Как правильно перевести "смолу пиролиза"?

Упоминается в одной новости: "производство смолы пиролиза и фракции С9 вырастет ..." и т.п.

Я почитал немного.. кажется, pyrolysis resin - это "калька".
Возможно, petroleum resin \ petroleum hydrocarbon resin - более верные варианты перевода. В определениях этих терминов указывается cracking (пиролиз).

Petroleum resin: A resin made from olefins which are derived from petroleum by cracking.

2000, V. Dragutan, ‎R. Streck, "Catalytic Polymerization of Cycloolefins ..." , page 1146
Petroleum resins are low molecular weight, thermoplastic hydrocarbon polymers manufactured from cracked petroleum fractions. ... The raw materials for petroleum resins come from the deep cracking of petroleum distillates and usually exhibit wide boiling range.
...
Three main streams from cracking of petroleum distillates are employed as crude feeds for the resin production
1. C4-C6 aliphatic stream
2. C8-C10 aromatic stream
3. dicyclopentadiene stream
