Explore our flagship EVOH granule plastic raw materials engineered for superior chemical resistance across industrial and commercial applications.
A deep-dive into the chemistry, performance characteristics, and why EVOH is the material of choice for chemical resistance applications worldwide.
EVOH (Ethylene Vinyl Alcohol) is a semi-crystalline thermoplastic copolymer produced by the saponification of ethylene-vinyl acetate. Its tightly packed polymer chains create an extremely dense molecular barrier that resists the permeation of gases, solvents, oils, and a broad spectrum of aggressive chemicals — making it the gold standard in barrier raw materials.
EVOH granules exhibit outstanding resistance to hydrocarbons, aromatic solvents, chlorinated compounds, fuels, and many industrial chemicals. Its hydroxyl-rich molecular structure creates hydrogen bonds that prevent chemical molecules from penetrating the polymer matrix — a critical property in demanding industrial environments.
Available in granule form for direct extrusion, co-extrusion, blow molding, and injection molding, EVOH raw material integrates seamlessly into multi-layer film and rigid packaging structures. Its melt processability allows manufacturers to tailor barrier levels by adjusting ethylene content (typically 24–48 mol%), balancing chemical resistance with flexibility.
The EVOH resin market is experiencing robust growth driven by tightening chemical containment regulations, sustainability mandates, and the expansion of high-performance packaging sectors worldwide.
Stricter environmental regulations across the EU, North America, and Asia-Pacific are mandating improved chemical containment in fuel systems, industrial piping, and hazardous material packaging. EVOH granule raw material has become the preferred barrier layer in multi-layer structures designed to meet REACH, EPA, and GB standards for chemical permeation resistance.
EVOH enables thinner overall packaging walls while maintaining barrier performance, directly reducing plastic consumption per unit. As brands commit to recyclability and reduced carbon footprints, EVOH-based multi-layer films with compatibilized recycling streams are gaining traction as a sustainable alternative to fluoropolymer and PVDC-based barriers in chemical-resistant packaging.
The global automotive industry's shift toward low-emission vehicles has accelerated the adoption of EVOH in fuel tanks, fuel filler pipes, and fluid transport lines. EVOH's ability to reduce hydrocarbon permeation by over 99% compared to plain HDPE makes it indispensable for meeting Euro 6 and California CARB emission standards. The electric vehicle segment is also driving demand for EVOH in battery electrolyte containment components.
The global industrial chemicals market, valued at over $5 trillion, increasingly relies on EVOH-lined intermediate bulk containers (IBCs), drums, and flexible pouches for the safe storage and transport of solvents, agrochemicals, and specialty chemicals. EVOH granule raw material enables manufacturers to produce cost-effective, lightweight containers with chemical permeation resistance previously achievable only with metal or glass.
EVOH granule plastic raw material delivers targeted chemical resistance solutions across a remarkably diverse range of critical industrial and commercial sectors.
EVOH is co-extruded as a functional barrier layer in multilayer fuel tanks and fuel filler necks. Its resistance to aromatic hydrocarbons (benzene, toluene, xylene) and oxygenated fuels (ethanol blends, biodiesel) ensures compliance with global evaporative emission standards. The material maintains structural integrity across temperature ranges from -40°C to +60°C, critical for automotive fuel system reliability.
Concentrated pesticides and herbicides require packaging with superior chemical resistance to prevent permeation, leakage, and degradation. EVOH-lined multilayer bottles and pouches protect both the product integrity and the environment by effectively blocking the migration of active chemical ingredients through container walls, extending shelf life and ensuring safe handling.
In industrial piping for chemical plants and offshore platforms, EVOH barrier layers in flexible pipes prevent the permeation of aggressive media including chlorinated solvents, acids, and alkalis. This extends service life, reduces maintenance costs, and prevents soil and groundwater contamination — a key compliance requirement under ISO 15494 and ASTM D2513 standards.
Pharmaceutical manufacturers rely on EVOH's chemical inertness and exceptional oxygen barrier to protect moisture-sensitive and chemically reactive drug formulations. EVOH-based thermoform films provide a chemically resistant, FDA-compliant barrier layer that prevents interaction between the drug substance and packaging material, ensuring product efficacy throughout shelf life.
IBCs, jerry cans, and chemical drums incorporating EVOH barrier layers offer a superior alternative to steel containers for storing and transporting solvents, paints, inks, and specialty chemicals. The EVOH layer prevents hydrocarbon and solvent permeation through the outer HDPE shell, meeting UN certification requirements for hazardous material packaging and reducing product loss through evaporation.
In agricultural applications, EVOH-based multilayer films serve as fumigation barriers and soil treatment covers. The material's resistance to methyl bromide, chloropicrin, and other soil fumigants significantly reduces chemical escape into the atmosphere, improving fumigation efficacy while supporting compliance with environmental regulations restricting fumigant emissions.
From food safety to industrial chemical containment — EVOH granule raw material serves as the critical barrier layer across multiple high-value industries.
