The classic milk-white appearance provides excellent light diffusion while maintaining a clean, professional look.
Perfect for backlit signage and displays, white 7328 eliminates hot spots and creates uniform illumination across the entire surface. Impact-resistant, lightweight, and easy to fabricate using standard tools, this material can be cut, drilled, routed, and formed for professional results. UV-stabilized for outdoor use and backed by a 10-year warranty, white 7328 maintains its light-diffusing properties and appearance for years.

Frequently Asked Questions
What's the difference between white 7328, 2447, and 3015 acrylic?
White 7328 has medium light transmission (28-32%) and has been the industry standard for backlit signage for over 50 years. White 2447 has higher transmission (47-55%) for maximum LED brightness. White 3015 is nearly opaque (3% transmission) for non-illuminated applications. Choose 7328 for traditional backlit signs and balanced light diffusion.
Is white 7328 good for both LED and fluorescent backlighting?
Yes! White 7328 works excellently with both LED and traditional fluorescent lighting. It's been the signage industry standard for decades because it provides optimal light diffusion for both lighting types, creating bright, uniform illumination without hot spots. It's ideal for channel letters, light boxes, and illuminated signs.
How is white 7328 different from white 3015?
White 7328 is translucent and allows 28-32% light transmission, making it ideal for backlit signage. White 3015 is nearly opaque with only 3% light transmission, making it better for solid white surfaces and router-cut graphics that won't be backlit. Choose 7328 for illuminated signs, 3015 for non-illuminated applications.
Can white 7328 be used outdoors?
Yes, white 7328 acrylic is UV-stabilized and suitable for outdoor use. It resists yellowing and maintains its light-diffusing properties for years in outdoor conditions, backed by a 10-year limited warranty. It's commonly used for outdoor illuminated signs, channel letters, and commercial signage.
