Hepla® PC possesses excellent impact strength, excellent mechanical strength, energy radiation resistance, electrical insulation, dimensional stability, high transparency, physiological inertia, creep resistance, and good rigidity despite of high or low temperatures. What’s more, it also can be used as food-contacted material. Although it is stable to water, mineral and organic acids, it is partially soluble in aromatic hydrocarbons, soluble in the chlorinated ones, and decomposes in strongly alkaline substances.

Reinforcement with 40% glass reduces the thermal expansion to 1.0 in/in/degrees F x 10E-5 (1.8 cm/cm/degrees C x 10E-5), which is below that of most thermoplastics and some metals. The tensile modulus is increased fivefold. Flexural, tensile and compressive strengths are doubled. Mold shrinkage is reduced, making it possible to produce very precise parts.
