l Optimized for Direct-to-Chip Liquid Cooling (DLC), delivering
breakthrough performance over conventional air cooling

l Earns OCP “Inspired” supplier qualification — first in Korea and second
worldwide — validating competitiveness and accelerating global expansion

l Formulated with SK picglobal’s flagship propylene glycol (PG), meeting
human safety standards and offering biodegradability

SK picglobal,
an SKC-invested chemical business, has launched HTF (Heat Transfer Fluid) PG25,
an eco-friendly cooling fluid engineered for AI data centers. HTF PG25 is optimized
for Direct-to-Chip Liquid Cooling (DLC), which directly cools high-temperature
components such as GPUs and CPUs inside servers.

DLC,
the target application for HTF PG25, is emerging as a key technology for AI
data centers and can deliver up to 10× higher cooling efficiency than
conventional air cooling. As global IT leaders including NVIDIA adopt DLC as a
next-generation data center standard, the technology is gaining traction as an
essential solution for high-density servers.

Following its launch, HTF PG25 became the first in Korea — and only the
second worldwide among DLC cooling fluids—to earn the Open Compute Project (OCP)
“Inspired” supplier qualification. OCP is a global consortium that promotes
open collaboration across semiconductor silicon, servers, networking, and data-center
infrastructure. An increasing number of data-center operators now require OCP-qualified
solutions from their suppliers.

Environmental
performance is another key strength of HTF PG25. The product uses SK picglobal’s
high-purity propylene glycol (PG), a material widely validated for safe use. It
is formulated with propylene glycol that meets United States Pharmacopeia (USP)
specifications, supporting both human safety and biodegradability.

Building on
the launch, SK picglobal is accelerating its expansion into the AI data-center
cooling market. The company began commercial sales in Korea in October and
plans to broaden collaboration with data-center operators and solution
providers in Korea and overseas, delivering sustainable and cost-efficient
cooling solutions worldwide.

An SK
picglobal spokesperson said, “HTF PG25 will help improve energy efficiency in
data centers and reduce carbon emissions. With commercial sales underway in
Korean since October and our OCP “inspired” supplier qualification, we aim to
deliver trusted cooling solutions to customers in global markets.”[End]
