I. Core Technological Breakthroughs of Top 5 Domestic Brands (Highlight Improvement Points by Indicator Titles)

(I) Catalytic Process Breakthrough: Low-Temperature Acid-Free Catalysis with Sharply Reduced Glycidyl Ester Impurities

Breakthrough details: Jiaao Enviro, Liaoning Oxiranchem and Zhejiang Huangma have successively launched phosphotungstic heteropolyacid salt sulfuric acid-free catalytic new processes, eliminating traditional concentrated sulfuric acid catalysts. Epoxidation reaction temperature is reduced from 60–65°C to a low-temperature range of 48–53°C. Finished glycidyl ester byproducts drop from the industry standard 0.4%–0.45% to ≤0.17%, acid value is stably controlled ≤0.12mgKOH/g (national standard ≤0.5), and free fatty acid residues decrease by 62%. Himar and Shandong Longda completed technical upgrades of continuous epoxidation production lines with online closed-loop regulation of hydrogen peroxide feeding, lifting raw material utilization rate by 11.8%.

Downstream purchasing benefits:

1. In medical PVC and food packaging formulas, trace acidic impurities in ESBO will not accelerate PVC hydrogen chloride removal, enabling a 12%–18% reduction in downstream stabilizer (calcium-zinc / barium-zinc) addition and lower raw material formula costs;

2. No acidic precipitation from finished food films and bottle cap gaskets, with all batches smoothly passing EU 10/2011 and US FDA food migration testing to avoid export compliance inspection rejection risks.

(II) Physical & Chemical Indicator Breakthrough: Dual Upgrades of Ultra-High Epoxy Value and Ultra-Low Chroma Adapted to High-End Transparent Products

Breakthrough details: High-end dedicated ESBO grades of the five domestic top brands maintain stable epoxy value ≥6.35% (traditional national standard superior grade 6.0%). Huangma’s medical grade chroma APHA ≤30, and Jiaao’s food grade APHA ≤40, representing over 60% color reduction compared with legacy products (APHA 80–120). Iodine value is controlled ≤4.2gI/100g, far below the general industry limit of ≤6.0, with drastically reduced residual unsaturated double bonds.

Downstream purchasing benefits:

1. Transparent PVC infusion tubes, high-end food cling wrap and rigid transparent bottle caps eliminate the need for additional anti-yellowing additives, lifting finished product light transmittance by 3%–5% and boosting end-product yield;

2. Ultra-high epoxy value strengthens PVC thermal stabilization performance without yellowing or precipitation during 180°C extrusion molding, compatible with high-speed extrusion production lines and lifting downstream production efficiency.

(III) Migration Performance Breakthrough: Commercialized Low-Migration Modified Grades with Optimized Stability Under High-Temperature Working Conditions

Breakthrough details: Himar and Shandong Longda developed new polymer branched-chain modified ESBO products; molecular branched chains enhance entanglement capacity with PVC, reducing plasticizer migration rate from conventional 2.1% to ≤0.58% under 80°C accelerated migration testing. Custom cable-specific grades from Oxiranchem achieve finished product weight loss <0.3% after 720h long-term thermal aging at 105°C.

Downstream purchasing benefits:

1. Long-term oil exudation and blooming of end products are eliminated under high-temperature scenarios (automotive interior PVC, 105°C wires and cables, outdoor agricultural films), reducing after-sales return and replacement claims;

2. EU toy PVC exports (EN71, ASTM F963) meet dual phthalate and plasticizer migration control standards in one step, eliminating third-party re-inspection costs.

(IV) Green Process Breakthrough: Full-Chain Waste Reduction with Finished Product Biocarbon Indicators Meeting European and American Carbon Neutrality Certifications

Breakthrough details: All five top domestic brands realize closed-loop reuse of water washing wastewater, cutting single-ton ESBO wastewater discharge by 78%. Raw materials adopt non-GMO refined soybean oil with finished product biobased carbon content ≥89%; all brands obtained ISCC biobased certifications by 2026.

Downstream purchasing benefits:

1. End European and American brand customers (food and daily chemical packaging) can apply carbon neutrality labels for their products relying on ESBO biobased certificates, lifting product premium by 5%–12%;

2. Products comply with new EU REACH environmental appendix restrictions without additional environmental tariffs, facilitating purchasers’ deep cultivation of EU markets.

II. Latest Product & Process Indicator Breakthroughs of Top 5 International Overseas Brands (Highlight Improvements by Sector)

(I) Cargill – Raw Material Biomodification Breakthrough: Non-GMO Directional Hydrogenated Raw Materials with Mass-Produced Low-VOC Special ESBO

Breakthrough details: Leveraging its complete soybean refining industrial chain, directional hydrogenation pretreatment of soybean oil raw materials delivers finished ESBO with 47% lower volatile VOC than traditional products and 96.8% thermal retention rate of epoxy groups (conventional 91%–93%). UV-curable coating-specific modified ESBO is developed to replace 30% petroleum-based acrylic diluents as active diluents.

Downstream benefits: Coating and ink purchasers achieve drastically reduced formula VOC to easily comply with EU 2026 coating VOC new regulations without existing production equipment replacement.

(II) CHS – Weather Resistance Modification Breakthrough: UV-Resistant Anti-Aging Special ESBO Innovating Outdoor Product Anti-Yellowing Indicators

Breakthrough details: Molecular embedding of anti-UV functional group modification delivers PVC product yellowing index ΔE ≤1.8 after 1000h artificial xenon lamp outdoor aging, compared with ΔE ≥6.2 for ordinary ESBO under identical conditions. Special grades for outdoor tarpaulins and greenhouse agricultural films are mass-produced and launched.
