25% Glass Fiber Reinforced PTFE is a subcategory of Fluoroplastics. The additative is added by weight during the manufacturing process. Its elastic modulus ranges from 200 to 240 MPa. Its flexural modulus ranges from 190 to 235 MPa. Its tensile strength ranges from 2000 to 2700 MPa at break. Its compressive strength ranges from 1000 to 1400 MPa. Its elongation at break ranges from 200 to 300 %. Its hardness ranges from 60 to 70 Shore D. Its specific gravity ranges from 2.2 to 2.3. Its coefficient of thermal expansion ranges from 77 to 100 x 10^-6/°C. Its molding pressure ranges from 3 to 8 MPa.

Fluoroplastics, also known as PTFE, is a thermoplastic polymer. The most common trade name is Teflon. PTFE It has low mechanical strength and is expensive. It has very low coefficient of friction. PTFE is commonly used in applications needing excellent dielectric strength and chemical and temperature resistance.
