PEL is not a standard abbreviation in the field of general-purpose plastics or engineering plastics. In the context of common expressions in polymer materials, it mainly refers to "degradable polyester elastomer", a class of polymer materials that combines the rigidity of polyesters and the flexibility of elastomers. Its core feature is biodegradability by microorganisms in natural environments (e.g., soil, seawater), thus falling into the category of eco-friendly polymer materials.

In terms of core properties, PEL’s key advantages lie in the combination of degradability and elasticity. It can be prepared via the polycondensation of dibasic acids and diols. The raw materials can be either petroleum-based monomers (e.g., terephthalic acid, ethylene glycol) or bio-based monomers (e.g., bio-based ethylene glycol, bio-based adipic acid), further enhancing its sustainability. Its applications focus on fields requiring elasticity and environmental friendliness, such as degradable elastic packaging films, biomedical elastic components, and eco-friendly seals.
 

Correlations and Differences from Bio-based Nylon (Bio-based PA)

 
Both are eco-friendly polymer materials that can be produced from bio-based feedstocks. Their core differences lie in molecular structure, performance focus, and application scenarios, which can be summarized as follows:
 
  1. Molecular Structure Differences: The main chain of PEL has ester bonds as repeating units, while that of bio-based nylon has amide bonds as repeating units. This constitutes their fundamental structural difference and determines their subsequent performance variations.
  2. Performance Focus Differences: PEL is characterized by the integration of elasticity and degradability, with more outstanding flexibility and elastic recovery; bio-based nylon inherits the advantages of traditional PA, focusing on high strength and excellent wear resistance, featuring higher rigidity but relatively lower elasticity.
  3. Application Scenario Differences: PEL is suitable for eco-friendly scenarios requiring elasticity (e.g., degradable elastic packaging, biomedical elastic components); bio-based nylon is ideal for structural part scenarios requiring high strength (e.g., auto parts around engines, textile fibers, gears and bearings).
 

Supplementary Note: Review of Core Information about Bio-based Nylon

 
Bio-based nylon refers to polyamide (PA, commonly known as nylon) whose monomer feedstocks (or partial feedstocks) are derived from renewable biomass resources such as corn, sugarcane, and castor oil, distinguishing it from traditional petroleum-based nylon. Its production process is similar to that of traditional PA (polycondensation or ring-opening polymerization). It inherits PA’s excellent properties including high strength, wear resistance, and oil resistance, with its core advantages being environmental friendliness and sustainability (low carbon emissions, reduced dependence on petroleum). Common grades include bio-based PA6, PA66, and PA610, which are tailored to scenarios with different rigidity and flexibility requirements.
