noun
plastomer
Technical term in chemistry for a polymer with properties between elastomers and plastics.
プラストマーは、ゴムとプラスチックの中間的な性質を持つ材料です。
Plastomers are materials with properties intermediate between rubber and plastic.
エラストマー (elastomer) is rubber-like and highly elastic, while プラストマー is less elastic and more plastic-like.
プラスチック (plastic) is rigid and non-elastic, whereas プラストマー has some elasticity.
Borrowed from English 'plastomer', a blend of 'plastic' and 'elastomer'.
