1．Application of D2W Oxidation of Biological Products:
D2w oxidizing biodegradable additives are suitable for various PE (such as: HDPE, LDPE, LLDPE, CPE, MDPE), PP (BOPP, OPP), and PS products and other materials. 99%PE (polyethylene)+1%d2w (oxidizing biodegradable additive)
Biodegradation is defined as a phenomenon caused by oxidation and cell-mediated simultaneous or sequential progress.
Solution: d2w oxidized biodegradable = oxidation + biodegradable d2w oxidized biodegradable
2．What is D2W Oxidation of Biological Degradation (D2W Oxidation of Biological)
D2w is a low-cost additive that can degrade polyethylene and polypropylene plastics into a biodegradable form. The plastic molecular chains are first broken down into small units, so that microorganisms can decompose these small units into carbon dioxide and water. Soon after the product with additives is manufactured, the degradation reaction begins. However, adding stabilizers to the oxidative degradable plastic additives delays the action of the additives with oxygen, and does not undergo the degradation reaction within the regulated time, so it can The product life can be adjusted for the product. d2w’s additive engineering breaks the carbon molecular bonds of plastics, resulting in lower molecular weight and loss of material strength. The material strength is gradually broken, but plastics will not only become plastic fragments, but under atmospheric pressure and external pressure, the molecular weight will be less than 40,000 Daltons. Microorganisms can decompose these small molecular units, which is “biodegradable.” This process will continue until the plastic becomes carbon dioxide, water, cell biomass, and trace elements.The same is plastic, adding d2w will produce unexpected effects!
Plastic is a strong, durable, lightweight, safe and versatile raw material. Plastics will eventually degrade, but this process will take decades, or even hundreds of years, to happen. This is a very long time. During this period, if these plastics are not recovered or recycled, they will cause serious environmental pollution. But if we switch to our d2w plastic products, we can effectively control or reduce this “white pollution” problem. Whether in the sea, land, sewers, woods, parks or other places, as long as there is oxygen, d2w biodegradable plastic products will begin to decompose in the natural environment after the predetermined service life. Once the degradation process starts, it will continue.
3．Classification of Bio-degradable
Basically, there are two main methods for plastic biodegradation, oxo-biodegradable and hydro-biodegradable. Both are chemically decomposed first, the former is through oxidation, the latter is through hydrolysis, and then biological decomposition is carried out. Both decomposition will release carbon dioxide, but hydro-biodegradable will also produce methane (CH4). Both methods can decompose plastics, but only oxo-biodegradable can be recycled. In addition, the hydro-biodegradable method is much more expensive than oxo-biodegradable.
4.D2w oxidative biodegradation technology principle
d2w oxidative biological double degradation has passed the American ASTM standard (ASTM 6954-04) test. The degradation process includes (stage) oxidative fragmentation and (second stage) biodegradation-which meets the standard of degradation in the environment.
Plastic products manufactured by science and technology can be oxidized and decomposed. The principle is to add a small proportion (usually 1%) of additives (pro-degradant) that can help decompose in the process of manufacturing plastics, thereby changing the plastics characteristic. When the product loses efficacy or is not needed, that is, when the product’s life cycle is set (controlled by additives), the degradation effect will begin to emerge. The process conforms to ASTM 6954-04 and is certified by RAPRA. With this biodegradable plastic technology, existing machinery and labor can be used, so little or no additional costs are required. d2w? Additives not only break the plastic into small pieces, but also break down the plastic from the molecular structure level into specific small units by the additives, so that microorganisms (bacteria and fungi) can enter and take up carbon and hydrogen and decompose further. This is “Biodegradable”. This process will continue until the material is decomposed into carbon dioxide, water and biomass (Biomass), and there will be no residual organic polymers in the soil. Oxo-biodegradable plastic has passed all common ecotoxicity tests (ecotoxicity tests) under the international standards of ON S 2200 and ON S 2300, including tests for seed germination, plant growth, and animal survival (water fleas and earthworms).

Controllable plastic life:
We can provide customized plastic products according to your specifications and requirements to control the final service life. We have five degradation cycles: 6 months, 12 months, 18 months, 24 months, and 36 months. d2w completely decomposed plastic products under normal storage conditions, from the date of manufacture (printed on the additive packaging bag), the product has a shelf life of 14 months. It is recommended that you use additives within this shelf life.
d2w additive storage method: Put the product in the original packaging bag, away from direct sunlight, and place it in a dry and cool environment, and the temperature cannot exceed 29°C (85°F). Do not place the product inside the car, in a warm garage or under outdoor scaffolding, and do not subject the product to mechanical pressure or external pressure.
