Analysis of anti-hydrolysis, anti-bacterial and anti-virus schemes for improving quality and efficiency of biodegradable materials

On January 19, 2020, the National Development and Reform Commission and the Ministry of Ecology and Environment issued a new version of the plastic limit, the Opinions on Further Strengthening Plastic Pollution Control, which restricted the use of plastic in four key areas (non-degradable plastic bags, disposable plastic tableware, disposable products for hotels and hotels, and rapid plastic packaging).

With the introduction of plastic restrictions, and people’s awareness of environmental protection, the market for biodegradable plastics is becoming increasingly hot. However, biodegradable plastics still have some shortcomings in the aspects of manufacturing cost, self-performance, processing performance and downstream application performance. Based on this, enterprises of the whole industry chain have put forward their own solutions, aiming at making concerted efforts to make the whole industry develop faster.

How to improve the comprehensive performance of degradable plastics?

Conventional biodegradable polymer materials, such as PLA and PKAT, have a common shortcoming. In humid environment, especially at high temperature, the ester bond in the molecular chain is prone to hydrolysis, which reduces its comprehensive performance and service life. The hydrolysis of ester bond is the root cause of the service life decline of ester based polymer materials.

Hymax ® antihydrolytic agent can react with carboxylic acid generated by polyester decomposition to produce stable urea-based compounds with no side effects, thus slowing the hydrolysis of polymer ester bond and effectively improving its tensile strength, impact strength and other comprehensive mechanical properties.
The HYMAX ® anti-hydrolytic agent can systematically solve the problem of the degradation of the comprehensive performance of PLA and PKAT biodegradable materials due to hydrolysis, thus extending their service life.

How to increase the antibacterial activity of biodegradable plastics?

Besides having good heat resistance and no toxic substances release, antibacterial advantages of long period of validity, compared with other inorganic antibacterial agent, AntibacMax ® high transparent antimicrobial chemical performance is stable, color transparent inorganic material as the carrier, used in transparent polymer material such as PLA, can effectively maintain transparency of the material, avoid yellowing, hair spray. After professional microorganism test, its antibacterial and antiviral properties can reach 99% and above.

Biodegradable materials are green materials to solve global white pollution, and their application prospects are self-evident. How to make this environment-friendly material applied in various fields and quickly promote the overall development of degradable industry will be a great opportunity and challenge for every enterprise in the industrial chain.
