WebMar 8, 2016 · Others pointed out more technical reasons why they lean toward “Resin”: “Although the term resin evokes thoughts of plant ‘ooze’ such as amber, it is a much more practical term to use in the plastics industry versus polymer. Polymer describes the material at a macromolecular level whereas resin describes the material in bulk form.”. WebLipids are not usually polymers and are smaller than the other three, so they are not considered macromolecules by some sources 1, 2 ^{1,2} 1, 2 start superscript, 1, comma, 2, end superscript.
