GY-DG-80 Eco-Friendly Solution to Biodegradation
GY-DG-80 is a polymer containing high polymers of polycaprolactone (PCL) as well as long-chain and natural polysaccharides. Ultraviolet and oxidation will rapidly lead to a chain scission of polymers, causing the plastic to break into smaller pieces. After that, the polysaccharides in GY-DG-80 which is with high bonding strength will integrate into the plastic material and further induce a huge amount of bacteria to decompose the plastic. The plastic in the end will be decomposed into calcium oxide, water and carbon dioxide via biodegradation.
GY-DG-80, eco-friendly and biodegradable granules, can be used or processed with ABS, PS, traditional and general plastics including polyolefins to produce biodegradable products, which results in a broad applied field such as agriculture, industry, daily necessities, etc.
Description
Intro
Environmental issues have become market trends and even turn out to be a part of the factors that increase the product value. Hence, a huge number of international labels show their initiative on using, producing and selling products that are composed of bioplastics. Poly lactic acid (PLA) is an eco-friendly material that people currently pay much attention to. However, PLA is with a short period of storage and high price, and features weak oil/heat resistant properties; additionally, it cannot be recycled, mixed with other general plastics or be processed easily and efficiently. Due to the flaws, PLA can still not be used largely and broadly as yet.
GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) is currently the largest manufacturer of functional additives in Asia where two of our factories are built. As for a long period of time we put our efforts on high-end, eco-friendly and innovative research and development to improve the existing flaws of biodegradable materials on the present market in order to develop materials that can be processed efficiently and for mass production, we are able to provide a total solution to the worldwide processing or producing issues of biodegradable materials.

Adding Rate
Recommended adding rate: 30%-50%
The adding rate is regarded as general guideline which can be adjusted according to type of material, required performances, and environmental conditions where plastics are to be buried.
The actual decomposition times vary depending on type of material, temperature, humidity, sunlight, and other environmental and climatic factors.
Decomposition Efficiency
Formula: GY-DG-80*50% with PE*50%
Product: PE packing material with 20µm thickness
Conditions: temperature range 28-33℃
Evaluate and observe the changing of the buried packing material on day 0, day 150, and day 300.
Result:
Decomposition efficiency vary depending on temperature, humidity, sunlight, microbes, and other environmental and climatic factors.According to the burying test, the packing material is found to be decomposed 80% after 300 days.
Packing
25KG/bag
Storage
Store in a cool, dry, and well-ventilated place. Avoid direct sunlight.
