STK Tape supplies authentic 3M Double Coated Polyethylene Foam Tape 4625, 3M VHB Tape 4913, and 3M VHB Tape 4914, forming a comprehensive portfolio specifically engineered for Electronics & Low VOC Foam applications. Designed for cleanroom compatibility, optical clarity protection, and ultra-slim profile hardware, this tape series replaces liquid glues and mechanical fasteners across modern consumer electronics, automotive cockpits, and sensitive optical instrumentation.
3M Double Coated PE Foam Tape 4625 Profile (0.8 mm Low VOC PE Foam)
3M 4625 is a 0.8 mm (0.031 in) white closed-cell polyethylene (PE) foam tape coated on both sides with an aggressive pressure-sensitive adhesive. Formulated for low VOC emissions and high quick-stick adhesion, 3M 4625 fills micro-gaps, provides acoustic dampening, and buffers mechanical shock on plastic housings, battery enclosures, and internal electronic hardware.
3M VHB Tape 4913 Profile (0.15 mm Ultra-Thin White VHB)
Belonging to the 3M VHB Thin Foam Series, 3M 4913 is an ultra-thin 0.15 mm (6 mil) white firm acrylic foam tape featuring 3M 100MP high-performance acrylic adhesive on both sides. Engineered for zero-clearance electronic design, 3M 4913 combines ultra-low outgassing with permanent structural shear strength for display glass bonding and optical lens fixation.
3M VHB Tape 4914 Profile (0.25 mm Ultra-Thin White VHB)
3M 4914 is a 0.25 mm (10 mil) white firm acrylic foam tape utilizing the same 100MP adhesive matrix as 3M 4913. Designed for slim electronic assemblies requiring higher gap-filling tolerance and drop-test impact absorption, 3M 4914 provides high dynamic shear holding power and environmental sealing against humidity and dust.

Performance Features
Low VOC & Ultra-Low Outgassing Formulation: Protects sensitive camera lenses, optical sensors, and OLED/LCD display layers from chemical fogging and volatile organic compound contamination.
Ultra-Thin Profile for Precision Hardware: Thicknesses starting at 0.15 mm (4913) and 0.25 mm (4914) allow device designers to achieve sleek, seamless bezel-less enclosures without sacrificed bond strength.
Viscoelastic Impact Absorption: Acrylic foam cores absorb dynamic drop shocks, mechanical stress, and thermal expansion differentials across glass, metal, and plastic interfaces.
Hermetic Dust & Moisture Barrier: Closed-cell foam architecture creates a continuous environmental barrier against humidity, dust intrusion, and outdoor weathering.
