Zeshancheng-1202 Introduction

Zeshancheng-1202 (Matrimid 5218) is a thermoplastic polyimide micro-powder that exhibits excellent solubility, along with low thermal expansion coefficient, low dielectric constant, high glass transition temperature, low density, high toughness, and low water absorption rate.

At room temperature, Zeshancheng-1202 (Matrimid 5218) micro powder is fully soluble in N,N-dimethylformamide (DMF), N,N-dimethylacetamide (DMAC), N-methylpyrrolidone (NMP), m-cresol, dimethyl sulfoxide (DMSO), γ-butyrolactone (GBL), benzyl ether (Anisole), 1,4-dioxane, carbon tetrachloride, dichloromethane, and chloroform, with a solid content of up to 40%. It is insoluble in ethylene glycol dimethyl ether, butanone, and toluene.

Zeshancheng-1202 (Matrimid 5218) micro-powder, tested by DSC, exhibits a glass transition temperature of approximately 327°C. The compression-molded profile of Zeshancheng-1202 (Matrimid 5218), tested by DMA, shows a glass transition temperature of about 346°C. Notably, its elastic modulus remains above 1.0GPa even at 320°C.

Zeshancheng-1202 (Matrimid 5218) exhibits a refractive index as low as 1.639, from which the calculated dielectric constant is approximately 2.70.

The toughness of the thermosetting resin cured with Zeshancheng-1202 (Matrimid 5218) micro-powder toughening modifier—such as special epoxy, bismaleimide, and cyanate ester resins—is 2 to 4 times higher than that of the unmodified version.

Material application:

A, serves as a high-performance thermoplastic matrix resin with high-temperature resistance and toughness

B, for toughening modification of thermosetting matrix resin

C, used for manufacturing high-temperature resistant insulating coatings and gas separation layers

D, for manufacturing components or tooling fixtures for high-temperature applications
