It is made from lactic acid and ethanol as the source materials.
The forms and biological characteristics of these materials are slightly different.
Suture Materials.
However, the fundamental problem is derived from suture-thread materials.

In the study of composite materials, the matrix is the component that binds the filler particles to form the new material.
Reinforcing materials are a form of fillers, they are added into the matrix of the parent material to enhance its mechanical properties.
As such, polymeric composite materials have been a competitive alternative to typical metallic and alloy materials such as aluminum and steel [13].

Viscoelastic materials are used in automobiles and other products.
However, because of theoretical complexity, it has not been easy to put all the energy exhausted into the automotive viscoelastic materials.
This response is found in typical viscoelastic materials.

They are no longer ideal structural materials for greenhouse frame.
Thus it can be conceived that traditional scaffolding structural materials can be replaced by an existing polymer organic materials.
And with a wealth of material model library, it can be used to simulate the majority of common engineering materials such as metals, polymers, composites, rubber, resilient compressible foam, reinforced concrete and other geological materials.
Therefore, it is feasible to use new polymer materials instead of traditional greenhouses structural materials.

There is no correlation in BK 8 as 222Rn concentration is found to be independence to the environmental factors. 222Rn concentration in BK 8 could be influenced by building materials, ventilations and weathers.
