The VersaDamp(TM)200 Series of damped TPE materials eliminates the need to make tradeoffs in damping and operating temperature ranges. The materials feature durometers ranging from 40 to 75 Shore A, and they are reported to have widely varying energy control capabilities as well. Designed to be easily injection-molded into isolators, they are recommended for anti-shock and anti-vibration mounts for compactly designed devices with limited isolator sway space.

Providing virtually non-toxic and non-combustible coatings for interiors and exteriors of hazardous material storage buildings, this environmental system utilizes an inorganic silicon-oxygen material that is more heat stable, up to 2,000F, when compared to the epoxies or polyurethanes, which are limited to 200-250F. The inorganic material is unaffected by sunlight and ultraviolet rays, is corrosion and thermal resistant, and may be used for topcoats, tank linings, surfaces, and antifoulings.

VOC-free composite molding
Composite Solutions, a line of thermoplastic polymers designed as VOC-free replacements for thermoset polyester, epoxy, and urethane molding compounds, can be formed using low-cost tooling and consolidated without expensive autoclave equipment. They are available as PolyPly(TM), an aqueous emulsion of modified acrylic, styrenic, and urethane polymers; and PlyoForm(TM)prepregs, which are fibers impregnated with PolyPly resins.

Intended for use as a pigment treatment, the company's 3 Additive is designed to aid dispersion in paint and coatings, and also helps formulators improve leveling, flow-out, wetting, and gloss. A water-clear liquid supplied at 10% solids in a toluene carrier, it's usually added during the final thinning and color-matching step. At 25C, the material has a specific gravity of 0.888 and a viscosity of 1 cs.

Lubriloy(R), for applications that need both conductivity and lubrication that can't tolerate contamination or corrosion, avoids the use of fluorine-containing compounds that can get back into the media and corrupt it. This is especially a problem with electronic devices that have been getting smaller and smaller, thereby reducing the amount of free airspace that would allow natural escape of the compounds. Costly post-molding operations such as baking or washing to drive off the volatiles can then be avoided.
