Material was developed to encapsulate complex wiring connectors to protect from environmental conditions and exhibit zero corrosive conditions over prolonged periods of time with no out gassing.

Rollers were developed for use in the cameras used for the Lunar Program. The elastomer material used for the rollers met the requirements needed to function in a zero-gravity environment with extremely low out gassing.

Inner-layer technology was developed to manufacture F-15 and F-16 fighter aircraft canopies. The inner-layer material is used to bond acrylic outer ply to polycarbonate inner ply. The requirements of the laminate material had to survive for extended periods of time and be in compliance of the fight profile of each aircraft.

Per our clients request, elastomeric material was developed and cast over steel cores to produce large rollers required for commercial application. The rollers were in direct contact with one another during operation. The elastomeric material developed resulted in an outstanding abrasion resistance and extremely low set properties.

A request for materials to develop a skateboard wheel was formulated and put into manufacturing using mixtures of components required to achieve high rebound while maintaining excellent cut tear resistance; allowing the wheels to slide when needed.

Using cast technology, printing belts capable of printing 132 characters and 2,500 lines per minute were developed and put into production. The resulting materials provided excellent print quality which demonstrated accuracy of characters on the belt during printing. Life span of the resulting belts was outstanding and in terms of cycle times, has equated to the distance to the moon and back several times over, while still maintaining excellent print quality.

Additional elastomers have been developed which demonstrated outstanding hydrolytic stability coupled with excellent resistance to microbial attack. Physical properties were excellent as was the low and high temperature with a Tg of -80C and a TMA of 208C.

Urea-extended systems were developed which were extruded to form a four-inch diameter tube with a wall thickness of 0.040 inches. Simula, Inc. extruded thousands of feet of material for the evaluation of BMW’s Inflatable Tubular Structure (ITS) side-impact program. The ITS air bag is a hidden component that is out of view and positioned from column A to column B. The purpose of the system is to give protection to the head in the event of a side-impact collision.

UET has developed a family of cast polymer systems required to replace rubber in bushing applications for both commercial and military applications on vehicles which demand outstanding performance.

Dampening systems were also developed to give a specific wave/duration when exposed to high G forces. The polymer pads of a unique design outperformed their rubber counterparts exhibiting superior cycle times while reducing cost.
