SBS Polymer Asphalt Modifier

Inventor and leading maker of styrenic block copolymers (SBS/SIS); also a pine-chemicals business. ~18% global SBS share. Acquired by DL Holdings (DL Chemical, South Korea) in 2022.

Chinese state petrochemical company (SSE/HKEx: 600028 / 0386, HQ Beijing). China's largest refiner and the world's second-largest refiner by capacity. Sinopec produces hexane at multiple refineries including Yanshan (Beijing), Maoming (Guangdong), and Zhenhai (Zhejiang) as part of naphtha fractionation. China is now largely self-sufficient in hexane supply through Sinopec and PetroChina, having reduced import dependence via domestic refinery expansion. Sinopec supplies hexane to China's domestic soybean crushing industry (China is the world's largest soybean crusher, processing ~95 million tonnes/year) — an enormous captive hexane market. Sinopec's hexane capacity is embedded in China's strategic plan for food oil self-sufficiency.

Taiwan Synthetic Rubber Corp — major Asian SBS/SIS/SEBS producer; plants in Taiwan, China, India, USA (via Dexco).

Synthetic rubber/SBS producer; historically a 50/50 JV between Repsol (Spain) and Grupo KUO (Mexico). Plants in Spain, Mexico, China.

Taiwanese chemical company (HQ Taipei); the only vertically integrated electronic-grade IPA (EIPA) manufacturer in Taiwan and one of only two global suppliers of EIPA for the semiconductor industry. LCY's EIPA achieves 99.999% purity at PPT (parts-per-trillion) impurity levels, meeting specifications for sub-5nm IC fabrication, TFT-LCD, LED, and PV industries. LCY is described by industry sources as 'one of the two EIPA suppliers for the semiconductor industry' — making it effectively a duopoly with Tokuyama for the most critical semiconductor-grade IPA. Taiwan's domestic semiconductor production (TSMC, UMC, ASE) relies heavily on LCY for cleaning solvents. An obscure Taiwanese chemical company holds semiconductor supply chain leverage comparable to ASML or BASF in their respective domains.

South Korean chemical conglomerate (KRX: 051910, HQ Seoul); major producer of electronic-grade IPA for the semiconductor industry with strategic partnerships with major tech manufacturers. LG Chem supplies IPA to Asian semiconductor fabs and has significant presence in the Korean and broader Asian electronic chemicals market. Same company that is the world's #2 EV battery maker (LG Energy Solution is a spin-off) — LG Chem bridges the semiconductor chemicals market and the EV battery materials market. Also produces NMC cathode active materials for batteries, ABS resins, and engineering plastics.

Eni's chemical subsidiary; major European SSBR and ESBR producer. Primary production at Porto Torres (Sardinia) and Ravenna (Emilia-Romagna). Supplies European tire manufacturers (Pirelli, Continental, Michelin). Eni is divesting Versalis to Ineos (announced 2024, Versalis to become part of Ineos Inovyn). ~5-6% estimated global SSBR market share.
