PEEK NATURAL GRADES
JUTAIPEEK®NA is a type of Polymeric Profiles made from pure Polyetherether Ketone (PEEK), including sheets and rods, and the color is generally rice-yellow.(JUTAIPEEK®NAV is an extruded profile using British VICTREX PEEK Polymers 450G raw materials, and JUTAIPEEK®NAG is an extruded profile using domestic raw materials) Pure PEEK is a kind of polymeric materials with outstanding heat-resistance (long term service temperature=240 -260℃), outstanding resistance to chemicals (almost only concentrated H2SO4, HNO3 can destroy it), excellent flame retardancy and low smoke toxicity when combustion.
Product Features
JUTAIPEEK®NA type pure PEEK profiles:
● Outstanding stiffness and mechanical strength.
● Excellent resistance to creep and fatigue.

● Maintaining higher tensile strength and flexure strength、 above 200℃.

● Outstanding heat-resistance with long term service temperature is 240-260℃.
● Outstanding electrical insulation， low dielectric constant and dielectric loss.
● Outstanding resistance to chemicals.

● Excellent resistance to hot water and steam， which can be serviced long term in steam with temperature above 200℃.
● Excellent flame retardancy， which reach UL94 V-0 class for 1.6mm thickness sample.

● Low smoke generation.

● Outstanding resistance to nuclear radiation， which has the best radiation-resistance in Polymeric materials.

● Good sliding frictional property， which has better friction factor and wear rate than most of other kinds of polymeric polymers.

Smoke, Toxicity, Corrosion
Plastic combustion generates a series of toxic gases, such as hydrogen cyanide (HCN), sulfur gases (SO2, H2S), nitrogen gases (NO, NO2) and carbon monoxide (CO). These gases are more lethal than fire because they can render people incapable of escaping from the fire scene. Corrosive gases such as hydrogen fluoride (HF) and hydrogen chloride (HCl) can cause permanent damage to sensitive electronic devices.
The combustion products of JUTAIPEEK are mainly carbon dioxide (CO2) and carbon monoxide (CO). The amount of carbon monoxide produced is even less than 5% of the limit value specified in the Aviation Toxicity Standards (e.g. Boeing BSS 7238 and Airbus ATS-1000).

The toxicity of gases is usually measured based on the amount of gases that cause fatal damage to the human body. Table 2 is the test results of the National Bureau of Standards (NBS) Smoke Laboratory, which confirms that the only toxic gas produced considerably is carbon monoxide（CO).
