Plastic materials will generally become stronger stiffer and more brittle at cryogenic temperatures.
Temperature resistant plastic sheet.
Want to know more.
Let s take a look at the four most popular heat resistant plastic materials.
Delrin plastic and delrin black delrin sheet bridge the gap between metals and plastic.
High temperature applications require plastic materials that can resist thermal degradation and maintain sufficient strength and stiffness at the required operating temperature.
A no attack possibly slight absorption.
It is good electrical and thermal insulator and has a self extinguishing per ul test 94.
For vex robotics teams hobby diy industrial crafts.
The working temp is 33 deg f to 160 deg f.
In stock and ready to ship.
Choose from our selection of plastic sheets including slippery uhmw polyethylene clear impact resistant polycarbonate and more.
Pvc applications are almost unlimited.
Worbla is a versatile product gaining popularity among hobbyist groups for its thermoformability.
Each material is suited to different applications due to variations in strength wear resistance corrosion resistance etc.
This non melting polyimide can withstand repeated heating up to 300 c without altering its thermal or mechanical properties making it a popular choice for jet engines industrial machinery cars trucks and other vehicles.
Good wear properties low friction acetal plastic sheet.
Some of these materials exceed 300 cst.
Some swelling and a small reduction in mechanical likely.
Negligible effect on mechanical properties.
However a number of high performance plastics including peek and dupont vespel are widely used as bearings seals and thermal insulators in cryogenic applications.
These materials include products such as vespel torlon peek teflon meldin celazole macor.
And the forming temperatures of 245 deg f.
High temperature plastics are typically classified as materials that can exceed 250 f in continuous operating temperature aka continuous service temperature.
Vespel without a doubt vespel can take the heat.
B slight attack by absorption.
Known for its naturally slippery surface ptfe surpasses most plastics when it comes to chemical resistance and performance in extreme temperatures.
High temperature applications often require plastics to have good creep resistance chemical resistance and friction and wear performance.
