PEL 并非通用塑料/工程塑料领域的标准缩写，结合高分子材料领域常见表述，其核心所指为 “可降解聚酯弹性体”（Polyester Elastomer），是一类兼具聚酯的刚性与弹性体柔韧性的高分子材料，核心特征是可在自然环境（如土壤、海水）中被微生物分解，属于环保型高分子材料。

和PC一样，ABS是高分子材料领域的标准通用缩写，核心所指为丙烯腈-丁二烯-苯乙烯共聚物（Acrylonitrile-Butadiene-Styrene copolymer）—— 这是一类由三种单体（丙烯腈、丁二烯、苯乙烯）共聚而成的通用工程塑料，通过调节三种单体的比例，可精准调控材料性能，是目前工业界和日常生活中应用最广泛的塑料品种之一。

不同于此前提到的PEL、PAL（非通用缩写），PC是高分子材料领域的标准通用缩写，核心所指为聚碳酸酯（Polycarbonate）—— 这是一类分子主链含重复碳酸酯基团的工程塑料，兼具优异的力学性能、透明性和耐温性，是目前应用范围极广的通用工程塑料之一。

To understand bio-based nylon, it is necessary to first clarify the basic concept: PA, short for polyamide and commonly known as nylon, is a class of high molecular compounds with repeating amide groups in the main molecular chain, and also one of the earliest engineering plastics to achieve industrial production. Distinguished from traditional petroleum-based nylon, bio-based nylon refers to an eco-friendly polymer material whose monomer feedstocks (or partial feedstocks) are derived from renewable biomass resources instead of non-renewable petroleum.

PA, short for polyamide and commonly known as nylon, is a class of high molecular compounds with repeating amide groups in the main molecular chain. It is also one of the earliest engineering plastics to achieve industrial production.

PP is a standard universal abbreviation in the polymer materials field, referring essentially to polypropylene—a thermoplastic resin polymerized from propylene monomer and categorized as a general-purpose plastic.

Similar to PEL, PAL is not a universally accepted standard abbreviation in the polymer materials field.

Similar to PEL and PAL mentioned earlier, PL is not a universally recognized standard abbreviation in the polymer materials field.

PA12, whose full name is Polyamide 12, is commonly referred to as Nylon 12. It is an important member of the polyamide (PA) family.

经过生物工程方法得到的尼龙原料经过开环聚合或者缩合聚合制备出的尼龙材料统称为生物基尼龙材料。常见的生物基尼龙材料包括尼龙11、尼龙1010、尼龙610、尼龙510、尼龙410、尼龙1012等。
