HDPE resin is not naturally stabilized, however iPoly adds UV inhibitor components during their process, so the sheet is thoroughly stabilized inside and out. This means that the physical strengths of Sani-Armor sheet will not deteriorate when subjected to full sun or other UV light sources.In the present study, the carbon black is used as a UV resistant additive which is mixed with the base HDPE material under different concentration starting from 1% to 3%.HDPE. High Density Polyethylene (HDPE) is an ethylene-based polymer plastic which is created by exposing petroleum to extreme heat and pressure. It’s among the most commonly used plastics worldwide, and in addition to UV resistance, has a variety of useful traits.

Is black plastic more UV resistant?
The addition of carbon black is a low cost and typically very effective way of creating UV resistant plastics. In addition, fluorinated polymers such as PTFE and PVDF can demonstrate very good UV stability in their natural state.
Can HDPE withstand sunlight?
High-density polyethylene (HDPE) is recommended due to its high strength property as well as it can withstand continually 110 Celsius Degree. For usage in the direct sunlight, it is recommended to add UV stabilizer or add at least 2.5% carbon black. With the UV stabilizer, HDPE, PP, etc can be used under the sun.

What is a good UV resistant plastic?
Certain plastics such as acrylic, Ultem®, PVDF, and PTFE are inherently UV stable.
Is black Delrin UV resistant?
It offers balanced properties and is resistant to UV light. Delrin 527 is UV stabalized.

Is black ABS UV resistant?
ABS pipe usually contains sufficient carbon black to provide protection from sunlight. The effects of ultraviolet radiation are substantially reduced in black pipe which enables its use in outdoor applications.
Does UV light damage plastic?
When absorbed by plastics, UV energy can excite photons. This, in turn, can create free radicals. Then, before you know it, degradation occurs, as catalyst residues will often act as receptors. The fact is, lots of pure plastics simply cannot absorb UV radiation, putting your project and its components at severe risk.
Is PVC plastic UV resistant?
When exposed to direct sunlight, CPVC and PVC shows “UV degradation”, but only between 0.001 to 0.003 inches. Once pipes are removed from the direct exposure, the ultraviolet rays no longer affect them. Long-term sunlight exposure can decrease the CPVC and PVC’s impact strength and resistance.
Is polypropylene plastic UV resistant?
Polypropylene is highly susceptible to degradation by UV radiation in its base form (i.e. no pigment or additives). The material becomes brittle after prolonged exposure. In fact, basic polypropylene can lose up to 70% of its mechanical strength after 6 days worth of exposure to high-intensity UV radiation.

How do you protect HDPE from the sun?
A typical additive used to protect outdoor applications is carbon black. In most applications, carbon black in concentrations of 3% or more are known to protect HDPE from the sun.
Is carbon black UV resistant?
UV radiation is not damaging to carbon black, and carbon black’s presence slows or prevents the destructive absorption of radiation that can impact flexibility, mechanical strength and opacity of the polymer.
Is polyethylene UV stable?
The regular High Molecular Weight Polyethylene (HMW-PE) as a standard is not considered to be UV stable. When exposed to sunlight and other UV light it will degrade fairly quickly. Extended exposure to sunlight radiation, and ultraviolet rays in particular, results in polyethylene being weathered.
What type of plastic is used for outdoors?
High-density polyethylene, or HDPE, is perhaps the most versatile plastic for outdoor use. Many park benches, tables and chairs are now made using HDPE plastic, and playground equipment, in general, is made of HDPE thanks to its sturdiness.
Does plastic block UV rays?
Most acrylic plastics will allow light of wavelength greater than 375 nm to pass through the material, but they will not allow UV-C wavelengths (100–290 nm) to pass through. Even very thin acrylic sheets of less than 5 millimeters (mm) do not let UV-C light penetrate.
Is HDPE weather resistant?
Resistance: Not only does HDPE sheet feature a high chemical and impact resistance, but it also is resistant to rotting, insects, mildew and mold. Weatherability: HDPE sheet is often used for outdoor applications as it can stand some of the most extreme weather.
Is HDPE stronger than acrylic?
Additionally, while both materials are strong and durable in their own way, HDPE is better suited for applications that require tensile strength, while acrylic is more impact resistant. HDPE is also more chemical and water resistant; acrylic only provides moderate protection against water and some chemical compounds.
Is HDPE waterproof?
Answer: Yes, HDPE is appropriate for building foundation waterproofing. In addition to helping waterproof, it can also act to help protect the foundation from root intrusion.
Is black acetal UV stable?
Delrin® 527UV BK701 is a black homopolymer acetal that has been enhanced with UV stabilizers. It is also available in natural on a custom run basis. Developed by DuPont to replace Delrin® 507, this material is particularly suited to automotive and other outdoor applications.
