Silicone rubber recycling plant completes phase one

The first silicone rubber recycling plant in the U.S. has completed phase one of development. Started in 2018, ECO USA’s pilot facility has undergone tremendous growth. It can currently recycle approximately 500 metric tons of silicone monthly, with plans for reaching 1,000 metric tons in the near future. The success comes at a pivotal moment when a surge of silicone waste is being observed as a result of the increase of silicone usage in product manufacturing

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.

Nickel-aluminum fluorosilicone meets EMI specs

Nickel-aluminum fluorosilicone that combines EMI shielding with fuel, solvent and galvanic corrosion resistance, has been independently tested to 40 GHz and can be used with military electronic products that need to meet MIL-DTL-461 5.18 RE103 requirements for controlling electromagnetic interference (EMI). SSP’s EMI fluorosilicone has also been independently tested to MIL-DTL-83528 for elastomeric shielding gaskets, and to ASTM E595 for outgassing.

Keltan 2470E EPDM Grade for Excellent Electrical Performance in Wire and Cable

Ethylene propylene diene polymers (EPDM) are the most widely used rubbers in the range of available synthetic rubbers for non-tire applications. Due to the unsaturated backbone, EPDM can be employed in various applications in which characteristics such as resistance to ozone, heat and moisture, flexibility at low temperatures, a wide range of tensile strength and hardness levels, and excellent electrical insulating properties are important

Simultaneous Effects of Mixing Parameters on Internal Mixing of Rubber and Carbon Black Using Response Surface Methodology

In order to investigate all the effects of the processing parameters on the mixing properties without having to do a number of experiments, the statistical tool, called response surface methodology (RSM), has been used. This technique has the capability to evaluate all the effects of the parameters on the responses, which include linear, non-linear and interaction effects. Simultaneous Effects of Mixing Parameters on Internal Mixing of Rubber and Carbon Black Using Response Surface Methodology

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.

Lamination technology for multi-layer hose

Fluoroelastomer lamination technology for multilayer automotive hose constructions is said to be ideal for use in high-pressure, high-temperature areas near the engine, where they are also exposed to NOx, SOx, engine oils or other aggressive automotive fluids. AGC Chemicals Americas՚ AFLAS FEPM fluoroelastomers can withstand continuous service temperatures up to 200°C and have excellent acid, base, amine and steam resistance.

Thermally conductive elastomer for EV parts

Freudenberg Sealing Technologies (FST) has developed a thermally conductive elastomer that combines seemingly contradictory properties: It conducts heat well, but is also electrically insulating. FST is already testing initial applications for charging sockets, control units and batteries in electric vehicles.
