Polyimide vs polyamide

What is PI Polyimide material ?

PI is currently one of the best varieties of engineering plastics in heat resistance, some varieties can withstand long-term 290 ℃ high temperature for a short period of time to withstand a high temperature of 490 ℃, also resistant to very low temperatures, such as in the -269 ℃ liquid helium will not be brittle.

Types of PIs that HONY plastic can provide

30% Carbon Fiber (30 CF) Thermoplastic Polyimide (PI)

30% Glass Fiber (30 GF) Thermoplastic Polyimide (PI)

Unfilled Thermoplastic Polyimide (PI)

What is PAI Polyamideimide material ?

PAI is the highest performance, meltable plastic. It has outstanding resistance to high and low temperatures. Components machined from TORLON profiles have higher compressive and impact strength.

PAI and PI are two Extreme & Imidized Plastic with excellent performance, which one is better?

1.Difference in heat resistance

Sub-thermoset and thermoplastic, thermoset PI will be higher than PAI, PAI long-term recommended temperature is 260 ° C, PI is 288 ° C, but PI in more than 300 ° C can still be used, because it does not have a melting point. Thermoplasticity is comparable to both.

2, Mstrength differences

Although PAI has the highest mechanical strength in the reinforced plastics, with excellent wear resistance to damage, but here in the PI will still be slightly better, PI toughness, compressive strength, bending strength, etc. will be better than PAI, after all, the PI is known as the "problem solving skills", and that "there is no polyimide will not be microelectronics technology today".

3, There are differences in mobility

PAI, PI have super high mobility, but PAI disadvantage is not easy to mold.

Because of these two excellent special engineering plastics, so that "plastic instead of steel", "plastic instead of wood" can continue to promote the material will benefit greatly.
