Material Profile

Thermoplastic Polyurethane

TPU is a transparent, flexible engineering polymer. In a light up lanyard it provides three properties that nylon and polyester cannot: optical clarity, waterproof sealing, and elastic recovery.

Optical clarity — the strap disappears visually, the badge carries the light

Composition
Thermoplastic polyurethane — an injection- and extrusion-grade elastomer combining rubber elasticity with plastic processability.
Clarity
Optically clear finish. Because the strap is transparent, the glowing badge appears to float at the chest without visible strap structure.
Sealing
Water and chemical resistant. The sealed electronics inside the badge operate through rain, sweat, and spills without performance loss.
Recovery
Elastic memory. The strap returns to shape after stretching or twisting, reducing deformation during long wear.
Care
Easy to clean. A wipe with a damp cloth restores the original clarity; the surface resists stains and dirt pickup.
Material Properties

Six Properties, Built In

Six material properties define the TPU light up lanyard. They come from the material itself and the sealed construction, not from any additional hardware.

PROPERTY 01
Water Resistance
The TPU compound is inherently water-resistant and the electronics are sealed inside the badge. The unit handles rain, sweat, and spills at outdoor events without performance loss.
Rain-exposed
events covered
PROPERTY 02
Flex Endurance
TPU's elastic recovery lets the strap return to shape after stretching or twisting. The connector stays secure through a full event season of daily wear.
Elastic

PROPERTY 03
UV Stability
The transparent compound is stabilized against yellowing. Multi-day outdoor events do not alter the optical clarity or the printed badge appearance.

PROPERTY 04
Temperature Tolerance
The material stays stable across the temperature range of outdoor event seasons, from cold-weather gigs to summer festivals, without effect on LED or battery performance.
All-season

PROPERTY 05
Tensile Strength
The strap and connectors withstand the pull forces of daily use. Optional breakaway buckles release under defined tension for safety compliance.

PROPERTY 06
Light Diffusion
The badge diffuses light evenly with no hot spots or dark edges. The 7 preset colors reproduce consistently across the batch.

Material Comparison

TPU vs Nylon vs Polyester

The three strap materials in the GFH series serve different procurement profiles. TPU is selected when water, clarity, and outdoor durability are the deciding factors.

Selection Note

Choose the TPU series when the event is exposed to weather, water, or humid conditions and the transparent appearance is part of the design intent. Choose nylon when full-strap lighting and crowd-wide visibility are the priority, and polyester when full-color strap printing or custom badge shapes drive the program. Because the GFH series shares one production line, mixed-material orders are supported with one quality standard and one DDP landed cost.

Deployment Scenarios

Where TPU Performs

Three scenarios where the waterproof property is the deciding factor in the procurement decision.

Rain exposed outdoor music festival with attendees wearing waterproof TPU light up lanyards

Rain-Exposed Festival

Open-air festivals where rain is expected. The sealed badge keeps lighting through the set; attendees wear the lanyard all day without performance loss.

Recommended: GFH-002, push button

Poolside activation event with attendees wearing glowing TPU lanyards near water

Poolside & Water Events

Brand activations near water, beach parties, and resort events. The transparent strap complements the environment while the badge remains fully operational.

Recommended: GFH-002, button or RF

Tropical humid climate event with attendees wearing TPU lanyards under bright sunlight

Humid & UV Climate

Tropical and coastal locations with high humidity and strong sun. The UV-stabilized compound resists yellowing; the strap stays optically clear across the event period.

Recommended: GFH-002, button

FAQ

TPU Lanyard Questions

Is the TPU lanyard fully waterproof? +
The TPU compound is inherently water-resistant and the electronics are sealed inside the badge, so the unit withstands rain, sweat, and spills at outdoor events. It is designed for rain-exposed and water-adjacent use rather than continuous underwater submersion.
Why choose TPU over nylon for an outdoor event? +
Nylon is matte and absorbs moisture; TPU is transparent, sealed, and does not absorb water. For weather-exposed events, TPU keeps both the appearance and the electronics stable, while nylon remains the better choice for printed crowds and ID programs.
Can the TPU strap be printed with a logo? +
The TPU series prioritizes optical clarity, so strap printing is minimal. Branding is carried on the ABS badge, which supports screen-printed or sublimated logos approved on a physical sample before production.
How long does the battery last in the GFH-002? +
Approximately 8 hours per set of 2 × CR2032 cells, covering a full event night. Cells are standard retail items and replaceable in the field.
Can the TPU lanyard be controlled with a remote or APP? +
GFH-002 operates by push button as standard. For synchronized control, RF remote (GFC004) can be configured on request; APP and DMX options are available on the acrylic models where the badge electronics support them.
What is the minimum order quantity? +
The standard MOQ is 200 units for custom orders. Orders above 1,000 units qualify for tier pricing. Mixed-model orders are supported on a single production line.
