Material Expertise

LEM’s designers and engineers have broad knowledge of the most applicable materials for various industries and uses. From the superior durability of aluminum, tried-and-true Tyvek®, and polypropylene, to polyethylene (tough and fade resistant, perfect for pole marking), UL- and RoHS-compliant materials for electrical applications, and much, much more, LEM matches ideal materials to any end use.

LEM’s material options and the key attributes/applications for each can be found below.

Signage

Aluminum – Durable, non-rusting, aluminum can be printed with enamel inks for the harshest environmental conditions. Typical thickness: .020″ – .063″

Applications – ANSI/OSHA safety signage, non-critical traffic and wayfinding signs, pole marking, substations, surveillance and security, fence and gate signs. NFPA regulatory signs

Reflective Aluminum – The same durability and non-rusting qualities as aluminum, with higher visibility at night and in poor weather conditions. Typical thickness: .063″ – .080″

Applications – traffic and MUDTC-compliant signs, pole marking

Fiberglass – For high-impact applications with abrasion-, corrosion-, and UV fade resistance that stands up to vandalism. Typical thickness: .040” – .125”

Applications – substation name signs, fence- and gate signs, phase markers, transmission tower signs, high voltage signs, and trespassing signs

Solar Grade polycarbonate – Subsurface printed material for abrasion resistance, vandal-proof durability, superior UV stability and, high impact resistance. Typical thickness: .040” – .125”

Applications – substation name signs, high voltage signs, fence- and gate signs, trespassing signs, transmission tower signs,

UV Polyethylene – High impact protection for cost-effective flexibility and non-glare, chemical resistant, UV stability. Typical thickness: .035” – .075”

Applications – construction signage, pole marking, high voltage signs, buried cable- and gas line signs, phase markers, and hydrant markers

Pressure Sensitive Vinyl – This permanent acrylic adhesive is suitable for all-purpose application to most any surface. It offers flexibility and durability for indoor/outdoor use. Typical thickness: .004”; UV-inhibiting laminates can be added for extended outdoor durability.

Applications – high voltage signs, OSHA/ANSI safety signs, security and surveillance signs, post signs

Tags

Rigid Polyvinyl chloride (PVC) – Outdoor-durable and cost-effective, LEM stocks PVC materials in multiple colors featuring writable surfaces. Typical thickness: .010” – .030”

Applications – ANSI/OSHA safety tags, lock out/tag out (LO/TO), pole marking, valve tags, chemical communications tags, production status- and quality control tags, accident prevention-, URD and underground cable tags, scaffold tags

Dead Soft Foil – Available in indoor- or outdoor-durable versions for write on with pen or pencil, this material indents to make long-lasting legends.

Applications – inspection tags, blank write-on tags

UV Polyethylene – High-impact, non-glare, and chemical-resistant, UV Polyethylene is also cost-effective, flexible and rugged. Typical thickness: .023” – .055”

Applications – pole marking, phase markers, crane- and hoist tags, parking permits, fiber optics, cable tags

Pressure Sensitive Vinyl – This is a permanent acrylic adhesive for all-purpose application to virtually any surface. It is flexible, durable, and indoor/outdoor permanent. Typical thickness: .004”, and UV-inhibiting laminates can be added for extended outdoor durability.

Applications – chemical communications tags, production status- and quality control tags

Labels

Pressure Sensitive Vinyl – This is a permanent acrylic adhesive for all-purpose application to virtually any surface. It is flexible, durable, and indoor/outdoor permanent. Typical thickness: .004”, and UV-inhibiting laminates can be added for extended outdoor durability. A stiffer/thicker film offers easier handling and increases abrasion resistance. This material is available in a wide variety of specialty adhesives for specific applications.

Applications – ANSI/OSHA regulatory labels, arc flash labels, voltage markers, hazardous material- and drum labels, numbers and letters, machine warning labels, pipe markers, lockout labels, quality control- and asset labels

Cast Vinyl – A permanent, extra-aggressive adhesive for low surface-energy applications, cast vinyl offers good dimensional stability and the lowest shrinkage of all vinyl films. It is conformable and allows application over substrates with rivets, corrugations, and/or complex curves. A UV-inhibiting over laminate can be added for superior outdoor durability in the most extreme conditions.

Applications – post-and-stake labels, equipment labels, fleet vehicles, recreational vehicles or boats, telecom labels for pedestals

Polyester – Polyester is flame-retardant, does not rip or tear, and excels in greasy or dirty environments. This scuff-resistant material survives it all: extreme humidity, tearing, abrasion, high heat, low temps, sunlight, chemical solvents, and water. It also offers mechanical stability, controlled shrinkage, and exceptional optical clarity.

Applications – electronic component labeling, equipment nameplates, UL/CSA- certified labels, computer-imprintable labels, harsh-environment labels, barcode and asset labels

Dead Soft Foil – Indoor- or outdoor-durable, dead soft foil offers excellent chemical and moisture resistance. Write on with a pen or pencil; the material indents to make long-lasting legends, and it conforms well to irregular surfaces.

Applications – inspection- and quality control labels, adhesive nameplates, property- and asset labels

Engineer-Grade Reflective – This meets ASTM D4956 Type I and is an enclosed lens, pressure-sensitive, adhesive-coated sheeting with an easy-release liner. It is outdoor-durable, resists heat, cold, water, mild acids, alkalis, and salts. Semi-conformable for flat and slightly curved surfaces

Applications – non-critical traffic signs, numbers and letters, transformer markings, pole marking

Prismatic Reflective – Meeting ASTM D4956 Type III and IV specifications, this reflects approximately 5x more light—and at a wider angle—than engineer-grade reflective material. It is typically produced as non-metalized, microprismatic lens-reflective sheeting, designed for production of reflective, durable traffic control signs, as well as work zone devices and delineators that are exposed vertically while in service. Its tougher topcoat increases durability and protects against scuffs and scratches.

Applications – permanent traffic signage, work zone devices and signage, numbers and letters, pole marking

Vinyl Cloth – Vinyl cloth is economical, strong, and highly conformable, with excellent moisture- and humidity resistance and a rubber-based adhesive that makes these labels repositionable. This material also features very good oil- and water resistance, as well as outstanding print durability.

Applications – wire and cable marking, bin markers, numbers and letters, calibration labels, circuit board- and electronic component labels
