Hayat Kimya Site in Tatarstan, Russia. 

Hayat Kimya Alabuga TM 4 sets a new world record by using Voith’s QualiFlex CrownT sleeve on the ViscoNip application in Russia. The paper mill produces virgin fiber-based toilet paper, paper napkins and kitchen towels. 

In December 2017, a QualiFlex CrownT sleeve was installed at Hayat Kimya TM 4 maintaining stable machine production during the entire sleeve lifetime. Voith’s QualiFlex CrownT sleeve reached a world record life of 661 days and 473,810,000 nip cycles. The former world record sleeve on such an application was set in China, achieving 585 days. 

The customer was very satisfied with the result. “My congratulations to the whole Voith team for this excellent result and belt quality. My personal thanks to Voith for the support and proper service during the runtime of this belt,” says Mr. Lenar Safin, Tissue Production Chief at Hayat Kimya. 

With QualiFlex CrownT, Voith offers a superior press sleeve for tissue shoe press applications which enables stable machine operating conditions and optimum efficiency. Selected polyurethane materials ensure the highest possible abrasion resistance under challenging high temperature conditions. 

Compared to the conventional press sleeves, QualiFlex CrownT is especially designed for tissue applications. Conventional press sleeves show strong reactions to harsh conditions, and often suffer from hydrolysis, higher wear and reduced void volume. 

With Voith’s QualiFlex CrownT, open area and void volume can be de- signed exactly to the customer’s needs. The special heat-resistant material formulation makes this press sleeve the perfect choice for very demanding applications. 

Voith QualiFlex press sleeves extend the leading position for shoe press applications in the tissue sector.
