PLEXUS MA440
Harmonization Code : 3904.61.00.00 | Polytetrafluoroethylene plates / sheets / film / tape / strip, self-adhesive, in rolls

Main features
- Self-Leveling Two-Part System
- 15 MPa Typical Tensile Strength
- 121 deg C Air Service Limit
Product Description
Plexus MA440 Methacrylate Adhesive uses a two-part, self-leveling methacrylate system for structural bonding of thermoplastic, metal, and composite assemblies. The uncured material has a reported density of 0.980 g/cm3. Typical cured values include 15.0 MPa tensile strength, 20% elongation, a 0.300 GPa elastic modulus, and 9.50 MPa cohesive lap-shear strength under the stated ASTM methods. A maximum air service temperature of 121 deg C is also reported. These characteristics position MA440 for structural joints where a flowable adhesive and a balance of strength and moderate elongation are needed.
Key features
- Self-leveling application: The two-part adhesive flows to wet structural joint surfaces.
- Cured mechanical balance: Typical cured properties include 15.0 MPa tensile strength and 20% elongation.
- Elevated-temperature range: The reported maximum air service temperature is 121 deg C.
Applications / Suitable for
- Structural bonding of thermoplastic, metal, and composite assemblies.
