Rigid RIGID VINYL CHLORIDE, PVC belongs to the thermoplastics category and has an amorphous structure, high solidity and a high modulus of elasticity. It has excellent elec- trical properties, especially in the low voltage and frequency field. It is used with temperatures between – 10°C and + 60°C. Up to temperatures of 60°C, rigid PVC is stable against the majority of diluted or concentrated acids. Rigid PVC is physiologically inert. The possibility of using products in the food sector depends exclusively on the type of stabilisation. It is a good electrical insulator and absorbs little water; it can also be welded and glued.

BIEGLO offers high temperature resistant and flame retardant fibers. The application is similiar to meta-aramid, but PI fibers have its own advantages. The long-term service temperature is 260℃. The decomposition temperature is 560℃. The LOI is 38%, it means it is non-flameble fiber. The Dexnyl Polyimide fibers are applicable in many products, but they are used best in niche-applications with extreme standards for the material: 1- FR Protective clothing: e.g. military fligth clothing, flame resistand underwear, firefighter uniform etc. 2- High temperature filtration and industrial insulation: e.g. dedusting filtration for cement factories, steel or powder plants, air filtration for painting area operated at more than 300°C . 3- Composite material: taking advantage of insulation, flame retardance and high emperature resistance, chopped fiber can be used as reinforced material.
