The characteristics of the main types of biopolymers.

PolymerCharacteristicProduction volume, tonsDegradation time

NonbiodegradablePE (polyethylene)
Transparent, plastic, dielectric, shock-resistant, low gas and vapor permeability, physiologically neutral, softens when heated (80–120°С), odorless.248980100–200 years
PET (polyethylene terephthalate)
Amorphous, dielectric, shock-resistant, not resistant to UV radiation.206780150 years
PA (polyamide) [-NH-(CH2)6-NH-CO-(CH2)8-CO-]nDurable, heat-resistant, chemical resistant, abrasion resistant.244760100 years
PP (polypropylene)
High strength, low density, resistance to shocks and repeated bends, high chemical resistance, low gas and vapor permeability18990At least 500 years old
PTT (polytrimethylene terephthalate)
Crystal, durable, wear-resistant.194120At least 100 years old

BiodegradablePBAT (polybutylene adipate terephthalate)
Durable, hard, solid, resistant to creep, good dielectric, vulnerable to UV radiation.282740Less than 6 months
PBS (polybutylene succinate)
High-strength, low density, resistance to impact and multiple bends, excellent electrical insulation, high chemical resistance.907305 months
PLA (polylactide)
Biologically safe, nontoxic, insoluble in alcohols and water.2932903 months
PHA (polyhydroxyalkanoates)
They are resistant to the action of hot water, at the same time they decompose quickly in natural conditions.253206 months
