The product designations for the Tylose® product range are based on a simple nomenclature system. Each product designation consists of three major categories which characterize the product:
Details of the classification and designation are shown in the following nomenclature system, using Tylose MHS 30007 P6 as an example. From the designation of Tylose MHS 30007 P6 it can be derived, that this grade is a methylhydroxyethyl cellulose (MH) with a high level of etherification (S) and a viscosity of 30000 mPa•s (based on Hoeppler). A modification with additives is indicated by the fact, that at least one of the last two digits of the viscosity rating is a number >0. Tylose MHS 30007 P6 is therefore a modified type. However, the last two figures of the viscosity level do not determine the level of modification and the amount of the modifying agent. „P6” signifies an ultra fine powder with a particle size < 100 µm
One of SE Tylose specialties are allyl modified HEC types, whereby the allyl modification is shown by the notation „A“ in the product name (example: Tylose HA 40 YP2).
The SE Tylose product range comprises Tylose types without delayed solubility (in general products without special notation) as well as readily soluble types with a low level of delayed solubility (notation “K”) and furthermore with delayed solubility (notation “Y”). Several Tylose H types, where it should be emphasized to be non delayed are denoted with "N" in the nomenclature (example: Tylose H 10000 NG4).
Comment on viscosity level and specified viscosity range:
Historically, the classification of the viscosity levels underlying this nomenclature is based on viscosity measurements with the Hoeppler falling ball viscometer according to DIN 53015 (2001).
However, the viscosity ranges given in the SE Tylose product specifications, are determined using Brookfield rotation viscometer.
