How to develop products based on material properties Biodegradation is by no means the core function of a material？
For a biodegradable material to gain a foothold in the market, it must be a unique combination of biodegradation + material properties. Different properties can be added according to different markets, so "biodegradation +" The content after the number is the factor that the industry needs to consider.
Utilize the rapid degradation of biodegradable materials:
Successful case: PGA/PLA is used as a temporary plugging agent for fracturing in shale gas exploitation
Performance matching:
1. High strength before use;
2. When used in 90 degrees hot water , 6h will lose its mechanical properties and becomes muddy, with a degradation rate of more than 15% in 10h;
3. Degrades in 90 degrees hot water for 3d, with a weight loss rate of 95%, and degrades after 5d with rate close to 100%
Utilize the heat resistance of biodegradable materials:
Success Story: CPLA Disposable Coffee Cup Lid
Performance matching:
1. Heat resistant to 100 degrees, can withstand the temperature of hot coffee;
2. High strength, can play a sealing role;
3. Can be composted together with the coated paper cup
Utilize the flexibility of biodegradable materials:
Successful case: PBAT garbage bag
Performance matching:
1. It is puncture-resistant and can hold all kinds of garbage;
2. It has good flexibility and strong bearing capacity;
3. It can be composted with kitchen waste
Utilize the low melting point of biodegradable materials:
Successful case: PCL 3D printing pen
Performance matching:
1. Low temperature welding, safe and not scalded
2. Good flexibility and easy to shape
Utilize the barrier property of biodegradable materials:
Successful case: PGA/PPC food packing film
Performance matching:
1. Good flexibility, can play a packaging role;
2. Barrier properties can extend the shelf life of food and prevent food from expiring quickly;
3. Can be handled together with excess food
Utilize the Dimensional stability of biodegradable materials:
Successful case: PLA Desktop 3D printer consumables
Performance matching:
1. Small shrinkage, strong printing dimensional stability;
2. Low processing temperature, fast product cooling, strong interlayer adhesion;
Printing odorless
