Sealing solutions offered for air and sea

In aerospace, demand has increased for actuator designs that meet and exceed more rigorous performance standards, while providing unprecedented safety and reliability. Some of these requirements, such as the fire and flammability resistance defined in ISO 2685 and RTCA DO-160, go beyond the use of standard hydraulic seal designs. These high temperature, challenging requirements significantly impact commercial aircraft engine safety, and often force the use of heavy, bulky, easily damaged and costly external fire shielding. As a result, Greene Tweed developed the Fireproof Hydraulic Seal (FPH Seal), which has been specifically engineered to meet this need and establish a shielding alternative.

The case for reintroducing latex surgical and exam glove production back into the U.S.

The world today uses 12,000 medical gloves per second. Prior to the UP publication, U.S. glove production had been satisfied by a number of medical device manufacturers, namely, Safeskin, Ansell, Aladan, Baxter, Smith & Nephew and Johnson & Johnson. In addition, glove imports in the U.S. prior to 1985 were 1 billion pieces. In 1996, imports exceeded 21 billion pieces.

Use of Tire-Derived and Scrap-Derived Polymers in Tire and Non-Tire Applications

The disposal of scrap rubber has been a concern since its vulcanization with sulfur and heat was accidentally discovered by Charles Goodyear in 1839. In addition to the scrap generated in production, there is the question of discarded rubber goods that have outlived their usefulness for their original function. Traditionally, this waste had ended up in landfills, contributing to the growing problem of overcrowding. Scrap tires are a well-publicized category of scrap rubber, as each year automobiles produce 246 million waste tires in the United States alone.

Synthesis of reduced graphene oxide/clay nanohybrid: Efficient adsorbent for CO2 and flame retardant

Research shows the development of a graphene/clay hybrid which is an eco-friendly material with air purification capability, and which can also serve as a flame retardant additive in polymers. Two-dimensional nanomaterials like layered silicates, graphene and layered hydroxides (LDH) have been widely studied due to their high aspect ratio, which in turn enhances properties like flame resistance, mechanical properties, gas adsorption, barrier properties and water purification.
