Osnabrueck, Germany - Drive belts with a circular cross-section made from thermoplastic materials add flexibility and durability, pushing economic efficiency up, claims developer Polyvanced GmbH of Osnabrueck. The hose producer recently added such round belts, made from thermoplastic polyurethane and polyester elastomers, to its extensive product range, saying the weldable round cords are used mainly as drive elements as well as for transport purposes.
"The premium material properties ensure a very high durability and thus high economic efficiency of the products," explained Polyvanced sales manager Matthias Strehl, in a 3 Feb company statement..
Potential key markets are in the food industry, including the luxury end, as well as in the packaging industry, textiles, wood and ceramic processing and the chemicals industry.
"In times of economic tension the advantages of Polyvanced round belts are of special interest to our customers," claimed Strehl. Polyvanced said the belts can be quickly installed on site using mobile welding equipment, which reduces machine downtime, he added.
Belts can be easily cut to the required length, giving economical stock-keeping. The two thermoplastics have good resistance to oil, grease, water, food as well as a multitude of chemicals, said Polyvanced. Its new round belts are typically exploited in mechanical and apparatus engineering as well for driving roller conveyors, the company said.
The high flexibility of the round belts allows them to be installed and then to function "in the most confined space," said Strehl. Various colours and hardnesses (between 80 Shore A and 55 Shore D) are available in a standard outside diameter range of 3 to 20 mm. The product is delivered either on rolls or cut into segments.
Polyvanced ceo Dr Robert Mayr said in the company statement that he sees the competence and reliability of production and process handling as a key issue on the road to success. Another important issue is ongoing development of equipment and manufacturing processes. "This has the potential to improve an operation's delivery performance, quality and power to compete," the executive continued.
Hose and tubing maker Polyvanced produces some 45 million metres of hose a year for key customers in automation, construction, environmental technology, medical technical systems and the automotive industry as well as healthcare and leisure. The company currently employs some 120 people in Europe.
