New generation polyurethanes for sealing industry
New generation polyurethanes for sealing industry A new generation of polyurethane is expected to set new standards for the sealing industry. The polyurethane was developed for a wide array of uses and the new standard material is more resistant to water and withstands major temperature fluctuations better than existing polyurethanes. Polyurethane seals are primarily used in heavy duty machinery such as excavators and tractors. This company develops its own materials for its seals so it is not dependent on suppliers. The usage spectrum for the firm's new polyurethane ranges between -40C and 120C. This was made possible by a specific modification of the polyurethane components responsible for its temperature characteristics. It resulted in the new material's particularly favorable viscoelastic behavior. In practice, this means that seals made from the material stay flexible at low temperatures and sufficiently stable at high temperatures. In this way, development engineers take changing market requirements into account. This new generation of polyurethane seals is said to be especially well suited to construction and agricultural machinery, as well as materials handling equipment which requires high performance materials that allow far longer periods of operation. Common parts, which are universally usable and help to lower costs, are mandatory for new designs. The new polyurethane generation is a universally usable material that fulfills these requirements. This material is said to offer superb performance in heat and cold, can be used in mineral hydraulic fluids at up to 120C, and is safe from damage due to hydrolysis, even when used in water heated to 80C

Halogen-free TPEs
Low-smoke, flame-retardant thermoplastic elastomers are said to enable manufacturers of power and other flexible cords to produce non-PVC insulation and jacketing that does not contain halogenated flame retardants or phthalate plasticizers, while avoiding the processing limitations of highly filled halogen-free flame retardant (HFFR) polyolefin compounds. Inherently elastic, Halguard E 59000 series HFFR compounds contain no plasticizers, but are said to compare well with plasticized PVC in mechanical and electrical performance. They are based on polymer chemistry different from the polyolefins in other HFFR compounds, and they incorporate intumescent flame retardant formulations rather than the metal hydrate fillers used to render the polyolefin products flame retardant.

Liquid silicone developed for radiator gaskets
Elastosil RT 728 liquid silicone is offered for the production of automotive gaskets. Molded parts made from this silicone are said to be resistant to heat and coolant, and exhibit low compression set even under permanent stress. Car radiators and cooling system components can thus be reliably sealed. Elastosil RT 728 can be injection molded or mechanically dispensed straight onto the part to be sealed. Elastosil RT 728 has been chiefly developed for the production of fluid- and heat-resistant gaskets for the automotive industry. The liquid silicone is characterized by high coolant resistance. Gaskets made from Elastosil RT 728 are said to exhibit no more than 30% compression set after 1,000 hours in coolant at a temperature of 105C. After 1,000 hours at 125C, the permanent deformation is still less than 65% as soon as the stress is removed. The elastomer's high resilience delivers constant contact pressure and optimum leaktightness in the seal groove. Moreover, even long-term stress has very little effect on the overall property profile of Elastosil RT 728. Vulcanizates of the liquid silicone are said to meet delivery specifications of leading car manufacturers concerning gaskets for use in engine cooling systems. Elastosil RT 728 supports cost-efficient series production of parts by injection molding. However, the liquid silicone can also be applied by dispensing equipment straight onto the part to be sealed. Automotive subcontractors use this method to produce two-component parts. Elastosil RT 728 meets all the key requirements of this application. By virtue of its shear-thinning properties, it can be applied by dispensing equipment and is self-adhesive. Automotive suppliers use the product to make radiator components.
