Stellantis MS.90186 Double Layer Tape - Pressure Sensitive Adhesive

The “Stellantis MS.90186 Double-layer tape - Pressure-sensitive adhesive” standard, developed by Stellantis, a multinational automotive manufacturing company formed by the merger of Italian-American Fiat Chrysler Automobiles (FCA) and the French PSA Group, describes the requirements for closed-cell or cell-free tapes coated on both sides with a pressure-sensitive acrylic adhesive, used for bonding decorative or functional components, including but not limited to air seal strips, body side moldings, front panels, and bumpers.

These tapes can be applied to painted body surfaces, elastomeric bumpers, plastic interior surfaces, and glass. However, since adhesion will vary between these surfaces, each surface must be independently verified for adhesive performance.

The foam tapes covered in this standard are manufactured with acrylic pressure-sensitive adhesives on both sides and a backing/core consisting of acrylic, polyurethane, polyethylene foam, or film.

In the Stellantis MS.90186 standard, the validation requirements are divided into two parts:

• Initial qualification (material testing): A verification performed independently of a specific application to qualify the band for general use in Stellantis instruments.
• Component-level testing: Validation performed using representative production parts and substrate materials and geometries to verify the performance of the conveyor belt in the system design.

For the North American region, the application of tape to decorative or functional parts must be carried out in accordance with the relevant sections of the PS-4856 standard. The application of tape-backed parts to body surfaces, bumpers, or front panels must be carried out in accordance with PS-4856 and PF-8983 standards.

For the EMEA, APAC, and LATAM regions, the application of tape-backed parts to body surfaces, bumpers, front panels, or any other component must be carried out in accordance with standard 5.00750. Since these materials are nearing the end of their service life, the parts must comply with standard 71068.

In short, the Stellantis MS.90186 standard is a material specification developed for use within the Stellantis engineering standards system. Like many older Chrysler, Fiat, Peugeot, and PSA material specifications incorporated into Stellantis, the Stellantis MS.90186 standard defines the technical requirements that suppliers must meet before materials or components can be approved for manufacturing purposes.

This standard generally aims to ensure that specified automotive materials consistently meet defined performance, quality, durability, and manufacturing requirements throughout the vehicle lifecycle.

The primary objectives of the Stellantis MS.90186 standard are as follows:

• To define minimum material performance requirements.
• Ensuring consistent quality across multiple global suppliers.
• To verify compliance with Stellantis production processes.
• To increase the long-term durability of automotive components.
• To reduce warranty claims arising from material failures.
• To support global procurement by creating a common technical specification.

The areas covered by the Stellantis MS.90186 standard are as follows:

• Material composition requirements
• Physical properties
• mechanical performance
• Environmental resistance
• Chemical resistance
• Thermal aging performance
• Dimensional stability
• Appearance requirements
• Production process controls
• Inspection requirements
• Accept conditions
• Supplier documentation requirements

Depending on the application, this specification may also refer to internationally recognized standards such as ASTM, ISO, SAE, or Stellantis' internal laboratory procedures.

Materials evaluated according to the Stellantis MS.90186 standard undergo various laboratory tests depending on the product category. The main test methods described are as follows:

• Tensile strength
• Elongation
• Hardness
• Density
• heat aging
• Low temperature performance
• moisture resistance
• Chemical resistance
• Fluid compatibility
• UV weather resistance
• Wear resistance
• Color stability
• Fragrance and volatile organic compound (VOC) assessments (for interior materials)
• Size measurements

The tests to be performed will vary depending on the intended use of the material.

Suppliers seeking certification under the Stellantis MS.90186 standard are generally expected to do the following:

• Presenting representative production examples.
• Demonstrating compliance through accredited laboratory tests.
• Maintaining consistent production processes.
• To inform Stellantis of any material or process changes.
• To support Production Part Approval Process (PPAP) activities when needed.
• To ensure traceability of production batches.

These expectations are consistent with Stellantis’ broader supplier quality system and production requirements.

Meeting the requirements of the Stellantis MS.90186 standard offers several advantages:

• Improved product reliability
• Greater consistency between production locations.
• Increased vehicle durability
• Reducing production variability.
• Lower warranty costs.
• Better supplier quality performance.
• Increased customer satisfaction

The Stellantis MS.90186 standard is commonly used with the following:

• IATF 16949 Quality management system
• Automotive Industry Action Group (AIAG) Production Part Approval Process (PPAP) requirements
• Stellantis Manufacturing Requirements (MRS) for Suppliers
• Other Stellantis MS series material properties
• The referenced ASTM, ISO, and SAE test methods are applicable.

Modern vehicles rely on thousands of materials sourced from suppliers worldwide. Even small variations in material properties can affect safety, durability, appearance, and production efficiency. The MS.90186 standard helps ensure that approved materials provide consistent performance regardless of supplier or manufacturing location.

By standardizing quality criteria, this specification supports reliable production, minimizes quality variation, and contributes to the long-term performance of Stellantis vehicles.

In conclusion, the Stellantis MS.90186 standard is an internal material specification that supports consistent material quality across the company's global vehicle programs. Its role is to define the qualification, testing, quality assurance, and supplier compliance requirements for the relevant material or component. Compliance with this standard helps manufacturers produce reliable, durable, and high-quality automotive products.
