Self-repairing effects of liana as a biological model for sealing foams

For lianas, wound healing is a matter of course. Will this soon also apply for polyurethane foams from Rampf Giessharze? The research team of Dr. Olga Speck from the competence network Biomimetics of the University of Freiburg has already succeeded in achieving this on a laboratory scale. At the specialist symposium “Innovative Sealing Technologies” at Rampf in Grafenberg on 25 March 2010, the scientist will introduce the first technical application: a self-repairing membrane for pneumatic structures.

PU rigid foam insulated building blocks

Because of rising energy costs, the building materials industry is focusing increasingly on heat conductivity - the lower this value, the better the insulation will be. In a solid construction, a typical insulated external wall consists of either a double wall structure with a core insulation, or a single wall with additional external insulation. Both of these alternatives are costly and have a relatively long construction period.

Continuous production of PU foam-insulated pipes in one system

KraussMaffei Berstorff is now offering complete systems for continuous production of PU-insulated pipes. The extruded plastic pipe is given an insulating polyurethane layer, followed immediately by the addition of a protective polyethylene sheath.

Technology

Cost effective metering and dispensing

ESCO (Edge-Sweets Company) announced the development of its new ECD Basic Series metering and dispensing machines. The new range of machines fills a niche for a large customer base that seeks a simple, dynamic means of metering and dispensing.

Technology

Linseed oil-based urethane polymer for woodcare applications

Alberdingk Boley has launched the new, urethane-modified oil polymer grade Alberdingk OP 100. Application fields are impregnations or woodcare oils. The new product is a polymer dissolved in linseed oil which is suitable for all wood species.

Technology

Emission-free polyurethane dispersions

Bayer MaterialScience has launched new cosolvent-free PU dispersions for waterborne environmentally friendly two-component PU coatings. The coating films made using Bayhydrol U dispersions display properties, ranging from hard through to flexible and a velvety soft feel.

Technology

Multirange synthesis for producing polyol

H&S Anlagentechnik has developed a new reactor type (MP = multi-material to polyol) for medium sized amounts.

Technology

PU formula for large, high-strength, lightweight products

Among many other products, KraussMaffei’s customer Camoplast Inc. makes plastic hulls and decks for personal watercraft (PWC), more commonly known as jet skis. A leading PWC producer tasked its supplier Camoplast with developing a lighter hull capable of boosting PWC speed and performance, as well as saving manufacturing costs. The challenge was to achieve the weight reduction without loss of strength. Camoplast found the solution by combining KraussMaffei’s LFI process with a new formula for Baydur 814, a polyurethane system from Bayer MaterialScience (BMS). The PWC hull measuring 360 x 90 cm is the first application of this special technology.
