What Can Weaken Plastic?
The most common cause of plastic parts to weaken is exposure of the plastic to sunlight. Plastics consist of long polymer chain molecules which are entangled together, The longer the polymer chains, the stronger the plastic. Most plastics degrade by oxidation when exposed to sunlight and heat
What Can Dissolve Plastic?
Tetrahydrofuran (THF) is co the most universal and common solvent for many plastics. However, each plastic has its own solubility properties. Amorphous (non-crystalline) plastics (for example, polystyrene and polycarbonate) are more soluble in common organic solvents. However, even THF will not
How Does Plastic Decompose?
Plastics consist of long chain molecules. The links that form the chain determine how the plastic decomposes. There are many ways that plastics decompose including oxidation, hydrolysis, and pyrolysis (heating the plastic to very high temperature causing the polymer chains to unzip back to monomer).
