Product Overview
LG Chem EA28150 EVASAN is manufactured by LG Chem’s petrochemical production base and belongs to the EVASAN series of ethylene-vinyl acetate copolymer raw materials. This grade features a vinyl acetate (VA) content of 28 wt% combined with an ultra-high melt index, delivering material characteristics of high flexibility and excellent elongation at break. The core performance advantages of this material lie in its low Shore A hardness and outstanding melt flowability, enabling uniform blending and the molding of flexible finished parts. It is highly compatible with a variety of thermoplastic processing methodologies, including extrusion coating, hot melt adhesive pelletizing, and injection molding.

Logistics and Supply Standards
The standard packaging for LG Chem EA28150 EVASAN consists of 25 kg woven bags lined with a PE inner film to seal out moisture and prevent the raw material from dampness. Permanent warehouses across global regions continuously maintain inventory to guarantee a stable supply. Executed in accordance with universal international commercial terms (Incoterms), the standard lead time for order production and delivery ranges from 7 to 14 business days, with the specific duration subject to total order volume and destination port shipping schedules. This product consists of standard plastic granules and is not classified as a hazardous chemical; it can be mixed with other compliant, non-restricted thermoplastic raw materials, supporting both sea and land LCL (Less than Container Load) shipping, which allows purchasing parties to optimize container loading efficiency.
Compliance and Quality Commitment
Customers can request a full suite of technical documents in electronic or hard-copy original formats, including the technical data sheet (TDS), material safety data sheet (MSDS), and certificate of analysis (COA) for each factory batch. LG Chem EA28150 complies with EU REACH registration regulations, the RoHS directive on the restriction of hazardous substances, and US FDA regulations related to indirect food contact. Every product batch is assigned an independent traceable lot number, fully retaining upstream raw material procurement records, production processing parameters, and finished product laboratory test data, thereby achieving full lifecycle traceability from the factory line to the customer’s production site. All shipped finished products undergo internal self-inspection alongside third-party standardized quality checks to ensure that physical and mechanical properties remain consistent with the indicators stated on the technical data sheet.
Sustainability and Environmental Statement
LG Chem EA28150 EVASAN is a thermoplastic copolymer that can enter conventional plastic recycling systems for mechanical recycling and reprocessing after being sorted and cleaned. The raw material formulation contains no added low-molecular-weight plasticizers, resulting in volatile organic compound (VOC) emissions during high-temperature melt processing that are lower than those of similar flexible polymer materials. LG Chem’s EVA production lines are equipped with energy-saving polymerization units and waste gas recovery systems, reducing carbon emissions per ton of finished product and aligning with global low-carbon manufacturing and green supply chain regulations. The base resin formulation is free of persistent bioaccumulative toxic additives, mitigating the environmental impact during the product decommissioning and disposal stages.
Frequently Asked Procurement & Technical Questions
Q1: Does EA28150 require drying before processing? What parameters should be set?
A1: This EVA grade absorbs ambient moisture during long-term storage. Prior to extrusion or hot melt pelletizing, it is recommended to dry the granules at 60 – 70 ℃ for 2 – 4 hours to eliminate surface moisture, preventing defects such as air bubbles in the finished product.
Q2: What are the sample request guidelines and the minimum oredr quantity (MOQ) standard for this grade?
A2: Laboratory test samples ranging from 1 to 5 kg can be requested, with the sample freight costs to be borne by the applicant. The minimum order quantity for conventional commercial bulk orders is one 20-foot container; when inventory is sufficient, smaller subdivided packaging orders can be negotiated.
Q3: Among EVA grades that also feature a 28% VA content, which hot melt adhesive scenarios is EA28150 suited for, and how should one differentiate during selection?
A3: EA28150 has a melt flow index of 150 g/10min, which is significantly higher than conventional low-MFI 28% VA EVA, making it ideal for low-viscosity hot melt adhesives that demand rapid flow. In contrast, grades with the same VA content but a low melt index are primarily utilized in high-cohesive-strength structural adhesive formulations; the selection between the two is based on the viscosity requirements of the adhesive compound.
