What Is UV resistant plastic?


For the longest time, plastic has been a material that is used for a lot of outdoor things. You can find plastic material all over the place the form from architecture glazing to marine dock fenders. Plastic, like human skin, tends to react to outdoor weather, like rain and sun ultraviolet (UV) radiation. Nowadays, while designing anything from plastic, you need to be protected. The plastic should be waterproof, as well as it should be UV-resistant plastic.

Plastic exposure to sunlight without any UV-resistant will cause the damaging to the material’s stuff, color, and even the polymer plastic. However, nowadays, plastic is not only restricted to small materials but is a part of many electronic devices exposed to the sun.

The following changes show that the material’s plastic is being affected by UV radiation.

  • Pressure cracking
  • Decrease in Plastic
  • Yellowing of plastic
  • Fading of Plastic color
  • An increase in surface lightening


What is UV Radiation, and why is it dangerous?

Ultraviolet or UV radiation is an electromagnetic ray generated by the sun. There are three kinds of UV radiation from the sun UVA, UVB, and UVC. Some of the radiations are short-wavelength, and some are long-wavelength.

The short-wavelength UVC radiation is the most dangerous and causes many health issues and destruction. It can upset the management of the placement of molecules, breaking them and destroying their structural reliability.

Whenever any molecule breaks or gets disturbed by anything, it will tend to release some extremely reactive atoms, which is the leading cause of danger. This destruction mainly affects plastic materials, and that effect causes a lot of deceases and other damages.


Which plastics are well known for their UV resistance?

While no plastic is entirely immune to UV rays and radiation, many plastics have high UV resistant that prolongs their useful lives, prevents elongation, and combats photodegradation’s impacts, including chalking and strength loss increased brittleness. Therefore, to ensure that your part will function as intended for as long as feasible, it is crucial to conduct thorough research before choosing a material.


One of the few production materials with built-in UV resistance is acrylic. It is a transparent material that, when used outdoors, degrades by as low as 3 percent over ten years. An acrylic is an excellent option for long-term use because it has good scratch resistance.


In playground equipment, HDPE is a thermoplastic frequently used because of its hardiness while remaining flexible. It is simple to melt and shape, yet unlike other thermoplastics, it doesn’t break into sharp, dangerous edges.



Stronger than HDPE and very impact-resistant polycarbonate is polycarbonate. It also provides transparency that is equivalent to acrylic. Additionally, polycarbonate can withstand significant temperature changes. These characteristics make polycarbonate perfect for heavy-duty items like helmets, safety windows, shields, and goggles.

PAI- Polyamide Imide:

Thermoplastic PAI is a high-performance material with excellent UV resistance and good malleability. When polyamide (nylon) and polyimide are combined, the result is PAI, a strong, chemically resistant plastic with a high melting point. Excellent wear resistance, strength, and stiffness are all characteristics of PAI. Due to these factors, PAI is frequently used for surgical tools, magnet wires, and other parts requiring precise tolerances and long-term dimensional stability.

PVDF- Polyvinylidene Fluoride:

A UV light-resistant material known as PVDF has outstanding thermal stability, abrasion resistance, chemical resistance, and UV radiation protection. Thanks to its excellent heat resistance, it is simple to weld.

There are two types of PVDF: homopolymer and copolymer. Homopolymer PVDF is more substantial, stiffer, and heat-resistant than copolymer PVDF, which is less rigid but has better impact and stress crack resistance. Both types of PVDF are used in components such as fittings, seals, gaskets, nozzles, pipes, pump and valve parts, chemical tank liners, semiconductor equipment, and more.

UV resistant plastic exposures from YONGUBOX

YONGU is a manufacturing company that develops aluminum boxes and is dedicated to innovating and perfecting aluminum boxes for consumers. Aluminum enclosures and cases are the company’s primary products.

Many of our clients tell us that it has a strong market and helps conduct business. Therefore we assist them in researching and developing aluminum boxes that are waterproof and UV-resistant.

The L series of YONGUbox is the ultimate way of UV-resistant. There are 4 models in this series A, B, C, and D, with 10 different dimensions. Model A is made of pure aluminum, while the other three are half aluminum with a plastic cover.


YONGU L03B 120*75*H Waterproof Plastic Box:

The dispensing rings help retain the functionality of being both waterproof and dustproof. They are made of shock-resistant die-cast aluminum. Their length is around 75 mm, their width is about 120 mm, and the depth may vary from 30 to 50 mm depending upon the size of the enclosed material.

These waterproof enclosures have plastic end covers, and their case is made of aluminum to make them UV-resistant. Its pad is made of an aluminum alloy and stainless steel socket cap screws with a size of M3*8. Its cross screw heads are carbon steel nickel plated with a size of M3*6 to make them more durable.

The Yongu Box has other waterproof and UV-resistant plastic boxes that can use for enclosing many other electronic devices. The waterproof electrical junction, outdoor electrical box, aluminum box, and waterproof plastic enclosure are some of our best products. The dimension and size of each box depending upon the size of the product to be enclosed.



The Yongu Box has created special featured waterproof plastic boxes that help reduce plastic’s UV resistant. The boxes have fantastic quality and are great for protecting all the outdoor electronics materials.
