タイトルまたは説明

Polyvinyl Alcohol (PVOH, PVA) is a water-soluble white powder, an environment-friendly water soluble polymer; it provides bonding, solvent resistance, rub resistance, tensile strength and oxygen denial property.

The NeoMix PVA Powder of Chong Industrial (The Chinese Patent Owner, Patent No. ***********7,7) was produced under extra-low temperature with liquid nitrogen as refrigerant. The particle size of the power reaches **0 to **0 mesh, so the powder quickly dissolves in water under room temperature, and well mix with other powders.

Benefiting from the co-existing of hydrophilic group and hydrophobic group, PVA also has surface activity. So, it is widely used in various industries, such as adhesives, emulsion, textile, paper making, cosmetics, electronics, printing and ceramics.

Physical and chemical properties

Water-solubility:NeoMix PVA Powder dissolves quickly in water under room temperature, and the aqueous solution is transparent, non-toxic, harmless, secure and environmental.

Chemical resistance:Under room temperature, the PH value is about **7, and the viscosity is stable, hardly impact by the weak acid, alkali and organic solvent (ester, ketone, alcohols and hydrocarbon), its also oil-resistant.

Compatibility: It can be mixed with starch, synthetic resins, cellulose derivatives & surface active agent, and maintain its stability.

Applications

NeoMix PVA Powder is widely used in dry powder, powder putty, dry-mix mortar, oilfield cement, especially suitable to be used as interior & exterior wall putty and construction mortar, the main function is bonding, improving the tenacity, water-retaining property, reducing friction, enhancing working efficiency and quality (by preventing the crack & fall-off from the floated coat, and improving bonding strength and smoothing the texture).
