Product Fit

This heat-activated thermoplastic adhesive film is designed for footwear manufacturers and sole converters that bond a rubber outsole or rubber sheet to an EVA midsole or EVA foam sole structure. It provides a dry-film bonding layer between the wear-resistant rubber base and the lightweight cushioning layer.

The main structure is rubber outsole or rubber sheet → hot melt adhesive film → EVA midsole or EVA foam sole. The product direction is matched to the actual rubber compound, EVA structure, sole geometry and production method.

Typical Applications and Component Uses

Sports shoe rubber outsole to EVA midsole bonding
Outdoor footwear composite sole lamination
Casual shoe rubber sole and EVA foam assembly
Rubber sheet to EVA sole-layer lamination
Molded or converted sole-component bonding

Typical Rubber-to-EVA Bonding Combinations

Bonding Structure	Typical Use
Rubber outsole → heat-activated adhesive film → EVA foam midsole	Sports and casual footwear sole assembly
Rubber sheet → thermoplastic adhesive film → EVA sole layer	Converted sole components and laminated sheet structures
SBR rubber outsole → adhesive film → EVA foam midsole	Flexible footwear sole constructions
Natural rubber outsole → adhesive film → EVA cushioning layer	Outdoor and comfort-oriented sole structures
TPR or rubber-like outsole layer → adhesive film → EVA midsole	Selected composite footwear sole designs

These are typical custom-matching project directions. Film selection is matched to the actual rubber compound, EVA construction and production workflow.

ZF-3235 Technical Reference

ZF-3235 is a modified thermoplastic polyurethane (TPU) hot melt adhesive film developed for footwear sole structures that combine rubber layers with EVA foam or EVA midsole materials. It is supplied as a liner-supported dry film and can be converted into rolls, sheets or die-cut pieces according to the sole geometry and production workflow.

ZF-3235 Reference Field	Reference Value
Material	Modified thermoplastic polyurethane (TPU)
Initial softening point	85°C
Melting range	100-140°C
Hardness	75A
Thickness	0.05-0.20 mm; custom thickness and size direction
Color	Pale yellow to translucent
Liner	PET release film
Typical heat-press reference	150-170°C; pressure above 0.6 MPa; 450-600 seconds

These are typical reference values for ZF-3235 from the supplied technical sheet. The final film direction is matched to the actual rubber compound, EVA construction, sole geometry and production workflow.

Material and Bonding Direction

Rubber-to-EVA sole bonding depends on the rubber compound, rubber surface condition, EVA foam structure, sole geometry, bonding position and whether the operation is integrated with molding or carried out as a separate lamination step. The film direction can be supplied for full-area sole bonding, shaped sheets or die-cut sole components.

Film and Grade Matching

Buyer Information	Why It Matters
Rubber type or compound	Defines the rubber-side matching direction
EVA type and foam structure	Defines the EVA-side bonding requirement
Sole shape and bonding area	Determines sheet, strip or die-cut format
Molding or lamination method	Supports the appropriate activation direction
Required flexibility and finish	Guides film-family and grade selection

Processing and Custom Supply Support

VELNORA can review the rubber compound, EVA foam structure, sole geometry, bonding position and production method to recommend a suitable film direction and supply format. The film is available as roll, slit roll, sheet or die-cut piece for footwear sole converting workflows. Clean bonding surfaces, stable equipment and even pressure support a consistent laminated structure.

Quality Control Summary

Practical quality checks cover film appearance, thickness consistency, width, roll flatness, liner release, sheet or die-cut accuracy, packaging and storage condition.

FAQ

Can this film bond a rubber outsole to an EVA midsole?

Yes. It is designed for custom-matched rubber-to-EVA sole and midsole bonding directions, including rubber outsole, rubber sheet, EVA foam and EVA sole-layer structures.

Which rubber and EVA materials can be matched?

Common directions include SBR, natural rubber and selected rubber-like outsole materials with EVA foam or EVA midsole structures. The film direction is matched to the actual rubber compound and EVA construction.

Is this product suitable for shoe insoles?

This page focuses on outsole-to-midsole bonding. Insole fabric, mesh and foam lamination belong to a different footwear application direction.

Can the film be supplied in die-cut sole shapes?

Yes. It can be supplied as roll, slit roll, sheet or die-cut material according to sole geometry and the converting workflow.
