Keruiwo's self-developed XCPS enters small-batch stable mass production, with domestic substitution

Crosslinked polystyrene (XCPS) is essentially a thermosetting polymer material that has undergone special crosslinking modification of ordinary polystyrene—but it is no longer the "foam plastic" that the public is familiar with, but a special engineering plastic born after molecular network reconstruction.

Authoritative test data shows that the dielectric constant of XCPS remains stable at approximately 2.5 across an ultra-wide frequency range of 1MHz to 500GHz.Dielectric loss factorWith a molecular weight as low as 0.0005 and a density of only about 1.05 g/cm³ (nearly 40% lighter than traditional fiberglass), it operates in temperatures ranging from −70°C to +110°C and possesses excellent radiation resistance and high-voltage breakdown resistance. This combination of "rock-solid stability across the entire frequency band" makes it a rare, well-rounded performer in the spectrum of high-frequency dielectric materials.

Currently, XCPS has been substantially implemented in several high-tech and cutting-edge sectors:

• Controlled nuclear fusion (Z-pinch route): Corevo Technology has completed the batch delivery of XCPS insulating rings with diameters ranging from 1 to 3.5 meters for use in Z-pinch large-scale continuously operating insulated reactors—the "core barrier" ensuring the high-voltage stability and safe operation of the device. Its dielectric uniformity, internal stress control, and radiation resistance life directly determine the device's availability. Currently, the development of 5.5-meter insulating rings is underway.

• In ICF inertial confinement fusion: In international ICF research, hydrocarbon (CH)-based polymer shells have been considered one of the preferred ablation layer materials for ignition targets. Compared to beryllium (Be) schemes, CH-based shells have no significant microstructural defects, are optically transparent, facilitating fuel ice layer characterization, and are non-toxic with strong controllability in preparation. XCPS, representing low-Z, high-purity cross-linked polymer systems, is being considered as the next generation of target pellets/ablation chamberKey directions in the evolution of materials.

• Microwave/millimeter-wave/terahertz and aerospace: From phased array radomes and missile guidance system insulation components to 6G high-frequency dielectric lenses and satellite antenna assemblies, XCPS is replacing some imported quartz-based/ceramic-based solutions, alleviating the passive situation of long-term reliance on foreign high-end radar dielectric materials.

Many researchers in the field of materials pointed out that the strategic value of XCPS does not lie in the ultimate crushing of a single indicator, but in the fact that the same material can simultaneously meet the set of conditions that are extremely difficult to reconcile in practice: "extremely wideband low-loss wave transmission + radiation resistance and pressure resistance + lightweight and easy processing + low cost and mass production" - which is the real pain point in the design of high-end equipment.

In the context of current geopolitical technological competition, the practical implications of this attribute are particularly clear:

• Firstly, it addresses bottlenecks by replacing outdated technologies. Compared to international benchmarks such as the US Rexolite (registered:1422), XCPS has achieved comparable dielectric stability and radiation reliability. Moreover, by leveraging domestically sourced raw materials and manufacturing processes, it has transformed supply chain risks from "external dependence" to "self-control."

• Secondly, there is the cross-domain leverage effect. A basic material can simultaneously serve communications (6G/satellite), energy (ICF/fusion), aerospace (radome/guidance), and defense (precision microwave engineering), which is a typical example of the multiplier effect of "basic materials empowering high-end manufacturing".

• Third, its role as a foundation for future technologies. Whether it's the terahertz dielectric requirements of 6G or the insulation material requirements under extreme conditions of fusion energy experimental devices, XCPS has entered the list of core material candidates—it is not a "component" for a particular project, but an enabling factor for the entire technological route.

The market expectation of tens of billions of dollars confirms the enormous potential of Corevo Technology's cross-linked polystyrene XCPS in the nuclear fusion era. However, in the field of ICF pellets, moving from "usable" to "easy to use" still requires overcoming the "triple hurdles" of homogeneous cross-linking, extreme purification, and precision molding. This is not only a contest of technology, but also a touchstone for engineering toughness.

Today, with KREVO Technology taking the lead in achieving stable small-batch production of cross-linked polystyrene (XCPS) and realizing mass delivery of multi-size insulating rings along the Z-pinch route, the competitive logic of high-end polymer materials has changed: it's no longer about who has the most impressive specifications, but about who can provide a continuous, safe, and reliable supply. In this long race concerning the future of national energy, cross-linked polystyrene (XCPS) has completed the most difficult initial stage and is accelerating towards the next strategic high ground.
