Greenlogy TEC
FRP pultruded profiles are made from glass fiber reinforcement as the raw material, resin as the binder, and glass fiber cloth as the wrapping reinforcement layer; after full impregnation, they are heated, formed and cured in a metal mold and pulled by a pulling machine to produce a new type of composite material with good physical properties, widely used in high-strength and long-span applications.

Raw material introduction — resin types
Code | Resin type | Flame retardant performance | Recommended applications |
|---|---|---|---|
VEFR-25 | Vinylester type | Oxygen index 28 and above | Acid, alkali and other harsh corrosive environments |
IFR-25 | Isophthalic type | Oxygen index 28 and above | An economical VEFR type with excellent performance, resistant to moderate acids, alkalis and solvents |
OFR-25 | Orthophthalic type | Oxygen index 28 and above | General acid and alkali environments |
Applications:
Greenlogy TEC pultruded FRP profiles are used in a wide range of applications, combining corrosion resistance, high strength, dimensional stability and light weight, with thermal and electrical non-conductivity. Durable Greenlogy TEC profiles provide years of low-maintenance service in areas traditionally specified for steel, aluminum or wood components. Today, these profiles are commonly used in highly corrosive applications that previously required stainless steel and other costly components.
