Our Products

TYLOSE MHS 150000 P4 25/1 (PLASTER TYPE), is a methyl hydroxyethyl cellulose (MHEC) derivative developed for the construction industry, especially for gypsum-based plasters and dry mortar systems, in fine powder form and with a high degree of etherification. With a very high viscosity value of 150.000 mPa·s, this product offers excellent water retention capacity and rapid consistency development properties in formulations, maximizing workability.

Key Application Areas

This high-performance cellulose ether has a wide range of uses in the production of construction chemicals. The main application areas are:

• Gypsum-based plasters and machine plasters
• Thin-layer plasters
• Ceramic and tile adhesives
• Autoclaved aerated concrete (AAC) block adhesives

Performance and Advantages

TYLOSE MHS 150000 P4 exhibits very high water retention when integrated into formulations. This prevents premature drying, especially in systems that rapidly absorb water like gypsum, and extends the open time. Its low impact on cement hydration and high heat stability ensure consistent performance even under challenging climatic conditions. Its rapid consistency development property saves time in production processes.

Technical Specifications

Storage and Safety

Like all finely particulate organic substances, cellulose ethers may pose a dust explosion risk. Therefore, it should be kept away from fire, sparks, and static electricity. When stored in its original packaging, in a dry place and at room temperature, the product maintains its durability for a long time. Due to its hygroscopic nature, it can absorb moisture from the air; opened packages should be tightly sealed. In high-viscosity products, a slow loss of viscosity may be observed during storage exceeding 1 year.
