1. Introduction: The “Crown Jewel” of Organosilicon Chemistry While the world is familiar with silicones (polysiloxanes) containing Si-O bonds, a unique and powerful class of materials has emerged: Polysilazanes (PSZ). Characterized by a Si-N (Silicon-Nitrogen) backbone, these polymers are notoriously reactive and difficult to synthesize, yet they offer performance properties unmatched by traditional silicones. A […]
In the world of elastomer engineering, standard silicone (VMQ) is a workhorse. It serves us well in daily life, from kitchenware to basic sealing. However, for R&D engineers designing for the aerospace, heavy industry, or advanced electronics sectors, “standard” often translates to “failure point.” When applications demand performance outside the typical -40°C to +200°C window, or […]
The Engineering Challenge: Speed vs. Quality In the manufacturing of High-Consistency Rubber (HCR) and Phenyl Silicone components, the vulcanization (curing) phase is often the bottleneck of production. It presents a classic engineering trade-off: Low-temperature curing yields superior physical properties and cross-linking density but slows down production. High-speed curing increases throughput but risks defects like scorching, bubbles, or […]
1. Industry Background: Evolution of Elastic Putty Dampers Research into elastic putty–based viscoelastic damping materials began in the 1960s, with early development led by European research institutes. By the 1980s, elastic putty damper technology had matured and entered industrial deployment in several European countries. Today, Poland, Russia, France, and the United States are among the […]
Industry Background: From Early Research to Industrial Deployment Research into elastic putty–based damping materials began in the 1960s, with early development led by European research institutions. By the 1980s, the technology had reached industrial maturity in several European countries. Since then, countries including Poland, Russia, France, and the United States have developed their own high-performance […]
Silicone rubber has become the preferred elastomer for applications where durability, safety, and temperature resistance are non-negotiable. From industrial seals and vibration dampers to automotive and medical components, silicone rubber is replacing conventional plastics and rubbers at an accelerating pace. However, one recurring issue continues to concern both procurement managers and R&D engineers: silicone rubber […]
The draft gear (buffer) is a critical component of rail transit vehicles. Its function is to mitigate longitudinal impulses and vibrations caused by changes in locomotive traction force or by collisions between vehicles during starting, braking, and shunting operations. It directly impacts key technical and economic indicators regarding railway transport efficiency, such as total traction […]
Hydraulic oil, metal springs, and rubber are the three most commonly used media for buffering and vibration damping. Products based on these materials are generally referred to as shock absorbers or dampers. Hydraulic dampers use hydraulic oil as the energy-absorbing medium. Under external load, energy is dissipated through viscous flow and frictional heat generation. However, […]
Policy update will increase export costs for silicone supply chains The Ministry of Finance of the People’s Republic of China and the State Taxation Administration have jointly issued the Announcement on Adjusting Export Tax Rebate Policies for Photovoltaic and Related Products. According to the announcement, export VAT rebates for photovoltaic products and selected chemical materials […]
