What is the PEEK material used in lead nut?

1.PEEK Concept

PEEK(polyetheretherketone)is a high-performance engineering plastic with outstanding resistance to harsh chemicals,and excellent mechanical strength and dimensional stability.It offers hydrolysis resistance to steam,water,and sea water.PEEK has the ability to maintain stiffness at high temperatures and is suitable for continuous use at temperatures up to 338°F(170°C). 

2.PEEK Performance Characteristics

lStrong and stiff

lChemical resistant,hydrolysis resistant,autoclavable

lEasy to machine and fabricate

lGood mechanical properties at elevated temperatures

lUL 94 V-0 flammability rating(0.059" thickness)

lVery low smoke and toxic gas emissions when exposed to flame

3.PEEK Properties and Material Options

lVirgin PEEK(unfilled)–is naturally abrasion resistant.

lGlass-Filled PEEK–offers enhanced mechanical and thermal properties over those of basic PEEK,plus excellent resistance in harsh chemical environments and is electrically insulative.

lBearing Grade PEEK–has enhanced bearing and wear properties.TECAPEEK® PVX is an ultra high performance bearing material with wear enhancing additives.

lFDA Compliant PEEK–grades available that meet FDA requirements.

lOptical,Metal and X-ray Detectable PEEK–TECAPEEK® UD is a dark blue FDA compliant detectable PEEK designed for the food and beverage processing and pharmaceutical industries.This metal and x-ray detectable material has a heat deflection temperature of over 300°F and excellent resistance to a wide range of cleaning chemicals.

Tech Tip– When polymers are required for applications that involve large changes in temperature,best practices involve selecting a filled grade of a stable(low CTE)base polymer.When fillers are added to highly stable base polymers such as VICTREX®PEEK,the resulting composites exhibit extremely low CTE values,which makes PEEK a good candidate for applications requiring plastics with CTEs as close as possible to those of metals.
