What is PTMEG used in?
The chief uses of PTMEG are in the production of spandex (polyurethane) fibers, polyurethane elastomers, and copolyester-ether elastomers.
What is ppg in polyurethane?
Polypropylene glycol (PPG) is an indispensable main raw material for the production of polyurethane(PU). Due to integrated production of the raw material propylene oxide (PO) to PPG, we can reliably provide high-quality PPG with few impurities.
What is Ptmg?
PTMG (Poly(tetramethylene ether)glycol / PTMG) is a linear polyether glycol with hydroxyl groups on both ends. As a polyol, it reacts readily with isocyanates (for example MDI, TDI), etc. to make resins with excellent properties.
Is glycol a polyol?
The term polyol is used for polyether polyols and polyester polyols. A typical example is polyethylene oxide or polyethylene glycol (PEG) and polypropylene glycol (PPG). Polyols are reacted with diisocyanates to produce polyurethanes. The term “polyol” is also attributed to other molecules containing hydroxyl groups.
Is PEG and PPG the same?
Polyethylene glycols (PEG) and polypropylene glycols (PPG) are humectants (which help retain or preserve moisture) or emulsifiers that can be found in many cosmetic products. They can usually be found by names starting with PEG- or PPG-.
Is ppg water soluble?
PPG P-1000E, as this product is also known, is a clear, viscous liquid at room temperature. It has a low pour point and, unlike the higher molecular weight PPGs, is completely soluble in water at 25 °C.
Is stevia a polyol?
Due to polyols reduced sweetness compared to table sugar, they are often blended with high-intensity sweeteners, such as stevia, monk fruit, and sucralose.
Is polyol a VOC?
The low VOC grade polyol has been proven to significantly reduce VOC emissions, particularly aldehyde, making it a sustainable alternative in the production of polyurethane foams for automotive interior applications such as seats, headliners, and steering wheels.
Who uses polypropylene glycol?
Polypropylene glycols are liquids, mostly insoluble in water, used to suppress foaming in industrial processes and for making polyurethane resins, hydraulic fluids, and various other materials.
What can polypropylene glycol be used for?
It is used to absorb extra water and maintain moisture in certain medicines, cosmetics, or food products. It is a solvent for food colors and flavors, and in the paint and plastics industries. Propylene glycol is also used to create artificial smoke or fog used in fire-fighting training and in theatrical productions.
What is Trimethylsiloxysilicate?
Trimethylsiloxysilicate is a highly cross-linked silicone resin primarily used for its film-forming attributes. It helps hold pigments in place while providing water-resistance in skin care and color cosmetic applications.
What kind of products can PTMEG be used for?
PTMEG is used for thermoplastic polyurethane (TPU) and cast urethane elastomers, and in urethane adhesives, sealants, and surface coatings. Products made from PTMEG- based urethane elastomers include automotive and aviation hoses and gaskets, forklift tires and wheels, roller skate wheels, industrial belts,…
Which is the largest application sector for PTMEG?
Spandex is the largest application sector for PTMEG, expanding at over 8.2% CAGR in terms of revenue owing to high demand for the production of flexible sports apparel and textiles. These fibers are exclusively used owing to their exceptional inherent characteristics such as high elasticity and durability along with higher flexibility than rubber.
How is polytetramethylene ether glycol ( PTMEG ) produced?
Published June 2019 Polytetramethylene ether glycol (PTMEG) is a waxy, white solid that melts to a clear, colorless, viscous liquid near room temperature. PTMEG is produced by the catalyzed polymerization of tetrahydrofuran (THF).
When does PTMEG turn into a transparent liquid?
Polytetramethylene Ether Glycol (PTMEG) is a white waxy solid. It turns into transparent liquid when the temperature is higher than room temperature. It dissolves easily in alcohols, esters, ketones, aromatic hydrocarbons and hydrocarbon chlorides. However, it does not dissolve in water or fatty hydrocarbons.
