EVA LG Chemical EA33045

Product Introduction EVA LG Chemical EA33045 is an EVA resin with VA content of 33% and melt index (MI) of 45 g/10min. It is well‑known for outstanding adhesiveness, high transparency, good flowability and processability, favorable compatibility and oxidation resistance. It is mainly applied in hot‑melt adhesive, coating and ink fields.

Main Applications

Hot‑melt Adhesives: Its core application field. Used to manufacture various industrial hot‑melt adhesives, packaging adhesives, wood‑working adhesives for scenarios requiring high bonding strength and stability.

Coating: As coating‑grade material, it can be used for fabric coating, functional coating and paper coating to deliver uniform coating and favorable surface finish.

Ink: Used as ink raw material to provide good adhesion and other related properties.

Foamed Products: Also applied in certain foamed shoe materials and sports goods to offer softness and elasticity.

Others: Applicable to wire & cable, toys and other fields.

Processing Technology

Processing Method	Key Parameter	Recommended Range / Description	Important Reminder
Extrusion Coating	Barrel Temperature Setting	Feeding zone:90‑120°C; Compression zone:130‑150°C; Metering zone:140‑160°C; Die:140‑160°C	Strict temperature control! Maximum processing temperature is generally not recommended to exceed 170‑180°C, otherwise thermal‑oxidative degradation will easily occur, manifested as yellowing, bubble generation and pungent odor.
	Melt Temperature	≈140‑160°C	‑
Hot‑melt Adhesive Processing	Melting Temperature	Shall be higher than its melting temperature (approx.60‑62°C), subject to formula and equipment. General operating temperature of hot‑melt adhesive reactor:150‑180°C for reference.	Avoid long‑term high‑temperature residence to prevent degradation; keep uniform stirring.
Injection Molding	Barrel Temperature	Rear zone:100‑130°C; Middle zone:130‑150°C; Front zone:140‑160°C	Low‑temperature and fast‑processing strategy is required.
	Mold Temperature	10‑40°C	Low mold temperature helps shorten cycle time.
	Injection Pressure	Medium‑low pressure	High flowability, no excessive pressure required.
