UHMWPE YARN

UHMWPE, also known as ultra-high molecular weight polyethylene yarn, is a linear structural polyethylene with a relative molecular mass of more than 1.5 million. It is listed as one of the world's three major high-tech fibers along with carbon fiber and aramid.

Higher thermal conductivity: The thermal conductivity of ultra-high molecular weight polyethylene is relatively high. For example, the thermal conductivity of ordinary ultra-high molecular weight polyethylene fiber is greater than 0.15W/mK, while the maximum in-plane thermal conductivity of ultra-high molecular weight polyethylene film manufactured by Toray is as high as 18W/m・K, which is much higher than ordinary textile fibers and plastic films. It can quickly conduct heat. When the skin contacts it, it can accelerate the heat dissipation on the skin surface, making people feel cool. Regular molecular chain structure: Ultra-high molecular weight polyethylene has a regular, symmetrical, non-polar chain structure and a straight chain structure. This structure is conducive to heat conduction, so that the material can more effectively take away heat from the skin surface when it contacts the skin, enhancing the cooling performance Low hygroscopicity: The hygroscopicity of ultra-high molecular weight polyethylene is very low, and moisture is not easy to enter the material. This makes the material not produce a stuffy feeling due to absorbing moisture on the skin surface when it contacts the skin, and always maintains a relatively dry state, thereby enhancing the cool feeling.

In the past, the production capacity of ultra-high molecular weight polyethylene was not large, and it was mainly used in the military field. Ultra-high molecular weight polyethylene yarn is an important material for making bulletproof vests, bulletproof helmets and protective armor. Its high wear resistance and toughness make it one of the first choices. In addition, it can also be used for the shell of military equipment, the protective outer shell of radar, etc. With the increase of its production capacity.

Ultra-high molecular weight polyethylene itself has a certain cooling property. Its high thermal conductivity can quickly conduct heat. When the human body touches it, it can accelerate the heat dissipation of the skin surface, making people feel cool. Coupled with the design of ice peas, the air permeability and heat dissipation of the mattress are further enhanced, allowing people to stay cool and comfortable during sleep, especially suitable for use in summer.
