Trelleborg Sealing Solutions has a new sealing material engineered for automated assembly of products used in potable water applications

The ethylene propylene diene rubber compound,Turel E7Y30 has been engineered to meet global potable water regulations NSF/ANSI 61 and to provide effective, automated assembly of seals, the company said.

Trelleborg said Turel E7Y30, with a hardness of 70 durometers, avoids the potential issue of high elongation in automated assembly processes and provides reduced friction, which leads to reduced abrasive wear and increased life. According to the company, the material has been tested and approved for joining and sealing materials that come into contact with drinking water, meeting global regulation NSF/ANSI 61 Section 6. It has also been tested and approved for installation in end-point devices intended to dispense water for human ingestion (NSF/ANSI 61 Section 9), Trelleborg said.

Turel E7Y30 can be used in products manufactured using automated assembly methods in end-use potable water applications such as faucets, valves, water heaters, ice makers, pumps, filters, meters, and fittings, according to the firm. The compound resists chloramine and chlorine and can be supplied in various seal types, such as o-Rings, square rings, and gaskets, Trelleborg claims.

Grieve Corp. has released a 500°F (260°C), inert atmosphere oven used for aging rubber parts.

The oven, No. 870, measures 36 inches wide x 60 inches deep x 36 high, the company said. Twelve kilowatts are installed in sheathed tubular heating elements, while a 600 CFM, one-half horsepower recirculating blower provides airflow to the workload, according to Grieve.

The company said the inert atmosphere oven has 4 inches of insulated walls, an aluminized steel exterior and Type 430 stainless steel interior. The oven features inert atmosphere construction, including a pressure regulator, flow meter, pressure gauge, inner oven walls that seal against one-inch thick silicone rubber seal, air jacket on the inner oven for cooling, blower shaft seal, latching door hardware and adjustable offset door hinges. The company also said the oven provides an outlet with pressure relief, interior seams welded gas-tight and all wall penetrations fitted with compression fittings.

Grieve said the oven has a 650 CFM blower with two-position motorized dampers to pull air through the air jacket on the inner oven for cooling. The oven has a programmable temperature controller, the company said.

Quantum Silicones L.L.C. has unveiled its True Skin series, which features a selection of three Shore A hardnesses: 10, 20 and 30. The company said all three grades are two-part, addition (platinum) cure silicones.

True Skin silicones are customizable for creating prosthetics and special effects props, the company claims.

Acccording to QSi, the translucent True Skin 10, True Skin 20 and True Skin 30 have a 1:1 mix ratio and are convenient to weigh and mix the base with the catalyst. They are pigmentable, the company said, adding color effects to the silicone, or matching individual skin tones. Pigments can be added after mixing the base and the catalyst. As long as both parts remain at a 1:1 ratio, pigments can be mixed into either part, the company said. Silicone paints using pigments can be painted onto a platinum cured silicone part as well, QSi said.

Diluent fluid can be added to the True Skin silicones to create a softer, more pliable silicone while maintaining durability, the company said. Adding diluent fluid will lower the silicone's durometer and viscosity, according to QSi, and the diluted silicone makes it possible to apply in thin sections. Diluent fluid can be added up to 30 percent and will cure with minimum fluid bleed out, the company said.

The low viscosity silicones can be dispensed from 50 milliliter and 400 milliliter cartridges, the company said, eliminating the need to de-air the silicone.

QSi said True Skin silicones all have a “knotty tear” that will not continue to propagate through in a straight line, helping to prolong the life of the silicone part or mold.
