Tear Resistant (23 Series)

Tear Resistant (23 Series)

Tear Resistant (23 Series) are the strongest, most durable line of PTFE coated fiberglass belting

Description

Tear Resistant (23 Series)

The DuraFab® Tear Resistant belts are specially processed to increase their overall flexibility and tear resistance, thus making them the strongest, most durable line of PTFE coated fiberglass belting. These fabrics are manufactured from woven fiberglass substrates, leave a minimal fabric impression, possess an optimal PTFE (Fluon®) content, and have a proprietary additive for flexibility. DuraFab® Tear Resistant Belting has excellent flexibility and is ideal for use in small pulley and high-speed packaging applications.

DuraFab® PTFE Coated Belt Characteristics

DuraFab® Belts are engineered to retain the distinctive properties of PTFE; however, by adding a glass fabric to the matrix, AFC is able to obtain the added benefits of dimensional stability, excellent tensile strength and extremely low elongation (<1%). DuraFab® Belts have received USDA approval for food processing and handling, and are FDA compliant (21 CFR177.1550). In addition, the DuraFab® belts can operate in temperatures from -400°F (-240°C) under static conditions and -100°F (-73°C) under dynamic conditions up to 550°F (288°C).
