material to replace steel, iron, copper and other metals, is an important engineering plastic; cast nylon widely replaces the wear-resistant parts of mechanical equipment, instead of copper and alloy as the wear-resistant parts of equipment. Suitable for making wear-resistant parts, transmission structural parts, household appliance parts, automobile manufacturing parts, screw prevention mechanical parts, chemical machinery parts, chemical equipment. Such as turbine, gear, bearing, impeller, crank, dashboard, drive shaft, valve, blade, screw, high pressure washer, screw, nut, sealing ring, shuttle, sleeve connector, etc.
Reusable lunchboxes are one of the best products you can sell in 2022. Consumers can use it to package healthy snacks and avoid food packaging. At present, food wrapping paper is the most common plastic waste in beach cleaning!
Plastic polyvinyl chloride (PVC) material is widely used in the manufacture of decorative skins and protective covers such as automobile dashboards and sunshades because of its low price and simple processing. However, in order to meet the relevant production requirements, PVC formula contains plasticizers of phthalic acid, heavy metals and other toxic substances; in addition, although PVC material itself is non-toxic, it will slowly decompose harmful hydrogen chloride gas at high temperature.
The quality of Yunnan aluminum tube customized and steel matrix with high strength hard aluminum veneer is divided into several aspects of material production, process, packaging and transportation. The main raw material of aluminum veneer is aluminum plate, which needs to be used or antirust aluminum plate, and the thickness can be divided into aluminum veneer aluminum veneer. The introduction of aluminum plate is commonly used, which can also be called anti-rust aluminum coil. Commonly used outdoors, such as pipe outer aluminum veneer aluminum plastic plate metal roof wall and other external environment, hardness and price are higher, extensibility is also higher, commonly used in aluminum magnesium manganese metal roofing (about aluminum thickness) metal wall panel aluminum honeycomb panel can pipe insulation outsourcing (about aluminum thickness) and other product uses.
