Dow pushes new vinyl chloride-vinyl acetate resin

Dow recently published information on its new "Vinyl Chloride-Vinyl Acetate Resin that can meet higher application requirements" on its Chinese website for epoxy products. Vinyl chloride-vinyl acetate resin is the only polymer that can be used as both a thermoplastic and a lightly crosslinked thermoset in a variety of applications. This transparent, tough resin has a Better adhesion and can be used directly in food applications. The advantages and combined properties of vinyl chloride-vinyl acetate resins make them suitable for a wide range of applications: in the packaging field they can be used as heat sealing coatings for aluminum foils on lids, bags, and drums, and as aluminum foil/plastic composites. Laminate adhesive for material film.

Due to the UCAR technology platform from United Carbonization of the United States, Dow continues its efforts to increase the benefits of vinyl chloride-vinyl acetate resin to customers throughout the value chain. “In a sense, vinyl chloride-vinyl acetate resin has become a forgotten technology,” said Rajesh Turakhia, a senior technical expert. “In universities, they have not been extensively studied, and many have vinyl chloride-vinyl acetate. Scientists with experience in the resin have retired, but these polymers still have great potential for improving the performance of current applications - this is exactly what we are paying attention to.

This product offers new options for packaging, paints, coatings, footwear and waterproof materials. The perfect combination of higher molecular weight and better flexibility and other performance advantages of vinyl chloride-vinyl acetate resin, including: excellent bond strength, obtained US Food and Drug Administration (FDA) certification, can be used to directly contact food, Fast-drying, flexible ink, low moisture transmission rate, acid and alkali resistance, excellent abrasion resistance. Dow experts stated that this combination of features has been favored for a variety of applications, including: flexible packaging, including cooking bags; rigid food packaging, including coil coating and can-cover printing; and heat-sealing adhesives for aluminum yogurt cup lids Mixture; film packaging; printing of plastic substrates, such as pasteurized beverage bags; paints and coatings; sports shoe adhesives.

The new water-based vinyl chloride-vinyl acetate resin provides the industry's leading candidate for low volatile organic compounds. In order to further strengthen customers' competitive advantage with vinyl chloride-vinyl acetate resin, Dow has developed a water-dispersible vinyl acetate resin AW-875 that utilizes the performance advantages of vinyl chloride-vinyl acetate resin without the need for solvents to meet volatile organic requirements. Compound (VOC) regulations require and protect workers and the environment. Aw-875 is the only commercial waterborne vinyl chloride-vinyl acetate resin to date and is currently available as a sample. Dow is actively seeking customers who wish to meet the higher performance requirements through the combined performance of vinyl chloride-vinyl acetate resins. “We will visit customers, share data, and look for opportunities for cooperation in the coming months,” says Turakhia. :"We believe that acrylic dispersions and coatings cannot meet the needs of customers in some key applications, but vinyl chloride-vinyl acetate resin can provide valuable advantages."
