PU leather is a coating of Polyurethane on a thin layer of leather. This coating imparts a glossy finish to the leather along with the value addition to the otherwise lower quality leather used. The final quality achieved is nothing better than PU.
Ultraviolet absorbing materials have important applications in which graphene is a strong candidate, yet, few efforts are being exerted to improve its absorption in the UV-region. We show that UV absorption in single-layer graphene can be enhanced by manoeuvring its electronic properties through converting it to a nanomembrane-like structure, or nanomesh.
Deep penetrating polyurethane primer weberdry prime 310 PU is a 1-component transparent low viscosity primer. It is mainly used as a primer for polyurethane waterproofing system, like weberdry 350 PU and weberdry 360 PU. It has excellent adhesion and is mainly used on absorbent substrate like concrete, light weight concrete or wooden surface.

On the other hand, short-wave ultraviolet (UV) has been widely used for food decontamination. It is a physical method and does not produce any toxic by-products (Fan, Huang, & Chen, 2017). Additionally, the capital and operating costs of UV are low, make it suitable for industrial applications (Garg, Abela, Tiwari, & Valdramidis, 2016).
Polyurethane Film is also commonly referred to as TPU, Urethane or PU film. Thermal Plastic Urethane was first developed in 1937 and has for decades been used in the manufacture of a unique class of films. There are several properties that make TPU films preferable to common films such as PP, PE and PVC are. Advantages of TPU Film

Ultraviolet filters absorb UV light generally without affecting light in the visible region. It is important to distinguish between UV-generated haze and that of air-borne particles, such as smog. The latter is made up of opaque matter that absorbs visible light as well as UV, and will not be appreciably removed by a UV filter.Haze 1 reduces excessive blue haze caused by UV light by absorbing 71% of UV.

There are 4,956 ultraviolet absorbent suppliers, mainly located in Asia. The top supplying countries or regions are China, Taiwan, China, and South Korea, which supply 99%, 1%, and 1% of ultraviolet absorbent respectively.
Ultraviolet B (UVB)-induced cyclooxygenase (COX)-2 and matrix metalloproteinase (MMP)-1 are representative markers for skin inflammation and photoaging, respectively. To evaluate compounds that may counteract the effects of UVB-induced skin damage, we developed an immortalized human keratinocyte (HaCaT) cell line with an MMP-1 reporter construct.
The inoculated samples were dried for 2 h at room temperature, packed in plastic bags and kept at 4 °C overnight. The samples (3000 g of blueberries, 3000 g of grape tomatoes, or 800 g of iceberg lettuce) were then placed in 10 L turbid wash water (2000 ppm of COD and 100 NTU of turbidity).
2-(2'-Hydroxy-3'-tert-butyl-5'-methylphenyl)-5-chlorobenzotriazole can be used in the food container. Packing and storage: Ultraviolet absorbent UV-326 is non-toxic, non-inflammable, non-corrosive matter with good storage stability.
Apart from disease-causing bacteria, your private well water or municipal tap water can also contain sediments, UV light absorbing compounds, debris or dirt that may shield bacteria and block UV lights from reaching their target. Because of this, pre-filters are an indispensable element of UV water filters.
The market for antioxidant stabilisers alone was estimated at US$1.69 billion for 2017, with the total market for all stabilizers expected to reach US$5.5 billion by 2025.
