Colorless viscous liquid or light yellow transparent glass-like particles, odorless, tasteless, tough and plastic. Pvc Resin The relative density d420 is 1.191, the refractive index is 1.45 to 1.47, and the softening point is about 38 ° C. Ethylene-Vinyl Acetate It is not miscible with fat and water, but miscible with ethanol, acetic acid, acetone, ethyl acetate. Stable to light and heat, heating above 250 ℃ will decompose acetic acid. Boric Acid Flakes There is no acute poisoning in oral administration of 10g / kg in mice, Adl 0 ～ 20mg / kg (Shanghai).

The product is used as gum gum base material, and our country stipulates that it can be used to emulsify flavors and gum gum. The maximum usage is 60g / kg. It is used to make toy velvet and non-woven fabric. It is used as raw material for polyvinyl alcohol, vinyl acetate-vinyl chloride copolymer, and vinyl acetate-ethylene copolymer. It is also used to prepare coatings and adhesives. It is mainly used as coatings and adhesives. , Paper, chewing gum base and fabric finishing agent, it can also be used as the basic gum base of the raw material gum of polyvinyl alcohol and polyvinyl acetal; the fruit coating agent can prevent the evaporation of water and play a role in keeping fresh.
