History of pearl cellulose
Pearl cellulose is classical natural polymer of the cellulose in the form of regular spherical particles with the macrocellular structure. It is being delivered to the domestic and also foreign markets under commercial name PERLOZA.
The basic technological procedure was developed in the Institute of Macromolecular Chemistry in Prague (Ústav makromolekulární chemie Praha, thereinafter ÚMCH). In the frame of applied research of the pearl cellulose the pilot unit was developed in the former company Severočeské chemické závody Lovosice (on the present Lovochemie a.s.) in 1987. In the following years this unit was gradually equipped with new devices and intensified.
In the cooperation with ÚMCH Prague also the range of final products was expanded to the scope of the current offer.
The company PERLOZA s.r.o. commenced its operations and manufacturing of pearl cellulose on the 1st of August, 2003, when it purchased and took over the newly relocated factory from the company Lovochemie a.s.
In 2004 the company PERLOZA s.r.o. was certified by the standard ČSN EN ISO 9001.
In the frame of the research and development there was developed new sorbent with magnetic properties, and in cooperation with external research partners the research will be extended to the project of use of pearl cellulose in the restoration of historic materials.
The pearl cellulose has great future capacities not only in terms of providing the basic raw material – cellulose – from renewable natural resources, but especially due to the fact that new physical form and chemical composition of the product with high quality enable effective use of pearl cellulose for a wide range of applications in the field of sorbents, separation and chromatographic techniques and for the preparation of a wide range of functional polymers in the field of biochemistry and pharmacy.
