Product Information

ItemDescription
Product NameEVA Thermoplastic Elastomer (Ethylene-Vinyl Acetate Copolymer, EVA Resin)
CAS No.24937-78-8
EINECS No.607-209-8
AppearanceWhite or slightly yellow translucent granules
Main TypesVA 5%-10% (Low VA) : Higher density, higher crystallinity, stronger rigidity. For agricultural film, packaging film, wire/cable sheathing, pipes.
VA 15%-22% (Medium VA) : Moderate flexibility and elasticity. For shoe foam, hot melt adhesives, toys, seals, cushion pads.
VA 25%-30% (Medium-High VA) : Excellent elasticity and flexibility, good low-temperature performance. For photovoltaic encapsulant film (EVA film), solar cell encapsulation, medical device packaging.
VA 30%-40% (High VA) : Excellent elasticity, high transparency, superior low-temperature flexibility. For premium hot melt adhesives, inks, coatings, specialty elastomers.
EVA Masterbatch/Modified Compounds : With functional additives for specific applications (color masterbatch carriers, flame retardant, antistatic, antibacterial, high-flow injection).
Crosslinked EVA : Chemically or radiation crosslinked for improved heat resistance, creep resistance, dimensional stability. For high-end foam, sporting goods, automotive interiors, electrical components.
EVA Hot Melt Adhesive/Pre-Coated Adhesive : Granular or rod form for bookbinding, packaging sealing, label coating, furniture edge banding, nonwoven lamination.
Key Physical & Chemical PropertiesDensity: 0.92-0.96 g/cm³ (VA content dependent); Melting Point: 70-100℃ (higher VA = lower melting point); HDT: 40-80℃ (dependent on VA and crosslinking); Brittleness Temperature: -70℃ to -40℃; Service Temperature: -60℃ to 60℃; Water Absorption: <0.1%.
Typical Performance ParametersMelt Flow Rate (MFR): 0.3-150 g/10min (grade dependent); VA Content: 5%-40% (standard); Tensile Strength: 8-25 MPa (VA dependent); Elongation at Break: 300%-900%; Shore Hardness: A30-D50 (low VA = harder, high VA = softer); Vicat Softening Point: 50-90℃; Light Transmittance: ≥90% (high VA transparent grades); Dielectric Constant: 2.5-3.0 (50Hz).
FeaturesCombines polyethylene processability with rubber-like elasticity; excellent low-temperature performance (brittleness temp -70℃); good flexibility, stress crack resistance; transparency and gloss; VA content adjustable for performance customization; good chemical and aging resistance; easy processing (injection, extrusion, blow molding, foaming, thermoforming); non-toxic, food contact compliant; good adhesion and compatibility.
Main ApplicationsFootwear: shoe soles, EVA slippers, sports shoe midsoles, foam materials (medium-high VA, foam+ crosslinking for lightweight, elasticity, cushioning).
Photovoltaic: solar cell encapsulant film (high transparency, high volume resistivity, weatherability, low shrink).
Packaging Film: stretch film, heavy-duty bags, agricultural film, food packaging (low VA for improved tear and puncture resistance).
Hot Melt Adhesives: bookbinding, label coating, packaging sealing, furniture edge banding, nonwoven lamination.
Wire & Cable: low-frequency/low-voltage insulation, flame-retardant jackets, communication cables (low VA for improved flexibility).
Toys/Daily Goods: soft toys, balls, yoga mats, car floor mats, children's play mats (medium VA injection molded, soft touch).
Others: medical packaging, automotive interior skins, seals, foam materials, blending/modification.

FAQ

Q1: Is Huafeng Chemical a manufacturer or a trader?
A: We are a professional service provider specializing in chemical foreign trade. Rather than being limited to the products of a single factory, we leverage the chemical industry cluster in Shandong Province to integrate production resources from multiple high-quality manufacturers. This allows us to offer a wide range of sourcing options—covering various product categories and origins—instead of simply pushing a single product. Furthermore, our core competitiveness lies in our professional foreign trade services (covering documentation, logistics, and regulatory compliance), ensuring a smooth and worry-free procurement process for you.


Q2: How is the security of my transaction guaranteed when working with Huafeng Chemical?
A: We strictly adhere to international trade rules (Incoterms® 2020) and accept various payment methods, such as Letters of Credit (L/C) and Telegraphic Transfers (T/T). For new clients, we support small-batch trial orders and can clearly define arbitration clauses and applicable laws within the contract. Additionally, we maintain a robust risk management system to help you mitigate common trade risks, such as exchange rate fluctuations, shipping delays, and document discrepancies.


Q3: Do you have experience serving clients in Russian-speaking regions?
A: Yes. We place great importance on the Russian-speaking market; our team includes Russian-speaking business professionals who are well-versed in the import regulations of Russia and the Eurasian Economic Union (EAEU). We understand the importance of EAC certification to clients in these regions and can assist with related compliance inquiries. We have established connections with chemical traders across various CIS countries and have gained valuable experience in specialized packaging and temperature-controlled shipping designed to withstand harsh local winter conditions.


Q4: How do you guarantee product quality?
A: We implement a strict supplier qualification and periodic audit system. A Certificate of Analysis (COA)—issued by the original manufacturer—is provided with every shipment. We also welcome pre-shipment inspections conducted by internationally recognized third-party agencies such as SGS, BV, or ITS. Should the test results fail to meet the standards specified in the contract, you have the right to reject the goods or request a replacement.
