E and K Products

The company has developed a material composed of a mixture of polyurethane and treated, recycled tire rubber granules. The company believes that by combining polyurethane with rubber it is able to create a composite that retains the unique characteristics of the combined materials, including the versatility of polyurethane and the resilience of rubber. We believe that this technology has potential commercial application for solid and foam polyurethane-based products, including non-pneumatic bicycle and industrial tires and soles for footwear, and may provide cost efficiencies and enhanced product performance.

2. Water, chlorofluorocarbons and materials related to chlorofluorocarbons (eg.141b blowing agent) have traditionally been used as blowing agents, which cause polyurethane to be produced as a foam, as required in many of the material's major commercial applications. Water is often unsuitable for applications that require a smooth skin on the molded polyurethane part, and increasingly strict environmental regulations require, since January 1, 1994, that neither chlorofluorocarbons nor related ozone-depleting chemicals be used in products marketed in the United States, with certain exceptions. In addition to E&K's line of water-blown polyurethane systems for integral-skin foam, we have a separate series of polyurethane systems that use a non-ozone-depleting blowing agent (HFC-245fa).

The Americans with Disabilities Act ("ADA") and implementing regulations require that "detectable warnings" be installed in a number of locations where visually impaired pedestrians may enter a potentially dangerous vehicular area. Similar requirements have been included in the California edition of the Uniform Building Code. The detectable warnings required by regulation are surfaces with a specified pattern of truncated domes, perceptible by touch of foot or by cane. E&K's developed elastomers for detectable warning, which meets the requirements of the regulations under the ADA. The principal market for the same as these products at present is for platform edge warnings in the rail transportation industry. Such detectable warnings are also sold for sue at curb ramps and other locations. blowing agent (HFC-245fa).

E&K has developed polyurethane, polyurea and Pu hybrid systems, which are percolated over open graded aggregates to form flexible polymer concrete for repair of potholes, cracks, spalls, dips and moving joints. Overlays are formed to match grades, eliminated birdbaths, and restore a smooth riding surface for pavements damage by cracks, freeze/thaw spalling, caused by vehicle fires and rapid runway repair. Repairs withstand vibration, heavy loads, and thermal movements. These systems are rapid curing within 2-3 minutes and are self-leveling. Traffic can be resumed within 10 minutes. These systems will adhere to concrete, steel, wood, and asphalt concrete pavement.

E&K offers a technology of puncture free tires, which is a reliable, low maintenance way to avoid unexpected and often dangerous, blowouts on vehicular roadways. These polyurethane tires have advantages of being maintenance free, puncture proof, low rolling resistance, long wearing, easy to install, low weight, safer and cost effective. These wheels match the performance of pneumatics. China is the world's bicycle capital and there is a great business opportunity with no-more-flat polyurethane tires in the world.

E&K has developed single component urethane systems with a broad range of hardness. These are very stable at room temperature with long shelf life. The curing reaction of the system is initiated when temperatures (120-140 C) are sufficient to cause the blocked prepolymer to dissociate to regenerate the reactive isocyanate group. The largest use is for rollers for numerous end uses. Useful functions are: 1) rollers for paint, coating, inks, wax, adhesives and material transfer, 2) pads and dies for metal forming and flexible molds, 3) O rings, gaskets check balls, pipe line pigs, valve seats and bushing.

Tire filling with soft polyurethane elastomer is a process for converting virtually any pneumatic tire to a solid tire. E&K's two-component, equal-volume polyurethane system cures and provide good mechanical properties to withstand sharp impacts, sustain severe cuts without breakdown and improved ride. This system is pumped into pneumatic tires through the valve stem to replace all of the air to form solid tires. This filled tire can be used on any automobile for service at less than 55 mph. Typical application areas of filled tires are airports, amusement parks, farms, military, scrap yards and steel mills.

The 1000 series are two components, HCFC or HFC blown polyurethane spray isocyanurate foam systems. It is available in 1.8-3 pcf densities. This has been developed for the thermal insulation of buildings, roofs, tanks, walls, pipes and vessels. Roofing systems manufactured using 1000 series meet the requirements of ASTM E-84 (UL 790) Class A, when covered with approved coatings; Class B, combustible and non-combustible decks.
