New deflashing system from CSI makes cryogenic pretreatment redundant
The new macrofinishing machine MF-15L from C.S.I. Centro Servizi Industriali removes runner and overflow flashing from injection molded elastomer parts in an automated process that does not require any prior cooling of the parts in liquid nitrogen. This process reduces energy consumption, thus making a significant contribution to the protection of the environment and cutting production costs.

Evolution of silica to the sustainable Nzerosil series from renewable rice husk
One current goal of the tire industry is to replace all oil derived materials with sustainable products derived from renewable biomass sources. Silica can be directly obtained from eco-friendly sustainable materials of bio-origin, including rice husk (hull) and rice straw (dried leaf), cornflower, sorghum (grass flowers) and bagasse (sugar cane)

Sustainable materials for rubber and allied industries
Sustainability is no longer a new concept; it has become a global priority. While quality was the focus of the 1980s, globalization defined the 1990s, and the internet revolutionized the 2000s. The 2010s and after have been dominated by the idea of sustainability. Human survival depends on integrating sustainable practices into every aspect of life. The world is already witnessing alarming environmental changes: rising greenhouse gas emissions, depletion of non-renewable resources and widespread deforestation.

FDA approved low PAH thermal carbon black to meet regulatory requirements
Regulatory requirements targeted at polycyclic aromatic hydrocarbon (PAH) content in consumer rubber goods are becoming increasingly common. Developments in the formulations and raw materials used can help minimize the PAH content as needed to meet these requirements. Testing was completed comparing thermal carbon black Thermax N990 to Cancarb’s FDA approved, low PAH Thermax N990CG in a wide range of rubber compounds.

Penn State researchers develop high temperature polymer capacitor
In the race to lighter, safer and more efficient electronics — from electric vehicles to transcontinental energy grids — one component literally holds the power: the polymer capacitor. Seen in such applications as medical defibrillators, polymer capacitors are responsible for quick bursts of energy and stabilizing power rather than holding large amounts of energy, as opposed to the slower, steadier energy of a battery. However, current state-of-the-art polymer capacitors cannot survive beyond 212 degrees Fahrenheit (F), which the air around a typical car engine can hit during summer months and an overworked data center can surpass on any given day.
