Osnabrueck, Germany -- Tubing manufacturer polyvanced says it is now offering polyurethane as a suitable alternative for high-priced and hard to get polyamide 12 in hose and tubing.
"The price of raw materials needed to produce plastic tubing is on the rise," Osnabrueck, German-based polyvanced explains. Polyamide 12 has become up to 30 percent more expensive, and is being sold on quota, the company adds. Tubing manufacturer polyvanced has responded by offering modified PU tubing to replace polyamide in many fields.
Polyvanced says the PU hoses are robust, durable and insensitive to buckling/kinking. High flexibility permits very small bending radiuses. "Mainly in the field of pneumatics, ELAST tubing of modified PU has a long and trouble-free service-life. This leads to direct cost savings for the final customer," polyvanced sales manager Matthias Strehl explained, in a 24 Feb polyvanced statement.
The polyamide supply situation may lead to supply bottlenecks, and some machine builders from the automation industry have already switched ton hoses of high performance polyurethane, said the statement. "Modified polyurethane is available at any time, and in many fields it's more economic than polyamide 12," Strehl said.
The polyvanced executive said that in addition to the properties already noted, modified polyurethane is resistant to microbial attack, and has excellent flexing endurance. "Flexibility and wear resistance characterise PU tubing," Strehl added.
Polyvanced can offer polyurethane tubing (ELAST series) to replace polyamide at short notice, although the company recognises that for automotive air-brake hose, the DIN standards specify polyamide. "Our customers are invited to contact us whenever they have any question or problem. Together we'll find a solution", Strehl said.
