Benzocyclobutene (BCB) is an organic compound with a rigid molecular structure composed of a conjugated benzene ring and a four-membered ring. Its excellent thermal stability and electrical properties have made it a highly promising candidate for next-generation electronic materials. Historically, its industrial adoption has been constrained by high production costs, complex purification processes, and limited output. However, with growing demand in high-end applications and recent advances in upstream technology, BCB is now poised for industrial-scale deployment. Material Properties and Structural Advantages BCB (C₈H₈) is a non-polar molecule, free of ester, carboxyl, or amide groups, giving it excellent dielectric properties and low moisture absorption. Its dielectric constant (Dk) and dissipation factor (Df) remain stable across wide temperature and frequency ranges—key metrics for ensuring signal integrity in high-frequency, high-speed communication systems. Unlike conventional m...

As global energy exploration continues to advance into deeper, hotter, more saline, and higher-pressure formations, the performance requirements for oilfield cementing additives have become increasingly stringent. In particular, in challenging environments such as the Middle East, Central Asia, North America, and offshore oilfields, cementing additives with excellent fluid loss control, retardation, anti-settling, and environmental adaptability have become critical to ensuring wellbore integrity and enhancing operational efficiency. At the same time, the global trend toward environmentally sustainable operations has accelerated the demand for phosphate-free preflushes and low-toxicity defoamers in international markets. Against this backdrop, Polyberg leverages its deep expertise in polymer chemistry and engineering to deliver high-performance, tailor-made cementing additive solutions for the global energy industry. Its products are already in use across a wide range of internationall...
