TESA 51571, double-sided non-woven tape 160 µm, transparent, 50 m × 25 mm, for aluminium, ABS, PP, PVC and component mounting
0
Description
TESA 51571 is a double-sided non-woven tape, 160 µm thick, sized 50 m × 25 mm, transparent in colour. The very high coat-weight synthetic-rubber adhesive provides strong initial tack and fills surface irregularities, enabling reliable bonding of metals and plastics. A typical use case is fixing evaporator plates in refrigerator production.
Benefits and unique features
- High initial tack – fast, reliable mounting
- 160 µm thickness effectively compensates surface roughness
- Good adhesion to metals and many plastics: aluminium, ABS, PP, PVC, PS
- Good moisture resistance; medium UV ageing resistance
- Very good static shear at 40 °C
- Transparent appearance for discreet joints
Properties and applications
- Assembly of metal and plastic parts: durable bonding of aluminium, ABS, PP, PVC, PS.
- Refrigeration/Home appliances: mounting of evaporator plates and insulation parts.
- Irregular surfaces: thick adhesive layer levels micro-roughness.
- Humid environments: dependable hold thanks to good moisture resistance.

Storage recommendations
Store in a clean, dry place away from UV and heat, in the original packaging. Clean and degrease the substrate before application; on low-surface-energy plastics (e.g., PE/PP) run an adhesion test.
FAQ
1) Is the tape transparent?
Yes, it is transparent and provides a discreet bond line.
2) Which materials does it bond?
Metals and many plastics (e.g., aluminium, ABS, PP, PVC, PS); adhesion to steel is about 12.5 N/cm initially and 13 N/cm after 14 days.
3) What temperatures can it handle?
Around 40 °C continuous and up to 80 °C short-term.
4) Does it work on uneven surfaces?
Yes, the 160 µm thickness helps fill irregularities.
5) Will it bond PE/PP?
Yes (approx. 8–9 N/cm initial), but testing on the specific substrate is advised.
