We specializes in the research and manufacture of high-wear, self-lubricating technology and special engineering plastic bearings, gears and towline. The engineering plastics include PBI, PI, PAI, PEEK, PES, etc.

PBI is a higher level engineering plastic today. Its characteristics are as follows: 
1. The long-term working temperature is 310 °C, and the instantaneous withstand temperature can reach 760 °C. 
2, can maintain stable characteristics in acid and alkali environment. 
3. Products with higher strength in existing engineering plastics. 
4. Its hardness is one-half of that of glass. 
5, its ash can be controlled below 2ppm.
 
PI, Polyimide, because of its performance and synthesis characteristics, whether as a structural material or as a functional material, its large application prospects have been fully recognized, known as the problem solver, and is believed to have no microelectronics technology today without polyimide.
 
PAI (polyamide-imide) is a new class of engineering plastics containing amide groups, usually obtained by polycondensation of phenyl tricarboxylic anhydride and diisocyanate in DMF solution. The advent of PAI solves the technical problem that polyimide can not be injection molded in the past, and various high-precision products with complicated shapes can be formed by injection process, and the production efficiency is improved. Moreover, PAI has better heat resistance, tensile, bending, compressive strength, dimensional stability and wear resistance than other engineering plastics.
 
PEEK (polyetheretherketone) is a special engineering plastic with excellent performance. Compared with other special engineering plastics, PEEK has many excellent characteristics, its temperature resistance reaches 260 ° C and its mechanical properties are stable, self-lubricating, chemical corrosion resistance, flame retardant, peeling resistance, abrasion resistance, radiation resistance and high mechanical properties. But not resistant to strong nitric acid, concentrated sulfuric acid.
 
PES (polyether sulfone resin) is a transparent amber amorphous resin with heat resistance, hydrolysis resistance, creep resistance, dimensional stability, impact resistance, non-toxicity, flame retardancy, chemical resistance, etc. It is one of the few special engineering plastics used for molding, blow molding, foaming, coating, ultrasonic welding, etc.

Vespel Engineering Plastics. Polyimide parts have high performance chemical stability, mechanical toughness, natural lubrication and high temperature insulation. It can reduce the weight of parts, extend the maintenance interval or life, and reduce the overall cost by increasing the process uptime. It is an ideal design material with long-term use temperature of -196-300 °C and short-term temperature of 380 °C.
