Embossing Tactile Dome Membrane Graphic Overlay For Internet Touch Screen

Custom Graphic Printing Polycarbonate Lexan For The Thing Of Internet Touch Screen

Polycarbonate

• Polycarbonate is a type of thermoplastic polymer known for its high impact resistance and optical clarity.
• It is a popular material choice for industrial control panels, equipment covers, and overlay graphics.
• Key benefits of polycarbonate include:
  • Durability - High impact and scratch resistance
  • Transparency - Can be clear or tinted/colored
  • Machinability - Can be easily fabricated and molded
  • Thermal resistance - Withstands heat and cold well

Lexan

• Lexan is a specific brand name for a high-performance polycarbonate resin produced by SABIC.
• It is one of the most widely recognized and utilized polycarbonate materials for industrial applications.
• Lexan polycarbonate offers superior mechanical, thermal, and electrical properties compared to standard polycarbonate.
• Common Lexan products used for industrial overlays and control panels include:
  • Lexan FMR sheet - Flame-retardant grade
  • Lexan EXL sheet - Impact-modified for high durability
  • Lexan HPS sheet - High heat and chemical resistant

Lexans spec :

Material

• Common materials include vinyl, polyester, polyimide (Kapton), and polyethylene terephthalate (PET) films.
• The material needs to be durable, chemical/solvent resistant, and able to withstand temperature extremes.

Adhesive

• Pressure-sensitive adhesives like acrylic or rubber-based are common.
• The adhesive must have strong bonding strength to adhere securely to various surfaces.
• It should also resist peeling, lifting, and degradation over time.

Thickness

• Typical sticker thicknesses range from 2-10 mils (0.002" to 0.010").
• Thicker stickers are more durable but may impact conformability to uneven surfaces.

Size & Shape

• Industrial stickers come in a wide range of standard and custom sizes.
• Common shapes include rectangles, squares, circles, ovals, and die-cut custom shapes.
• Size is selected based on the specific application needs.

Here are some examples of common Lexan polycarbonate products used for industrial overlay and enclosure designs:

1. Lexan FMR (Flame Mitigating Resin) Sheets

• Formulated with flame-retardant additives to meet stringent fire safety standards
• Often used for control panel faceplates, switch plates, and equipment housings
• Available in clear, tinted, and opaque color options

2. Lexan EXL Impact-Modified Sheets

• Engineered for superior impact resistance and toughness
• Ideal for overlays, bezels, and enclosures that need to withstand abuse
• Maintains optical clarity and dimensional stability under impact

3. Lexan HPS (High Performance Sheet)

• Offers excellent chemical, temperature, and UV resistance
• Used for outdoor equipment, harsh environment enclosures
• Can be metallized or coated for specialized surface finishes

4. Lexan ML (Matte Low-Glare) Sheets

• Matte surface finish reduces glare and reflections
• Enhances readability of control panel graphics and displays
• Maintains clarity and scratch resistance of standard Lexan
