Prismatic grade Reflective Sheeting

  Microprismatic reflective sheeting  
 -Prismatic grade specification
  ASTM D4956, Type VIII

Higher brightness
  T-7000 series provides the highest level of brightness. T-7000 series provides significantly higher levels of brightness       when compared to any glass beaded retoreflective sheeting including high intensity. T-7000 series is a natural fit for prismatic combination specifications grouping ASTM types VII, VIII, and IX. Prismatic combination specifications offer a performance level far above high intensity, glass beaded reflective sheeting.

Better conspicuity

T-7000 colors re truer colors as the material is not metallized like glass bead sheeting. Therefore the whites are white-not silver or gray, This yields a greeter level of daytime conspicuity and legibility.

Durability
T-7ooo provides 10-year durability. The all acrylic structure and the exceptionally strong welding structure and the process used to bond the materials produces a tough structure with outstanding weathering properties.

Application
The T-7000 series sheeting is the most application-friendly film of its type. In addition to being extremely forgiving in the lamination process, it has no-orientation requirements! This benefit saves sing shop money as  separate inventories are not needed for specific-orientation material. Government agencies may reduce liability as there is no risk of a sheeting orientation error creating a road sing not meeting the required specification! WhenT-700 sheeting is used, you can be assured the sing will meet specifications.

Encapsulated Lens Reflective Sheeting
-High Intensity Grade Specification ASTM D 4956,Type III

Most suitable for highway sings requiring high visibility and a high performance life cycle,
T-5000 high intensity grade sheeting provides the high visibility and safety drivers have come to expect from high brightness level sings. This sheeting has excellent entrance angularity, which is typical of encapsulated lens glass bead sheeting. T-5000 meets ASTM D 4956, type III specifications while exceeding its reflectivity requirements.

Brightness
T-5000 encapsulated lens glass bead sheeting provides the high brightness and durability long associated with this sheeting grade.

Durability
T-5000 provides 10-year durability.

Application
T-5000 series sheeting has a cellular construction which generates a high level of reflectivity. T-5000 series is suitable for all types of traffic signs mounted on rigid substrates. See Avery Dennison informational bulletins for detailed recommendations.
