Good news! Keliwo Technology was recognized as a Guangdong Provincial Famous and Excellent High-Tech

Recently, the Guangdong Provincial High-Tech Enterprise Association officially announced the evaluation results. After rigorous processes including independent application, expert evaluation, and review verification, Keruiwo Technology,凭借 its “high-performance large-diameter cross-linked polystyrene annular insulation material”, successfully won the title of “Guangdong Provincial Famous and Excellent High-Tech Product”.

The award-winning product is a large-diameter annular insulation device developed by Keruiwo Technology based on its independently developed XCPS® cross-linked polystyrene material. Cross-linked polystyrene is a thermosetting special engineering plastic obtained by special cross-linking modification of ordinary polystyrene. XCPS maintains a stable dielectric constant of 2.5 across an ultra-wide frequency range from 1 MHz to 500 GHz, with a dielectric loss as low as 0.0005, a density of approximately 1.05 g/cm³, a breakdown strength >50 kV/mm, and an operating temperature range covering −70°C to +110°C. It combines characteristics such as low dielectric constant, low loss, lightweight, radiation resistance, and high-voltage breakdown resistance, and is regarded by the industry as a domestic alternative to the American Rexolite® 1422.

"Large diameter" is the key label of this product. Keruiwo has achieved batch delivery of XCPS insulation rings with diameters ranging from 1 to 3.5 meters for the controlled nuclear fusion Z-pinch route, used in large-scale continuously operating insulation stacks—the core barrier ensuring 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 team has initiated the development of 5.5-meter ultra-large insulation rings, continuing to push towards the size limit.

Behind the honor lies the years of dedication of Keruiwo's R&D team. The team has overcome key processes such as raw material purification, "zero initiator" preparation, and precise polymerization of large-sized multi-temperature zones, achieving full-chain localization from formulation to preparation, and solving engineering challenges such as uniformity of large-sized products, internal stress control, and overall structural stability.

In addition to serving controlled nuclear fusion, the product has also been extended to "bottleneck" scenarios such as ICF inertial confinement fusion target materials, phased array radar radomes, 6G high-frequency dielectric lenses, and satellite antenna components.

This recognition as a Guangdong Provincial Famous and Excellent High-Tech Product is a strong testament to this technological strength. The award is led by the Guangdong Provincial High-Tech Enterprise Association, aiming to select benchmark products with leading technology and high market recognition. Keruiwo's selection not only serves as an authoritative endorsement of product performance but also highlights Guangdong's hardcore independent innovation strength in the field of high-end special materials.

Honors are milestones, but also bugles for departure. Looking to the future, Keruiwo Technology will continue to anchor the development goal of 5.5-meter ultra-large insulation rings, expanding the application boundaries of “super plastic” through continuous technological iteration. We will continue to uphold the spirit of independent innovation, enabling more “hidden champion” products to serve deep space, deep sea, and cutting-edge big science projects, contributing solid material strength to Guangdong's efforts in building a technological innovation highland.
