Moderate amounts of UV light can promote mineral metabolism and vitamin D formation in human’s body, which is beneficial to our health. But long-term exposure to UV light will cause damage to the skin.

Global energy is accelerating the transition to efficient, clean and sustainable direction, and the development of clean energy is also an important factor affecting the global economy and environment. Photovoltaic solar energy has the advantages of low-carbon, environmental protection and high efficiency.

Silicone adhesive can be obtained at room temperature by using different silicone polymers, additives and fillers, after heating or radiation curing. Silicone adhesives have excellent adhesion properties and high temperature resistance, which are widely used in electronics, construction, automotive, aerospace and other fields.

Coating is a kind of liquid or solid material which could be cured on the object surface under certain conditions to act protection, decoration or other special functions (such as insulation, rust, mildew, heat resistance, etc.).

Infrared ray is a kind of electromagnetic wave, with the wavelength between visible light and microwave, ranging from 760nm to 1000 μm.

Polycarbonate (PC) is a kind of thermoplastic engineering plastics with excellent comprehensive properties. It has excellent electrical properties and good light transmittance, it is the only one with good transparency among the five general engineering plastics, its transmittance of visible light can reach more than 90%!

Polyamide(PA for short) commonly known as Nylon, is the general name of the thermoplastic resin containing repeated amide group -NHCO- on the main molecule chain. PA has good comprehensive properties, like mechanical properties, heat resistance, wear resistance, chemical resistance etc.. It’s easy to process, and is usually reinforced with glass fiber and other fillers.

Powder coating, which composed of resin, color fillers and various additives with air as dispersion medium.Its solid content approaches 100%, there is no organic solvents. So it’s a eco-friendly type coating.

The rubber sealant is a kind of sealing material which used rubber as main substrate, it is generally produced by mixing processes with additives such as softener, curing agent, reinforcing filler, antioxidant.
