Ultraviolet resistant transparent PC plastic

Ultraviolet-resistant transparent PC plastic is a polymer material made based on polycarbonate (PC), which has multiple excellent properties and is widely used. Ultraviolet resistant transparent PC (UV resistant PC) plastic is mainly based on polycarbonate (PC) material and modified through a special process. It not only maintains the original high transparency, light weight, sound insulation, heat insulation, flame retardant and other properties of PC materials, but also has the characteristics of ultraviolet resistance, aging resistance and yellowing resistance.

Ultraviolet light cannot penetrate transparent plastics, such as materials such as polycarbonate (PC). This is because ultraviolet light has a short wavelength and cannot bypass or pass through solid materials. Ultraviolet light is divided into UVA, UVB and UVC. The longer the wavelength, the greater the harm it is to human skin. Even for plastics with high transparency, such as PC, ultraviolet light is significantly attenuated in them. Therefore, ultraviolet lamps are usually made of high-purity quartz glass.

PC-1100 and PC 1100U transparent weatherproof medium-viscosity ultraviolet-resistant plastic particles are commonly used plate-grade raw materials. Chi Mei PC-108U transparent weather-resistant and UV resistant raw material, suitable for plate and sunshade production scenes. Saudi Basic Industry PC-1003R is a low-flow thermally stable UV resistant modified raw material with its own release agent. It has high transparency, high toughness and weather resistance. It can be used in electronics, automobiles, outdoor lighting and other fields.

Medical field: PC materials have a wide range of applications in medical care, such as protective goggles, protective masks, plasma separators, etc., and have the characteristics of high light transmittance, balance between rigidity and toughness, bacterial inhibition and heat-resistant steam disinfection. Optical lenses: PC can be used to make corrective lenses, which have the advantages of optical purity, transmittance, ultraviolet radiation protection and strong astigmatism resistance.

Which material is good for uv400 glasses?

The material selection of UV400 glasses needs to be based on specific needsWhat does UV PC mean?, polycarbonate (PC), TAC polarizer, glass lens, and nylon lens each have their own advantages. Polycarbonate (PC) lensesWhat does UV PC mean?: Advantages: Lightweight and impact resistantWhat does UV PC mean?, is ideal for children or for outdoor activities. It comes with an anti-ultraviolet function and has a light transmittance of more than 90%, which can effectively protect eyes from ultraviolet damage. Disadvantages: The surface is easy to scratch, so it needs to be equipped with anti-scratch coating to improve durability.

Priority should be given to gray/tan lenses: they can relieve strong light stimulation better than ordinary dark lenses and do not affect color recognition. The resin material is lighter: it is more impact-resistant than glass material and is not easy to compress the bridge of the nose when worn for a long time. It is especially suitable for the elderly. Scene adaptation recommends daily commuting: Choose color-changing lenses (photochromic) to cope with the changes in light day and night, and the indoor is transparent and the outdoor automatically turns dark.

Such glasses usually have clear "UV400" and "100% UV blocking" logos. Lens color selection tips It is recommended to choose amber or brown lenses early after surgery. This color can filter blue light and improve contrast. After recovery and stabilization, the gray lens is suitable for daily use and can truly restore the color without color cast. Be careful to avoid pure black lenses, which may affect the judgment of light sensitivity.

What does the PC-UV400 printed on my sunglasses mean?

1. Your sunglasses are printed with the words PC-UV400, which means that the lenses are made of polycarbonate (PC) material. PC lenses, also known as polycarbonate lenses, are a thermoplastic material. In contrast, thermosetting materials, such as ordinary resin lenses, cure when heated. PC lenses have excellent toughness and impact resistance and are not easy to break, so they are often used for safety lenses.

2. UV400 means 100% resistance to ultraviolet rays. Ultraviolet light refers to solar light with a wavelength between 200nm and 380nm, including three categories: UVA wavelength between 315nm and 380nm, UVB wavelength between 280nm and 315nm, and UVC wavelength between 200nm and 280nm. Ultraviolet light accounts for about 13% of the solar light (290nm-2000nm) reaching the earth's surface, of which UVA accounts for 97%, UVB accounts for 3%, and UVC is close to 0.

3. About the core characteristics and uses of PC lens materials: The uniqueness of the material PC materials are inherently impact-resistant. The lenses are not easy to break even if they are impacted by external forces. Therefore, they are widely used in sports glasses or children's sunglasses. Functional advantages These materials come with 100% ultraviolet resistance (UV400) and are thinner and thinner than traditional resin lenses. They are suitable for long-term outdoor wear and are not easy to feel pressured when driving.

4. UV400 means 100% resistance to ultraviolet rays. For sunglasses, the UV index, which is the effect of filtering out ultraviolet rays, is a very important standard. The UV index of most sunglasses is between 96% and 98%. Dark lenses are better than light lenses. UV400 is 100%. It means 100 percent resistance to ultraviolet rays.

5. Sunglasses: The main function is to block strong sunlight, especially ultraviolet ray damage to the eyes. Sunglass lenses are usually coated with a UV400 protective coating, which can effectively filter out 99% or more of harmful ultraviolet light. Sunglasses: Pay more attention to decorative effects. Although some high-quality sunglasses also have certain ultraviolet protection functions, their original design intention is more for fashion purposes.

What is a wavy board? Why do villas and mansions like to use it?

1. Easy to install, cost-controllable wave plates do not need to reserve expansion holes for installation, and can be directly drilled and fixed, with low maintenance costs. For large-area decoration projects such as villas and mansions, the construction efficiency advantage is significant. Unique in shape, enhancing the aesthetic feeling of space. The wavy board breaks the horizontal and vertical design of the traditional wall and gives the space a dynamic aesthetic feeling through the undulating wave shape. It is rich in colors and can match modern, light luxury, industrial and other decoration styles, satisfying the villa owners 'pursuit of personalization.

2. Having said so much, what is a wavy board? Wave board is a new type of fashionable artistic interior decoration board. This decoration material is mainly used in decoration projects such as hotels, clubs, home decoration, song and dance halls, resorts, shopping malls, mansions, villas, etc., and is especially suitable for designing doors, doorways, background walls, TV walls, colonels, bars, doors, ceilings, display shelves, etc.
