U.S. natural gas futures rose about 5 percent to a near nine-week high as global energy prices surged on concerns over a pricing plan for energy exports, keeping U.S. LNG export demand near record highs. U.S. natural gas prices have risen despite forecasts of mild weather and lower-than-expected demand, which will allow utilities to fill up storage facilities next week. On Wednesday, Germany launched an emergency plan to manage gas supplies in Europe's largest economy. If natural gas supplies are interrupted or stopped, the German government could take unprecedented steps to limit electricity supply.
Affected by the increase in the price of natural gas, the price of the VAE Copolymer Latex Powder will also increase.
Description of VAE Copolymer Latex Powder
VAE copolymer latex powder products are water-soluble redispersible powders, such as ethylene/vinyl acetate copolymers, vinyl acetate/ethylene tertiary carbonate copolymers, acrylic acid copolymers, etc., with polyvinyl alcohol as a protective colloid. Because redispersible latex powders have high bonding ability and unique properties, such as: water resistance, construction and heat insulation, etc., their application range is extremely wide.
VAE copolymer latex powder has very outstanding bonding strength, improves the flexibility of the mortar and has a longer open time, imparts excellent alkali resistance to the mortar, and improves the adhesion/adhesiveness, flexural strength, water resistance, plasticity, and resistance of the mortar. In addition to abrasion performance and workability, it has stronger flexibility in the flexible anti-cracking mortar.
The role of VAE Copolymer Latex Powder in wet mortar:
Improve construction performance; improve flow performance; increase thixotropy and sag resistance; improve cohesion; extend open time; enhance water retention.
The effect of VAE Copolymer Latex Powder after the mortar is cured
Increase tensile strength; increase bending strength; reduce elastic modulus; improve deformability; increase material compactness; increase wear resistance; increase cohesive strength; reduce carbonization depth; reduce material water absorption; make materials have extreme excellent water-increasing (adding water-increasing rubber powder).

Packaging and storage of VAE Copolymer Latex Powder
It should be stored in a cool and dry place. The recommended period of use is six months. Please use it as early as possible when used in summer. If stored in a hot and humid place, it will increase the chance of agglomeration. Please use it once as much as possible after opening the bag. Finished, otherwise you need to seal the bag to avoid absorbing moisture from the air. International standard paper-plastic compound square bottom valve bag, 20-25kg/bag.
