ESD Anti-Static Foam Sheets (EVA / IXPE / PU / EPE)
نظرة عامة
SANWEI ESD Anti-Static Foam series delivers reliable electrostatic protection and impact cushioning for sensitive electronic components and cleanroom applications. Available in EVA, IXPE, PU and EPE material options, these static-dissipative foams combine permanent ESD performance, shock absorption and cleanroom-compatible low-emission properties.
Each material is engineered for specific use cases: high-density EVA for heavy-duty cushioning, cleanroom-grade IXPE for low-particle environments, soft PU foam for conformal padding, and lightweight EPE for cost-effective general packaging. All foams feature built-in conductive formulation rather than surface coating, ensuring stable static dissipation throughout the product service life.
Widely used for electronic component packaging, transportation cushioning, workstation lining, cleanroom partitioning and precision device protection. With stable surface resistance, multiple material options and custom fabrication capabilities, SANWEI ESD foams provide tailored static-safe protection for electronics manufacturing and logistics.
وصف
ESD Anti-Static Foams are formulated with permanently conductive additives integrated into the foam matrix, delivering consistent electrostatic discharge control and physical protection across a full range of industrial applications. The product line covers four core material types to match different performance and cost requirements.
- ESD EVA Foam: High-density closed-cell EVA foam with excellent resilience and impact absorption. Ideal for heavy component packaging, equipment base pads and shock-absorbing liners. Available in multiple hardness grades.
- ESD IXPE Foam: Electronically crosslinked polyethylene foam with ultra-low particle emission and smooth surface. Designed for Class 100-1000 cleanrooms, semiconductor handling and high-purity packaging.
- ESD PU Foam: Soft open-cell polyurethane foam with excellent conformability and compression recovery. Suitable for precision component cradles, gap filling and delicate surface protection.
- ESD EPE Foam: Lightweight expanded polyethylene foam for cost-effective general purpose packaging and transportation cushioning.
All foams can be custom fabricated into sheets, rolls, die-cut shapes and custom profiles. The ESD property is permanent and will not degrade with washing, friction or normal wear. Surface resistance is consistently maintained within standard static dissipative ranges.

Frequently Asked Questions (FAQ)
What is the difference between ESD EVA, IXPE, PU and EPE foam? EVA is dense and durable for heavy cushioning; IXPE is low-particle for cleanrooms; PU is soft and conformable for delicate parts; EPE is lightweight and economical for general packaging.
Is the anti-static property permanent? Yes. The ESD performance comes from conductive additives integrated into the foam material itself, not a surface coating. It will not degrade with friction, washing or normal use.
Can you custom cut the foam to our size and shape? Yes. We offer custom die cutting, slitting, molding and profile fabrication to match your exact dimensions and design requirements.
Are these foams suitable for cleanrooms? Our ESD IXPE foam and selected grades are designed for Class 100-1000 cleanroom environments with ultra-low particle emission.
What is the surface resistance of ESD foam? The surface resistance falls within standard static dissipative ranges, complying with IEC61340 static control standards for ESD materials.
Can the foam be supplied with adhesive backing? Yes, ESD foam can be supplied with ESD-compatible pressure sensitive adhesive backing for easy installation.
