  Polyester backing maintains form under heat exposure
  Operates across a wide temperature range -50°C to +150°C
  Tensile strength 25lb/in delivers resistance to elongation
  Thickness 0.06mm supports precise, low-profile masking
  RoHS compliance ensures restricted-substance conformity

**Applications**

• Suitable for masking during wave or reflow soldering processes
  Ideal for protecting component surfaces in electronics assembly
  Used for insulation layering in electrical harness fabrication
  Can be used for surface protection on painted metal during mechanical assembly
  Used with automated tape dispensers in production lines

What type of adhesive is used and how does it behave on delicate surfaces?

The tape uses an acrylic-based pressure-sensitive adhesive formulated to adhere firmly to smooth substrates while minimising residue on many delicate surfaces after removal.

How does the backing material perform during high-temperature processes?

The polyester film retains dimensional stability and resists softening at elevated temperatures, making it suitable for processes reaching up to +150°C.

Can this tape be applied in very cold environments?

Yes, it remains functional down to -50°C, so it can be handled and applied in cold-storage or low-temperature assembly conditions.

What physical property indicates its resistance to tensile load?

Tensile strength is specified as 25lb/in, which reflects its Ability to withstand pulling forces without significant stretching.

What Visual characteristic helps in precision work on small components?

Its transparent backing provides clear visibility of underlying details, aiding alignment and precise placement during delicate operations.
