GY-DG-84 Highly Effective Degradable & Decompositional Additive for Plastic

Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO. LTD. (GYC) has been focus on the highest end & environmental innovation and R&D for a long time. GY-DG-84 offers a complete range of solutions for the defects of traditional degradable materials, such as high price of PLA/less of applications/cannot combine with the general plastic, etc.

The concept of degradable plastic refers to: It can be decomposed into small molecules polymer by microorganisms from sun or soil in the short time after getting the expired time of plastic product. The delayed period of degradable plastic which means it is from the beginning of processed into plastic product to a small transverse cracks in time by the external environmental conditions. Different degradable with the different delayed period、the requirement length for delayed period of various plastic is also different. As the example, the delayed period of plastic film is not less than the growing season of crops. GYC Nano decomposable material not only has high efficiency degradation ability but also provides the following advantages:

• Can use compound and add in the variety of plastic: PP.LDPE.HDPE.LLDPE.…etc.
• Less efficient usage rate and achieve large number of applications of degradable plastic for human
• The degradation delayed period fixed and appropriated length, it can control the start time of degradable plastic
• High decomposition speed, it can be degraded by environment, soil, sunlight, humidity, UV light and the oxygenation in the air after used
• PLA material which made by natural corn or starch is an expensive, low heat resistant product. Moreover, this item can’t be used widely. Comparing with PLA, GY-DG-84 has well price performance ratio.
• PLA materials need a special environment at high temperature 50 ° C, humidity 50% ~ 60%, it also takes about 40 days to decompose naturally, difficult to decompose in open-air environment
• The recycle of PLA should be separated and classified exactly, it will increase the cost and time of recycle
• Can be combined with traditional petrochemical products such as :PP.PE. LDPE.HDPE.LLDPE…etc

GY-DG-84 was developed by GYC technical department for this field which has all the advantages of degradation materials, and it is one of the degradation materials of high efficiency optical degradation polyolefin. GY-DG-84/85 contained organic nanostructures which can promote polymer to generate free radical and leaded to photo-oxidation reaction. In the sun and other light sources, it used the energy UV light of light degradation and the role of oxygen in the air to degrade plastic as small molecule compounds. GY-DG-84 is especially for light degradation, traditional polyolefin film products. For example, it can add into PP/PE/EVA/PC and it also can use as agricultural film, agricultural film, bags, shopping bags, packaging film construction, garbage bags and other additives. Within the effective and significantly accelerated the degradation of the light and also has a non-toxic, odorless, tasteless, non-flammable and other effects.
In addition, GY-DG-84 can replace the high price of PLA, and then overcome the defects of bad processing and unlike polyolefin or general pan with plastic; realize human’s desire and pursuit for environment, environmental protection and energy saving.

Use and dosage

•  GYC technology recommend the dosage for GY-DG-84 is generally only 0.01~1wt% by weight of polyolefin. It can attach the ability for degrading polyolefin within the period of particular time, and effectively control the lifetime of a polyolefin film products. Customers and R & D staff can adjust the dosage according to the different application and requirements.

•  Lined with plastic bag and outer layer is woven bag
   

Storage

• Need to be sealed, and. it will absorb the water while exposing in the air. Pay attention to moisture.
• In case of strong acid, decomposed into stearic acid and corresponding iron.
