Liaoning Dingjide Petrochemical’s 200,000 tpy POE (Polyolefin Elastomer) project was put into production in October 2025 at Changxing Island, Dalian, adopting state-of-the-art technology and delivering outstanding product performance. It helps shoe material suppliers and modifier companies develop high-performance products. In shoe materials, POE is mainly used in modified EVA foaming, widely applied in midsoles, insoles, outsoles, vamps, etc., with core advantages of light weight, high elasticity, low-temperature resistance and easy processability.

I. Core Application Scenarios (By Component)

1. Shoe Midsoles (Mainstream Application)

• EVA + POE blended foaming (dosage: 5%–20%): Improves resilience, compression set resistance and low-temperature flexibility, solving the problems of easy collapse and stiffening in winter of pure EVA.

• Used in midsoles of sports shoes, running shoes, basketball shoes and casual shoes, balancing light weight and cushioning.

• High-end models adopt supercritical foaming + POE for higher resilience and better durability.

2. Insoles

• POE-modified EVA/TPU insoles: High elasticity, light weight, flex resistance and fatigue resistance, overcoming easy collapse and rapid performance decay of traditional insoles.

• Applied in sports insoles, orthotic insoles and comfort insoles.

3. Shoe Soles (Outsoles)

• Pure POE or POE + rubber/TPR blend: Wear-resistant, non-slip, lightweight and low-temperature resistant, suitable for outsoles of casual shoes, beach shoes, slippers and children’s shoes.

• Replaces part of rubber to reduce weight while maintaining grip.

4. Vamps/Quarters/Decorative Parts

• POE films/extruded strips: Soft, flex-resistant, waterproof and weather-resistant, used for vamp reinforcement, edge binding, decorative trims and breathable windows.

• Composites with mesh fabric and leather enhance vamp toughness and service life.

5. Other Shoe Components

• Tongues, heel pads, arch support sheets: Lightweight, highly elastic and ergonomically fitting.

• Seals, anti-slip strips, injected shoe buckles: Aging-resistant and easy to mold.

II. Core Advantages of POE in Shoe Materials

• Lightweight: Low density (<0.89 g/cm³), lighter than rubber and some EVA materials.

• High elasticity & resilience: Cushioning, fatigue-resistant and not easy to collapse.

• Low-temperature resistance: Remains flexible without cracking at -20°C.

• Aging & chemical resistance: Sweat-resistant, ozone-resistant and UV-resistant.

• Easy processability: Compatible with injection molding, extrusion, foaming and lamination; good compatibility with EVA, PP, EPDM.

• Eco-friendly: Recyclable, in line with the green trend of shoe materials.

 III. Typical Formulations & Dosages

• Midsoles: EVA 60%–80% + POE 5%–20% + blowing agent/crosslinking agent.

• Insoles: EVA/TPU + POE 10%–30% to improve resilience and durability.

• Outsoles: POE 30%–70% + rubber/TPR + wear-resistant agent.

IV. Applicable Shoe Types

• Sports shoes, running shoes, basketball shoes, outdoor shoes

• Casual shoes, skateboard shoes, canvas shoes

• Beach shoes, slippers, sandals

• Children’s shoes, elderly shoes, orthotic shoes

• Winter shoes & cold-resistant shoes
