Products Description
This strong adhesive double sided acrylic foam tape utilizes a dense, cross-linked acrylic polymer matrix that combines viscous fluid behaviors with elastic solid properties. Upon initial application pressure, the acrylic adhesive wets out microscopic surface irregularities to form immediate molecular contact, while the closed-cell foam core dissipates dynamic shear forces throughout the bond line. The synthetic acrylic composition exhibits zero degradation when exposed to continuous moisture, industrial solvents, or temperature fluctuations, making it a reliable solution for high-load structural joining where traditional mechanical fixings are unsuited.
Products Features
Viscoelastic Stress Absorption: The solid acrylic core relaxes internal mechanical strain and dampens operational vibration without bond cleavage.
High Temperature Stability: Operates continuously across thermal gradients from -40°C to 150°C without core softening or adhesive migration.
Hermetic Environmental Seal: Closed-cell foam structure forms an impermeable barrier against water, air, dust, and corrosive chemicals.
Substrate Versatility: Achieves rapid surface wet-out on high, medium, and low surface energy substrates, including anodized aluminum, glass, polycarbonates, and automotive paints.
Conversion Flexibility: Master rolls up to 960mm wide can be precision slit or custom rotary die-cut into pads, washers, and complex geometries with tight dimensional tolerances.
High Static Shear: Engineered with superior static shear resistance without creeping or detachment, making it an industrial strength double sided foam tape for demanding structural applications.

FAQ
Q1: How does the tape core prevent galvanic corrosion in metal-to-metal assemblies?
The continuous acrylic foam core acts as a non-conductive physical barrier between dissimilar metals (such as aluminum and stainless steel). By isolating the conductive surfaces, it blocks electrical currents and prevents galvanic oxidation from degrading the structural joint in humid environments.
Q2: How does the acrylic adhesive perform when exposed to industrial chemicals and automotive fluids?
The cross-linked polymer matrix provides exceptional chemical resistance against intermittent exposure to isopropyl alcohol, hydraulic fluids, motor oil, and diluted acids. Unlike rubber-based or hot-melt adhesives that swell and lose cohesion when contact occurs, the cross-linked solvent acrylic maintains its interfacial bond strength without perimeter softened migration or structural delamination.
Q3: How does the tape perform when exposed to continuous operational vibration?
The viscoelastic foam core features high internal damping capacity. Instead of transferring high-frequency resonance through the joint, the polymer matrix absorbs mechanical energy and converts it into negligible thermal energy, protecting sensitive components and preventing joint fatigue over time.
