Global travel demand is up and the auto industry is booming. Growing vehicle demand has led to increased demand for parts.
As Oems become more electrified and intelligent in auto parts such as fingerprint sensors and advanced lighting features,
exterior trim will integrate more functions, but both conventional and smart trim will require a lot of tape to hold them in place.
Nowadays, auto parts manufacturers have more and more options for external adhesive solutions. It is not only a challenge to
select the right accessories to meet the installation requirements of the Oems, but also to ensure the optimal process efficiency.
How to choose PE or acrylic foam tape correctly?
PE foam tape has been used in the automotive industry for many years and has excellent cold shock resistance below -40°C due
to its superior stability. Acrylic foam tape also performs well under the requirements of cold impact resistance of oems. Both materials
can be used as tape substrates to bond plastic parts and broaden the range of applications for overall properties
Performance of PE foam tape and acrylic foam tape in four key areas:
characteristic | PE Foam Tape |
Acrylic Foam Tape |
Density | 50-400kg/m³ | 500-900kg/m³ |
Cold shock resistance |
below -40℃ Better cold shock resistance |
Below -40℃ |
Maximum stripping force at cohesive failure | 20N/cm | 60N/cm |
Tolerance compensation for thermal expansion of parts |
limited Suitable for small parts only |
yes Suitable for all kinds of external decorative parts |
How to choose the right acrylic foam tape
Make sure the tape is thick enough to compensate for thermal expansion
Thermal expansion affects different body parts and trim in different ways. Selecting acrylic foam tape of sufficient thickness is very
important for thermal expansion compensation of parts.
Effects of different temperatures on bonding of different material groups -- ABS plastics and steel, and PP and glass
Parts with length of 800mm (at room temperature) | Length difference (mm) | |
Combination of materials | expands at 90℃ | Shrinkage at -40℃ |
ABS/ steel | 3.42mm | -2.93mm |
PP/ glass | 4.34mm | -3.72mm |
