TPO Keder

TPO Keder for Non-PVC Technical Fabric Products

Thermoplastic polyolefin keder developed for compatible TPO fabric systems where non-PVC material alignment, weldability and a controlled rail fit are required.

Overview

TPO Keder is designed for manufacturers developing banners, covers, tents or membrane products around thermoplastic polyolefin materials. Full-bond construction can be reviewed for suitable material combinations to create a consistent wrapped profile..

TPO is a broad material family rather than one universal formulation. The selected grade, fabric coating, bonding layer and process settings must be compatible. Environmental and recyclability statements must refer to the approved complete construction and the actual end-of-life route.

Key Advantages

TPO material alignment - Supports non-PVC product development using compatible thermoplastic polyolefin materials.
Full-bond development options - Suitable core and fabric combinations can be evaluated for full-perimeter bonding.
Custom profile geometry - Diameter, flap width and construction can be reviewed against the rail and panel.
Fabrication-focused sampling - Trials can evaluate weldability, seam appearance and production handling.
Application flexibility - Potential use across banners, tents, covers and membrane products.
Qualified sustainability language - Claims can be based on the documented construction and target-market route.

Applications

TPO Keder can be considered for billboard and display banners, tents and marquees, tarpaulins, canopies, membrane structures, industrial curtains and custom non-PVC flexible products.

Material Development and Testing

Send the TPO fabric data sheet, coating or film structure and available joining equipment. Kedermaker can review profile geometry, flap construction and a trial plan.
Evaluation may include bonding appearance, seam formation, peel direction, rail fit, installation handling and any customer-defined environmental test. A successful laboratory sample does not replace validation in the complete finished product.

Quality and Manufacturing

Inspection can cover material identity, profile dimensions, flap width, bonding consistency, appearance, roll presentation and fit. Test methods and acceptance limits must be agreed for any claimed mechanical, weathering or environmental performance.

FAQ

What is TPO Keder?
TPO Keder is a keder construction developed around thermoplastic polyolefin materials for compatible non-PVC fabric systems.
Is TPO Keder 100% recyclable?
No universal claim should be made. Recyclability depends on the complete product, additives, mixed components, contamination and available collection route.
Can TPO Keder be full-bonded?
Full-bond constructions can be evaluated for suitable TPO material combinations. Final feasibility requires material and process trials.
Can it be welded to TPO-coated fabric?
Potentially, but the actual formulation, equipment and settings must be validated. Send the fabric data and a sample for review.
Is TPO Keder suitable outdoors?
Suitability depends on the approved grade, complete construction, exposure and required service performance. Use project-specific evidence rather than a general material assumption.
Can you create a custom TPO profile?
Custom geometry and flap construction can be reviewed subject to material, tooling, sampling, quantity and performance requirements.
