SIGN GRADE HIGH-PERFORMANCE POLYCARBONATE SHEET
Makrolon SN
Makrolon SN sheet is often selected as a replacement for both standard and impact-modified acrylic sheet due to its significantly greater impact strength - 30 times stronger than acrylic. And unlike impact-modified acrylic, Makrolon SN maintains its impact strength even at low temperatures. This superior toughness minimizes breakage during production, installation and in use, making Makrolon sheet a cost-effective alternative to acrylic sheet. It also means thinner gauges can be used to achieve lighter weight, higher performance signage. Makrolon SN sheet offers built-in durability for signs that can withstand all kinds of abuse and still look their best for years to come.
SAN DIEGO PLASTICS offers Makrolon SN in a full range of standard clear and white, standard and custom colors, sizes, gauges and patterns to match the requirements of even your most demanding projects.
Makrolon SP - SolarPlus sheet:
The answer when it comes to signs that must withstand intense sunlight.
While all Makrolon SN sheet is UV-stabilized for long life and color retention, signs that are subjected to extreme solar exposure may require the enhanced protection of Sheffield's Makrolon SP sheet. It offers the impact protection of Makrolon polycarbonate sheet coupled with enhanced UV protection. Using advanced extrusion technology, Sheffield Plastics has created a tough product designed to be made into the toughest signs under the sun.

Makrolon AR - Abrasion Resistant sheet:
Polycarbonate's Strength and Glass-like Hardness.
From drive-through menu covers and office park directories to mass transit signs and permanent sign boards - any place where your signs may be subjected to pedestrian contact, vandalism or graffiti - a covering of this new abrasion-resistant sheet is the right option to assure long-lasting protection. The combination of impact strength and surface durability assures resistance to both cyclical cleaning and abuse.

PHYSICAL PROPERTIES: PERFORMANCE PLUS
Makrolon polycarbonate sheet provides high impact and heat resistance, in addition to tight thickness tolerance and easy fabrication characteristics. Over the past few years, Sheffield's Makrolon sheet has been utilized in major signage programs in the field and demonstrated its performance in the most demanding sign environments.

Sheffield Plastics, Inc. together with its European affiliate, ranks as the second largest producer of polycarbonate sheet in the world. The company's emphasis on customer service, technology, quality and cost-competitiveness has made Sheffield a major polycarbonate sheet supplier in markets such as construction, electronics, aviation and transportation. New production facilities are now in place to bring these same advantages to customers in the sign industry.

THERMOFORMING
Makrolon polycarbonate sheet can be thermoformed with excellent results on standard equipment using conventional polycarbonate forming techniques. The sheet requires pre-drying to remove excess moisture. Drying guidelines are furnished in this chart.

STRIP HEATING
Strip heating is one way to achieve localized bending of Makrolon sheet for use in signs. Heating both sides at the bend area will help achieve optimum results. Drying is recommended unless the material is .118" or less in thickness.
BONDING AND CEMENTING
In solvent bonding using MDC (methylene dichloride), apply to surfaces to be bonded and hold parts under pressure until cured. Add 10% glacial acetic acid for the best joint appearance.
Urethane adhesives for polycarbonate, which provide optimum impact resistance and flexibility are available from SAN DIEGO PLASTICS, INC.
CUTTING AND SAWING
Makrolon sheet can be cut with most common hand-held and table-mounted saws, including circular saws, routers and band saws using standard blade designs for polycarbonate. For end milling and routing, high rotating speeds or low feed rates are advisable.
SHEARING, PUNCHING AND BLANKING
Unlike acrylic, which will shatter, Makrolon sheet resists cracking or crazing when shearing, punching or blanking, as long as the proper sharp tools are used.
PAINTING AND SILK SCREENING
Makrolon polycarbonate sheet can be painted by silk screening or standard spray techniques using inks and paints commonly available for polycarbonate sheet.
