CROWN EPT® (Acrylic Foam Tape) — Superior Material Structure & Environmental Adaptability for Versatile Bonding

EPT® is a product line brand of CROWN New Materials, dedicated to acrylic foam tapes. EPT® stands for Excellent Performance Tape, representing outstanding performance and reliable bonding capabilities.

Superior Material Structure for High-Performance Bonding

EPT® Acrylic Foam Tape is based on a polyacrylate viscoelastic material and features an integrated adhesive and foam-core structure. Its foam core adopts a 100% closed-cell structure, effectively dispersing stress generated during bonding while providing dynamic interfacial pressure compensation through material deformation. This enhances bonding stability and reliability on complex surfaces.

Excellent Environmental Adaptability for Demanding Applications

The polyacrylate viscoelastic material also provides EPT® with excellent weatherability, chemical resistance, and temperature adaptability. EPT® maintains stable bonding performance across a wide range of temperatures and effectively resists adhesive softening, chalking, and performance degradation under challenging conditions such as humidity, salt spray, and acidic or alkaline environments, supporting long-term reliable bonding.

Four Core Advantages for Versatile Bonding

Through its unique material structure and adhesive technology, EPT® offers:

• High Bond Strength: The viscoelastic acrylic adhesive conforms to microscopic pores and surface irregularities of substrates, creating effective mechanical interlocking. In laboratory temperature-cycling tests, bond strength remained above 90% of its initial value.
• Exceptional Stress Relief: When bonded surfaces experience vibration or dimensional changes caused by temperature fluctuations, the viscoelastic adhesive stretches and contracts like a cushioning spring, effectively relieving and dissipating stress through mechanical relaxation.
• 100% Closed-Cell Structure: The acrylic foam core features a 100% closed-cell structure, providing effective sealing and protection in applications such as underwater equipment and smart wearable devices.
• Broad Material Compatibility: EPT® is compatible with a wide range of commonly used industrial materials, including metals, glass, and plastics. Specially formulated solutions are also available for low-surface-energy substrates such as PP and PE, enabling reliable bonding.

Through the synergistic design of performance, structure, and material systems, EPT® adapts to different substrates, demanding environments, and diverse application conditions, providing customers with stable, efficient, and reliable bonding solutions.

Versatile Applications Across Industries

EPT® is widely used in automotive, new energy, consumer electronics, general industrial, consumer goods, and nail adhesive applications, supporting a variety of bonding needs including structural fixation, exterior assembly, sealing and protection, cushioning and vibration damping, and multi-material bonding.

End-to-End Technical Support from Product Selection to Application

From substrate and adhesive-system matching and product selection to structural design, application validation, and engineering development, EPT® provides professional technical support and tailored solutions based on customers' specific application requirements. This enables efficient integration from product selection and design validation to final application, helping customers quickly identify the right product and bonding solution.
