Nan Pao joint venture nears full capacity as semiconductor demand rises

Nan Pao’s joint venture targeting advanced encapsulants is a direct response to surging demand from Chiplet and HBM packaging. This move pressures upstream epoxy and siloxane suppliers to accelerate purity upgrades while forcing OSATs to shorten material compatibility validation cycles. Although the JV structure partially circumvents U.S.-led export controls, inclusion of packaging materials under expanded entity list restrictions could spike compliance costs by over 30%. Japanese rivals like Sumitomo Bakelite will likely fast-track Southeast Asian or Indian production, while Korean players may leverage Samsung and SK Hynix’s vertical integration. Within 18 months, advanced packaging materials will emerge as a new geopolitical battleground—China’s domestic substitution push will intensify, yet high-purity monomer synthesis remains a critical bottleneck.
