Polybatch® DEG 68 UK
“An extra additive used in our products to make them degradable and overall better for our environment”
POLYBATCH DEG 86 UK is a masterbatch additive which degrades polythene under the influence of light and heat. The addition of 2 to 3 % POLYBATCH DEG 86 UK will produce a photo chemically and thermally degradable film.
Polythene containing POLYBATCH DEG 86 UK will not degrade before being exposed to UV light.
Once the polythene has been exposed to UV light, the degradation reaction will be triggered an even continues in the dark. It will be accelerated by heat.
Once the polythene has been transformed into a fine powder, many studies have shown that biological degradation will take place. The end products of biodegradation will be carbon dioxide and water, with a very small residue of non-toxic inert mineral material. Biological degradation can start when the molecular weight has been drastically reduced and when the surface area of the disintegrated plastic has been enlarged.
The residues of degraded polythene are NON-TOXIC
POLYBATCH DEG 68UK contains active metal ions embedded in LDPE. Degradation starts only after the metal ions have been activated by exposure to a UV light source.
The degradation speed is mainly dependent on:
-the concentration of POLYBATCH DEG
-the thickness of the film
-the types of resin
-the presence of antioxidants and pigments
-the type of exposure
Moisture content (%): <0.15
Colour: Light Brown Pellets
“In response to growing interest in the subject of Degradable Plastics, our polymer suppliers have introduced Polybatch ®DEG 68, a highly concentrated masterbatch, which can be added to Polyethylene to catalyse degradation under the influence of sunlight and/or heat.
Polybatch ®DEG technology has been used for many years for the production of agricultural mulch films, which are required to be degraded at the end of the growing season so that they can be ploughed into the soil.
Films containing Polybatch ®DEG 68 can be stored for extended periods away from direct sunlight or heat sources. Upon exposure to sunlight, the degradation reaction will be initiated. It will then continue, even in the dark, and will be accelerated by heat. Heat alone will also promote the reaction. Tests have shown that a 50 micron Polyethylene film containing 4% Polybatch ®DEG 68 will be degraded to total embrittlement in less than 2 months when stored at 70 degrees C. This temperature is typical of that reached in composting situations. Higher addition rates will increase the speed of degradation. It desired, stabilisers can be added to delay the onset of degradation.
Several academic studies have shown that when the molecular weight of Polyethylene has been reduced sufficiently, it will become digestible by microorganisms in the soil and therefore become truly biodegradable.
Therefore, the ultimate degradation products of films
containing Polybatch ®DEG 68 will be water,
carbon dioxide and a small amount of non-toxic mineral
matter. All ingredients of Polybatch ®DEG 68 are positively
listed for use in food contact applications under European
Directive 2002/72/EC. There are no specific
