Bartlett first department posted in Division 2

The Bartlett Fire Protection District serves the Village of Bartlett, as well as unincorporated areas of Hoffman Estates and parts of Wayne Township. This unique coverage spans two counties—Cook and DuPage. Bartlett is dispatched through DU-COMM but is part of MABAS Division 2. The department operates from three stations: two are staffed with ambulances and engine companies, while the third houses a jump unit equipped with a tower ladder, a 3,000-gallon tanker (tender), and a brush truck. Over the years, the department's apparatus have been painted in black over red, though they were once bright yellow. One notable example is a 1993 Seagrave engine that was originally delivered in yellow and later repainted to black and red. In recent years, Bartlett has acquired three new Pierce Velocity engines, replacing older units such as two E-ONE engines and a pair of Seagrave models. Before that, in the 1980s, the department—then known as Bartlett and Countryside FPD—purchased engines from Howe and Grumman, including a pair of Ford C8000-based units. Earlier still, in the 1970s, they operated Hendrickson/Howe and Ford/Howe engines, some of which are now preserved or displayed in local collections. Among the most historically significant pieces of equipment is a 1997 HME/US Tanker 3,000-gallon tender, one of only three in the area, shared with Palatine Rural and East Dundee FPDs. These units worked together during a major fire in Barrington in September 2008. Prior to this, Bartlett had an 8,000-gallon tractor-trailer tanker, powered by an L-Series Ford, which served the district until the newer HME model was introduced. Several photographs capture the evolution of the department’s fleet. A 1993 Seagrave TB30DF, once painted yellow, now sits in storage and is for sale. Another 1993 Seagrave, Engine 612, was part of a pair of similar units delivered in the early 1990s. In the 1980s, two Ford/Grumman engines, including Engine 618, were in service, built on Ford C8000 chassis. Earlier models, like the 1973 Hendrickson/Howe Engine 612 and the 1977 Hendrickson/Howe Engine 613, showcased different configurations, with high-side compartments on some units. Even older, a 1963 Ford C950/Howe engine, #616, was one of the first large pumpers in the department. It featured a 1,000-GPM pump and carried 800 gallons of water. These vintage vehicles are now preserved in local collections, offering a glimpse into the past of Bartlett Fire Department.

PE Sheet Rod

HONY®Polyethylene (PE) plastic is a semi-crystalline thermoplastic with high toughness and excellent chemical resistance. Compared with other plastics, polyethylene plastics have lower mechanical strength and high temperature resistance.High Density Polyethylene (HDPE) sheet is extremely strong against impact, abrasion resistant, and exhibits a low coefficient of friction. The material is also moisture, stain, and odor resistant, and is FDA approved for use in the food processing industry (mainly for cutting boards). The material's durability makes it a perfect match for a variety of applications such as water tanks, chute linings, bottle/bottle cap production and numerous other industrial uses. Borated HDPE offers radiation protection in nuclear facility applications.

High-density Poly Ethylene also is known as HDPE is made from a cord of ethylene molecules (the poly part of polyethylene), and is famous for its light weight and high durability.

The preference of HDPE sheets is increasing from leaps and bounds in the market today, as it's able to cut down on the material which is then used for producing and packaging products for its strength and weight.

It is also available at tap plastics in sheet form with either a smooth or textured surface. The textured surface is also called cutting board. Both smooth and textured surfaces are FDA approved for food contact.

HONY®PE series products include the following materials:

Polyethylene (PE) Polyethylenes are semi-crystalline materials with excellent chemical resistance, good fatigue and wear resistance and a wide range of properties. Polyethylenes are easy to distinguish from other plastics because they float in water. Polyethylenes provide good resistance to organic solvents, degreasing agents and electrolytic attack. Polyethylene is used more than any other thermoplastic polymer. There are a wide variety of grades and formulations available that have an equally wide range of properties.

POLYETHYLENE GRADES Low Density Polyethylene (LDPE) This extruded material offers good corrosion resistance and low moisture permeability. It can be used in applications where corrosion resistance is important, but stiffness, high temperature, and structural strength are not. A highly flexible product, LDPE is used widely in orthopaedic products, or where mobility without stress fatigue is desired. LDPE is also frequently used in consumer packaging, bags, bottles, and liners.

POLYETHYLENE GRADES High Density Polyethylene (HDPE) Representing the largest portion of the polyethylene applications, HDPE offers excellent impact resistance, light weight, low moisture absorption, and high tensile strength. HDPE is also non-toxic and non-staining and meets FDA and USDA certification for food processing.

Ultra High Molecular Weight Polyethylene (UHMW PE) UHMWPE is light weight (1/8 the weight of steel), high tensile strength, and is easily machined. It is the ideal material for many wear parts in machinery and equipment as well as a superb lining in material handling systems and storage containers. UHMW PE is self-lubricating, shatter resistant, long-wearing, abrasion and corrosion resistant. It meets FDA and USDA acceptance for food and pharmaceutical equipment and is a good performer in applications up to 180 °F (82 °C) or when periodically cleaned with live steam or boiling water to sterilize.
