Shanghai Shengjun Plastic Technologies Co, Ltd.

SHENGJUN PLASTIC delivers essential innovations with our deep materials science expertise as we focus on the development and production of Thermosetting Polyimide. Our Polyimide material rivals DuPont polyimide as it can withstand repeated heating up to 300 ° C while retaining its thermal and mechanical properties.

We are dedicated to solving challenges in applications that our customers, across industries and around the world, are faced with.

Also, Shengjun Plastic can provide PBI powder and PBI membrane.

Shengjun Plastic is a key developer of leading advanced materials and specialize in solving application challenges. Innovation is our business as we focus on the research and development for Thermosetting Polyimide.

Our polyimide material is a range of non- melting high-temperature polyimides which are characterized by the following properties:

No melting point, high strength over a wide temperature range from -280 ° C to +300 ° C

Excellent friction and wear properties - even without lubrication

Excellent electrical insulation properties

High compressive and creep strength

High purity, low outgassing in vacuum

High radiation resistance

Minimal thermal expansion

Long-term thermal stability up to 300 ° C, excursions to 480° C

Good chemical resistance to acids, fats and solvents

Good cryogenic properties

Inherently flame resistant
