Increasing violent crime, readily available weapons and larger glazed areas
in modern detention center designs have created a need for higher performing
security glazing materials. Sheffield Plastics has developed MAKROLON HYGARD
Laminates to meet this need. Consisting of multiple layers of polycarbonate or
polycarbonate/acrylic with bonding interlayers, these tough yet lightweight
materials offer proven resistance to physical and ballistic attack.
Sheffield offers MAKROLON HYGARD laminates in six levels of protection
ranging from containment rated sheet to UL Level 3 bullet resistant material
capable of withstanding multiple rounds fired from super powered handguns. All
MAKROLON HYGARD laminated products feature hard coated surfaces for
exceptional resistance to abrasion and UV degradation and are warranted against
coating failure, excessive yellowing and structural delamination caused by
manufacturing defects.
