Product Overview & Custom Manufacturing Capabilitie

Yleva manufactures Recycled EVA Granules for Footwear using recycled EVA shoe material under a controlled production process to provide stable performance for molded slipper soles, sandals, midsoles, and other lightweight EVA footwear components. The material combines durability, cushioning, and processing consistency while supporting recycled material sourcing for environmentally responsible manufacturing.

The EVA copolymer contains vinyl acetate (VA), typically ranging from 5% to 40%, improving toughness, flexibility, filler compatibility, and foaming behavior compared with conventional polyethylene. Its closed-cell structure provides moisture resistance, thermal insulation, vibration absorption, and low-temperature stability suitable for footwear production.

Operating from a 16,000 m² manufacturing facility, Yleva offers custom compounding services including:

Customized Shore hardness
Customized foaming ratio
Customized recycled content
Customized colors
OEM packaging
Bulk wholesale supply
Technical support for footwear compound formulation

The material is suitable for manufacturers seeking GRS certified EVA granules, reliable batch consistency, and long-term supply from a China factory specializing in recycled EVA materials.

Material Characteristics

Closed-Cell Water Resistance

The closed-cell structure minimizes water absorption while maintaining dimensional stability after repeated exposure to moisture. This property makes the material suitable for slippers, beach footwear, and outdoor EVA products.

Stable Mechanical Performance

Compared with conventional PE materials, EVA provides improved flexibility, impact resistance, and resilience through the incorporation of vinyl acetate into the polymer chain. The material maintains consistent hardness and cushioning during footwear molding.

Easy Processing for Footwear Production

Compression molding

Injection foaming

Hot pressing

Lamination

Cutting

Adhesive bonding

Chemical Resistance

The material demonstrates resistance to:

Seawater

Mineral oil

Dilute acids

Dilute alkalis

Thermal and Acoustic Insulation

The closed-cell foam structure provides effective thermal insulation while reducing sound transmission. These characteristics make EVA suitable for products requiring lightweight cushioning and comfort.

Typical Applications

Recycled EVA granules are widely used in:

Slipper outsoles
Flip flop soles
EVA sandals
Casual footwear midsoles
EVA foam sheets
Sports footwear components
Protective padding
Hot melt adhesive compounds

FAQ

Q: Can your recycled EVA granules comply with GRS requirements and provide transaction certificates?

A: Yes. Our production system operates under GRS certification, and GRS Transaction Certificates (TC) can be provided for eligible orders within the certified supply chain. Material traceability and production records are maintained throughout manufacturing to support customer compliance requirements.

Q:How do you maintain stable hardness and foaming performance during slipper sole production?

A: We control raw material selection, formulation consistency, granulation conditions, and quality inspection throughout production. Each batch is checked for hardness and processing stability to reduce shrinkage variation and maintain consistent foaming behavior during footwear manufacturing.

Q: Can hardness, color, packaging, and foaming ratio be customized?

A: Yes. We provide customized Shore hardness, foaming ratio, recycled content, colors, packaging specifications, and OEM labeling. Sample evaluation is normally completed before mass production, with lead times depending on formulation complexity and order quantity.
