It is known that food, drinks, colored
products, etc. exposed to UV light will ultimately become perishable or color fading
due to chemical effects. PE net with color has unfavorable outcome also if it
is under the sunlight for a long period of time. It will lead to the loss of
elongation, tensile strength, dye, and so on.
The good news is that “UV light stabilizer masterbatches”
could be one of the ways to lessen the above adverse effects on PE plastic net.
There are two UV light stabilizer masterbatches - Ultraviolet Absorbers (UVAs)
and Hindered Amine Light Stabilizers (HALS).
UVAs, also known as UV filter, function by
absorbing and dispelling harmful UV radiation to stabilize the condition of PE products
under short-term exposures.
With its regeneration
feature, HALS is the most effective UV Light Stabilizer for polyolefin
products. It works through trapping free radicals developed in the process of
photo-oxidation. Almost all kinds of products under long-term exposures are
suitable for HALS application.
With these two UV light stabilizers, PE nets
could have longer lifespan not only for playing its role in shading against
sunlight but also for preserving their vivid colors!
