Benefits
Reliable Bonding to LSE Plastics
PX5008 is designed to provide robust adhesion to difficult-to-bond low surface energy plastics, helping simplify automotive assembly.
Primerless Application
For suitable substrates, the ZX adhesive can bond without an additional primer or adhesion promoter, potentially reducing processing steps, labor and equipment requirements.
Excellent Conformability
The acrylic foam core conforms to curved and slightly irregular surfaces, helping increase adhesive contact and improve bond performance.
Stress Relaxation
The viscoelastic acrylic foam construction helps absorb and distribute stresses caused by differences in thermal expansion and movement between bonded components.
Efficient Assembly
As a pressure-sensitive adhesive tape, PX5008 does not require a curing process like liquid adhesives, helping support efficient production assembly.
Professional Bond-Line Appearance
The dark gray acrylic foam provides a relatively discreet bond line for automotive trim and exterior components.

Why Choose 3M™ PX5008?
3M™ PX5008 is a strong choice for automotive applications that require a thin, conformable acrylic foam tape with reliable adhesion to difficult LSE substrates.
Its 0.76 mm acrylic foam construction provides a useful balance between bond-line thickness and conformability, while the ZX adhesive helps deliver strong adhesion to materials such as PP/EPDM without primer in suitable applications.
Compared with thicker PX5000 Series grades, PX5008 can be considered when the application requires a relatively thin foam tape while still benefiting from acrylic foam stress relaxation and conformability.
Installation Guide
1. Surface Preparation
Clean the bonding surfaces thoroughly to remove dust, oil, grease, release agents and other contaminants.
The cleaning method should be selected according to the actual substrate and paint system.
2. Dry the Surface
Ensure that the bonding surface is completely dry before tape application.
3. Apply the Tape
Apply PX5008 to the first substrate while avoiding contact with the adhesive surface.
Use consistent pressure to promote good contact and wet-out.
4. Remove the Liner
Remove the protective liner carefully immediately before assembly.
Avoid touching or contaminating the exposed adhesive.
5. Assemble the Components
Position the second component carefully and bring the surfaces together under controlled pressure.
Avoid excessive repositioning once the adhesive surfaces have contacted.
6. Apply Uniform Pressure
Apply sufficient, uniform pressure across the bonded area to maximize adhesive contact.
7. Allow Adhesion to Build
Although pressure-sensitive adhesive provides immediate holding power, adhesion continues to build after application.
For automotive OEM applications, validate the complete assembly process under the actual production conditions.
Storage
Store PX5008 in its original unopened packaging under recommended environmental conditions.
- Recommended storage temperature: 4°C to 38°C
- Relative humidity: 0–95% RH
- Optimum storage: approximately 23°C ± 2°C and 50% ± 4% RH
- Shelf life: 24 months from date of manufacture
- Keep the original packaging intact until use
- Protect the tape from contamination and excessive environmental exposure
- Level-wound rolls should be stored horizontally
These conditions are based on the 3M PX5008 technical documentation.
FAQ
What is 3M™ PX5008?
3M™ PX5008 is a double-sided acrylic foam tape in the PX5000 Series, primarily designed for automotive attachment applications.
What is the thickness of PX5008?
The nominal thickness is 0.76 mm (0.030 in) with a specified tolerance of ±0.08 mm.
What color is PX5008?
PX5008 uses a dark gray acrylic foam core.
Is PX5008 double-sided?
Yes. PX5008 has 3M™ ZX pressure-sensitive adhesive on both sides of the acrylic foam core.
Can PX5008 bond to PP/EPDM?
Yes. The ZX adhesive is designed for robust adhesion to LSE plastics such as PP/EPDM, including applications where primerless bonding is suitable.
Does PX5008 require primer?
Not necessarily. The PX5000 Series ZX adhesive is designed to provide adhesion to suitable LSE plastics without primer. However, the actual substrate and application must be validated before production.
What is the temperature resistance of PX5008?
3M documentation lists approximately -40°C to +90°C, with short-term exposure up to 120°C, depending on load and application conditions. Applications above 80°C require additional testing.
Is PX5008 suitable for automotive applications?
Yes. 3M identifies the PX5008 Series for automotive use, particularly for attachment applications involving LSE plastics and automotive paint systems.
Can PX5008 be die-cut?
Yes. Acrylic foam tape can be converted into custom shapes, rolls, sheets and die-cut components according to application requirements. For a specific PX5008 converting configuration, confirm the required liner and roll format.
What is the difference between PX5008 and PX5011?
The main physical difference is thickness:
- PX5008: 0.76 mm
- PX5011: 1.14 mm
Both are part of the PX5000 Series and use ZX pressure-sensitive adhesive. PX5011 provides a thicker foam layer and may be preferred when additional conformability or gap compensation is required.
