Product Description
Lightweight High Density IXPP Foam for Shoe Insole Applications
EKKOFLEX's IXPP (Irradiation Cross-Linked Polypropylene) foam is a lightweight yet high density waterproof foam material specially selected for shoe insole manufacturing. Produced through melt mixing and extrusion molding, green ion radiation cross-linking, and continuous high-temperature foaming, the material forms an independent closed-cell structure with a closed-cell rate of over 98%.
High density IXPP grades deliver firm, long-lasting arch and heel support while remaining lightweight for all-day wearing comfort. The waterproof closed cell structure keeps feet dry from moisture and sweat, while excellent resilience and shock absorption reduce foot fatigue - making IXPP foam an ideal insole material for sports shoes, casual footwear, work boots, and orthopedic insoles.
Key Features
- Lightweight & High Density - High density grades (100-200 kg/m³) provide firm support with low weight, ideal for supportive and durable shoe insoles.
- Waterproof Closed Cell Structure - Closed-cell rate over 98% with water absorption as low as ≤2%, keeping feet dry and preventing odor caused by moisture retention.
- Superior Shock Absorption & Rebound - Excellent cushioning and resilience reduce impact on heels and joints, with lasting rebound that resists flattening.
- Low Odor & Skin Friendly - Environmentally friendly and harmless with minimal VOC emissions and low odor, safe for prolonged skin contact inside footwear.
- Thermal Comfort - Low thermal conductivity provides insulation, keeping feet comfortable in both cold and warm conditions.
- Easy Processing - Can be die-cut, thermoformed, and skived into precise insole shapes, arch supports, and heel pads.
- Certified Quality - ISO 9001:2015, RoHS, and REACH certified, meeting international compliance standards.

Frequently Asked Questions
Q1: Why use high density IXPP foam for shoe insoles?
A: High density IXPP grades (100-200 kg/m³) offer firm, stable support that resists compression and flattening over time, while the closed cell structure keeps the insole lightweight and waterproof.
Q2: Is this foam waterproof enough for sweaty feet?
A: Yes. The independent closed-cell structure keeps water absorption as low as ≤2%, preventing moisture retention and the odor and bacteria growth it causes.
Q3: Will the insole lose its cushioning over time?
A: No. Thanks to irradiation cross-linking, IXPP foam has excellent resilience and compression set resistance, maintaining support and cushioning over thousands of steps, outperforming EVA insoles.
Q4: Is IXPP foam safe for direct skin contact?
A: Yes. IXPP foam is environmentally friendly and harmless with low odor and minimal VOC emissions, making it safe for prolonged contact inside footwear.
Q5: Can insoles be die-cut from this foam?
A: Yes. The foam can be die-cut, thermoformed, and skived into precise insole shapes, arch supports, heel pads, and custom orthopedic components with clean edges.
Q6: What is the MOQ, delivery time, and certification?
A: The minimum order quantity is 3000 square meters. Delivery takes 7-10 working days for stock items and 15-25 days for production orders. The product is ISO 9001:2015, RoHS, and REACH certified.
