Characteristics of Polyvinyl Alcohol Ffiber
Polyvinyl Alcohol Fiber its main features are high strength high modulus, low elongation, wear-resistant, acid and alkali resistance, weather resistance, and cement, gypsum and other substrates have a good affinity and bonding, and non-toxic, non-polluting, does not damage the human skin, harmless to the human body, is one of the new generation of high-tech green building materials. Polyvinyl alcohol, the raw material for the production of vinyl fiber, is a water-soluble high polymer with properties between plastic and rubber, and is widely used.
Polyvinyl Alcohol Fiber
Synthetic fibers made by spinning polyvinyl alcohol as raw material. This kind of fiber by formaldehyde treatment of polyvinyl alcohol formaldehyde fiber, China called Vinylon, the international said Vinylon. Comparison of low molecular weight polyvinyl alcohol as raw material by spinning the fiber is water-soluble, called water-soluble polyvinyl alcohol fiber. General polyvinyl alcohol fibers do not have the necessary heat and water resistance, the practical application of little value. Polyvinyl alcohol formaldehyde fiber has a soft, warm and other characteristics, especially the moisture absorption rate (up to 5%) in the synthetic fiber varieties is relatively high, so there is synthetic cotton called; but its heat resistance is poor, softening point of only 120 ℃.
Properties of Polyvinyl Alcohol Fiber
This product is white to slightly yellow powder or translucent particles; odorless, tasteless.
It is soluble in hot water, slightly soluble in ethanol, almost insoluble in acetone.
