6 ACETAL 1.888.CURBELL www.curbellplastics.com

Acetal is a high strength, low friction engineering plastic that has excellent wear

properties in both wet and dry environments. Good dimensional stability and ease

of machining make acetal an outstanding choice for applications requiring complex

machining to tight tolerances.

Homopolymer acetal (Delrin) has superior room temperature strength, stiffness,

and toughness. Copolymer acetal has superior performance in continuous high heat

and hot water environments. Copolymer acetal also tends to have less porosity than

homopolymer acetal.

Acetal is available in glass-filled grades that offer enhanced strength and stiffness.

It is also available in a number of enhanced bearing and wear grades including:

Delrin AF, Delrin AF blend, and TECAFORMTM HPV 13.

NYLONNYCAST / NYLOIL / NYMETALTM / SUSTAMID / TECAMID TM

14 NYLON 1.888.CURBELL www.curbellplastics.com

Nylon is a strong, stiff engineering plastic with outstanding bearing and wear

properties. Nylon is frequently used to replace metal bearings and bushings,

often eliminating the need for external lubrication. Other benefits include a reduc-

tion in part weight, less operating noise, and decreased wear on mating parts.

Nylon is available in a variety of specialty formulations. Molybdenum disul-

phide-filled and oil-filled nylons have enhanced wear properties, while heat

stabilized nylon will withstand higher operating temperatures. For enhanced

strength and stiffness, nylon is also available in glass-filled grades.

In power transmission applications NYMETALTM billets made with nylon and a

metal core combine the performance advantages of nylon and metal into one

cohesive unit. The billets can be manufactured into many different components

including gears, rollers, sprockets, and augers.

of thermal expansion making it an excellent choice for applications that require

machining to tight tolerances.

PAI is available in a variety of formulations including electrical, bearing and wear,

and glass-filled grades. Electrical grade PAI has extremely high dielectric strength

and it is often used for applications where it functions as an electrical

insulator. Bearing grade PAI can be used for demanding bearing applications that

require extreme loads, speeds, and/or elevated temperatures. Glass-filled PAI has

enhanced strength and stiffness.

POLYIMIDE SHAPES

54 VESPEL POLYIMIDE SHAPES 1.888.CURBELL www.curbellplastics.com

DupontTM Vespel Polyimide is an extremely high temperature, creep resistant

material that is often used in high heat environments where thermoplastic materials

lose their mechanical properties.

Vespel is available in a variety of formulations including unfilled grades and

several low friction and wear grades. Unfilled Vespel has outstanding sealing

properties when it interfaces with metal mating parts. These properties make

Vespel ideal for use in high temperature and high pressure or high vacuum valve

seat and gasket applications.

Bearing grade Vespel will operate successfully without lubrication in many high

load, high speed, and/or high temperature environments where thermoplastic

bearings and many metal bearing materials may quickly fail.

The new SCP family of DuPontTM Vespel Polyimide Shapes exhibits enhanced

mechanical properties and superior thermal stability.
