Supply high modulus polyimide film, BPDA-based polyimide film

High Modulus Polyimide film

High Modulus Polyimide Film is BPDA-based polyimide film with high modulus property. It has better tensile strength, modulus and heat resistance, etc. than PMDA-based equivalent, widely used in electrical, electronic industry, and application fields requiring high strength and ultra heat resistance fields, etc.

Note: BPDA/PMDA abbr.:3,3',4,4'-Biphenyltetracarboxylic dianhydride/ pyromellitic anhydride

Characters:

* Excellent heat resistance. * High dielectric performance.

* Higher mechanical strength, better wear resistance and toughness

* Excellent chemical resistance *Supplied with different types and sizes

Type: 1.HMPI01 has ultra tensile strength/modulus/heat resistance;

2.HMPI02 has easy workability / mouldabilty
