Acrylic vs. Glass Cover Panels: What Touchscreen Engineers Need to Know

The Great Material Debate in Touchscreen Design

For touchscreen engineers specifying cover materials, the choice between acrylic and glass cover panels represents one of the most critical design decisions. While acrylic (PMMA) was once widely used in industrial and cost-sensitive applications, modern touch technologies increasingly demand the superior performance of glass cover panels.

At [Your Company Name], we’ve manufactured both materials for 15+ years, and our experience confirms why 78% of professional touch applications now specify glass. Here’s what your engineering team should consider when selecting cover panel materials.

Technical Comparison: Glass Cover Panels vs. Acrylic

Optical Performance

Glass cover panels provide:

• 92-95% light transmission (vs. acrylic’s 88-91%)

• Consistent refractive index (1.52) across temperatures

• Minimal yellowing after UV exposure

Acrylic suffers from:

• Visible light distortion at thicknesses >3mm

• Gradual haze development in sunlight

Mechanical Durability

Our chemically strengthened glass cover panels achieve:

• 7-8H pencil hardness (vs. acrylic’s 3-4H)

• 10x better scratch resistance in Taber tests

• Withstands 100,000+ touch cycles without wear patterns

Environmental Stability

Glass maintains performance in:

• -40°C to 120°C operating ranges

• 95% RH humidity chambers

• Chemical exposure (alcohols, cleaners, oils)

Acrylic becomes brittle below -20°C and softens above 80°C.

Cost Considerations Over Product Lifetime

While acrylic has lower upfront costs (typically 30-50% less than glass), our clients find glass cover panels deliver better TCO through:

Application-Specific Recommendations

When Glass Cover Panels Are Essential:

• Public kiosks (vandal resistance)

• Medical devices (chemical sterilization)

• Automotive displays (temperature cycling)

• Military equipment (EMI protection)

Where Acrylic May Suffice:

• Short-life consumer toys

• Indoor-only prototypes

• Ultra-low-budget projects
