《ACXplus adhesive tapes from Tesa meet UL 746C rating for outdoor applications》：
Tesa has announced that its ACXplus adhesive tape ranges have meet Underwriters Laboratories (UL) requirements to reach the UL 746C rating, which sees them classified as suitable for use in electrical equipment, particularly in outdoor applications, where parts may be exposed to extreme temperatures and conditions.
The UL 746C standard covers parts made of polymeric materials and involves various physical tests undertaken to assess their performance and suitability for use in electrical equipment evaluations.
To reach the standard, the Tesa ACXplus 705x, 706x and 707x ranges were put through an intensive testing programme covering three separate elements and conducted in accordance with the individual product’s recommended temperature ratings, in order to achieve the most precise results.
This included a cycle test where all the tapes were repeatedly immersed in water for 24 hours, then maintained for 96 hours at 35°C with 95 per cent relative humidity, before being exposed to a temperature of -35°C for eight hours. This cycle was repeated three times.
The tapes were then stored for 120 days at temperatures of at least 35°C above their recommended temperature rating before dynamic shear tests were conducted and the tapes were finally stored for seven days at 60°C, with 95 per cent relative humidity.

Key product features and benefits
According to Tesa, the ACXplus range is recognised for its unique viscoelastic properties, which provide excellent stress dissipation, allowing substrates with different rates of thermal expansion and contraction to be reliably joined.
The temperature, weather and chemical resistance provided by ACXplus means it can be used for long-term outdoor applications and materials can be effectively bonded without damaging or changing them.
ACXplus 707x offers the highest long-term resistance against extreme temperatures in combination with outstanding cold-shock resistance. This makes it suitable for use on a range of outdoor electrical applications such as signs or junction boxes, and especially where mechanical fastenings leave materials potentially vulnerable to corrosion.
