Break the foreign monopoly! Why has XCPS cross - linked polystyrene material become the "new domesti

In the millimeter wave antennas of 5G base stations, in the sonar lenses of deep-sea detectors, and in the microwave components of satellite navigation, these core components that support modern technology have long been strangled by a "neck-choking" material: special polymer materials monopolized by foreign countries are not only expensive, but also may be out of supply at any time. Today, Corevo Technology's XCPS cross-linked polystyrene material is making a strong breakthrough, rewriting the global microwave material landscape with "Made in China".

Some materials for microwave components in my country rely on imports. Take the microwave lenses in satellite communication equipment as an example. In the past, the imported Rexolite1422 material not only had a procurement cycle of more than 3 months, but also had key parameters restricted by foreign technical standards. The Corevo R&D team targeted this pain point and, after many rounds of formula debugging and performance verification, finally succeeded in pilot mass production of XCPS cross-linked polystyrene materials. Its dielectric constant (2.5) and dielectric loss factor (0.0005) are completely comparable to the international leading material Rexolite1422 in the 1MHz-500GHz frequency band, and some indicators are even better, completely breaking the foreign technology blockade.

The "hard core" of XCPS cross-linked polystyrene is hidden in every set of data: it is an optically transparent thermosetting plastic, but it has metal-like rigidity and can be processed with an accuracy of up to IT0 level; in the field of aerospace, the radar antenna cover made of XCPS cross-linked polystyrene material carried by a certain type of drone is not only lighter than traditional metal, but also has extremely low signal loss, which significantly improves the drone's ground detection distance; in the construction of 5G base stations, high-frequency coaxial connectors made of XCPS cross-linked polystyrene material are used to reduce signal transmission loss. What is more noteworthy is its "anti-forging" characteristics: the breakdown strength is >50kV/mm, and the performance is stable in the space radiation environment. Even the ultrasonic wedges in the medical field have begun to use it to replace traditional materials, which improves the clarity of B-ultrasound imaging.

As the international situation becomes increasingly volatile, independent and controllable materials have become a "must-answer question" in scientific and technological competition. The outbreak of XCPS cross-linked polystyrene is timely: on the one hand, the country's "14th Five-Year Plan" new materials plan clearly supports the localization of high-end polymer materials, and local governments provide tax incentives and R&D subsidies to material companies; on the other hand, the localized production of XCPS cross-linked polystyrene has shortened the delivery cycle from 3 months to 20 days, and some conventional models are available for immediate delivery, reducing the overall cost by 30%. The head of a leading communications equipment company admitted: "In the past, when we used imported materials, we had to look at the faces of foreign suppliers when customers urged for delivery; now we use Corevo's XCPS cross-linked polystyrene, not only is the delivery time controllable, but it can also be customized according to demand, and customers are actively placing orders."

From the laboratory to the production line, from "following" to "leading", XCPS cross-linked polystyrene materials not only solved the "bottleneck" dilemma of microwave components, but also injected strong momentum into cutting-edge fields such as 5G, 6G, unmanned driving, and deep space exploration with the strength of "Chinese materials". When "domestic substitution" is no longer a slogan, Corevo has proved with its strength that China's high-end materials can support the backbone of scientific and technological self-reliance.
