EVA Copolymer Resin (Ethylene-Vinyl Acetate)

Ethylene-vinyl acetate pellets by VA content and melt index, from foam to solar film

EVA, ethylene-vinyl acetate copolymer (HS 3901.30), is bought on two numbers: vinyl acetate content and melt index. At 18 to 22 per cent VA it is the foam resin of shoe soles, mats and sports goods; at 26 to 28 per cent with a high melt index it is the base of hot-melt adhesives; at 28 to 33 per cent VA with a melt index near 25 it is the encapsulant film resin of photovoltaic modules; and lower-VA grades go to cable compounds, agricultural film and coextruded packaging. The grades are not interchangeable, and a buyer states the VA content, the melt index, the end use and whether the lot is prime, because a foam grade in a PV film line or a film grade in a shoe press fails on sight. Producers include Hanwha Solutions, LG Chem and Lotte Chemical in Korea, Formosa Plastics in Taiwan, SABIC, Exxon Mobil, Dow, LyondellBasell, Braskem, Sipchem, Petronas Chemicals and the Chinese units at Sinopec and Levima, and they sell through distributors and their own regional offices.

China is the market that sets the price: it imports about 70,000 tonnes a month, mostly from Korea, Taiwan, Thailand and Saudi Arabia, and its PV film makers take the high-VA grades under allocation while its foam and footwear industry takes the rest. Korean exports of EVA fell through 2025 as Chinese capacity grew, and the photovoltaic grades have lost share to POE and POE-EVA films on newer cell types, so the 2026 market is easier than the shortage years. Prices are negotiated against the ICIS, Platts and ChemOrbis assessments the Asian market reads, by grade and origin. CBIL brokers EVA from producer distributors against the distributor's authorisation or the producer's allocation confirmation, the certificate of analysis for the lot and SGS or Intertek inspection at stuffing where the buyer wants it, in 25 kg bags on pallets, about 17 tonnes in a 20 ft container, on FOB, CFR and CIF terms. Send the VA content and melt index you run, the end use, the colour and the monthly volume.
