253.8 x 241mm PEI Frosted Yellow Cold PEI Sheet with 3M 468MP Adhesive for Prusa i3 Mk3,Default NO5240

Feature:

PEI board is non-crystalline plastic. It is an amorphous high performance polymer that is made of amorphous PEI (polyether imide) made of engineering plastics extruded through the extruder at high temperature. PEI (Polyetherimide Polyetherimide) is an amber transparent solid that does not add any additives to have inherent flame retardancy and low smoke Degree, oxygen index of 47%, combustion grade UL94-V-0 level, the density of 1.28 to 1.42g / cm3. PEI is very strong of high temperature stability even non-enhanced PEI, still has a good toughness and strength.

So the use of PEI superior the thermal stability can be used to make high temperature heat resistant devices.

With excellent mechanical properties, electrical insulation properties, radiation resistance, high and low temperature resistance and wear resistance, and through over microwave.

PEI also has a very low shrinkage and good mechanical properties in the same direction. Add fiberglass, carbon fiber or other filler can be achieved to enhance the purpose of modification; and other engineering plastics can be composed of heat-resistant polymer alloy
