产品说明

DuPont™ Tefzel ® 2195 fluoropolymer is a premium-grade resin designed for use in rotational molding. To be effective as a rotational molding resin, Tefzel ® 2195 is a free-flowing powder, with controlled particle size, shape, and size distribution.

The properties of Tefzel ® 2195 in molded form are similar to other grades of Tefzel ® fluoropolymer resin.

Rotational molding is a favored process for making hollow parts (particularly large parts) or for parts with complex geometries. Depending on part design and processing conditions, Tefzel ® 2195 can also be used to rotoline items, whereby the Tefzel® binds to the inner surface of the part to form a lining.

Properly processed rotational moldings made from Tefzel ® 2195 provide the superior properties typical of the fluoropolymer resins: retention of properties after service at 150°C (302°F), useful properties at -100°C (-148°F), and chemical inertness to most industrial chemicals and solvents. Molded products have excellent stiffness and high ultimate elongation.

Statements, or data, regarding behavior in a flame situation are not intended to reflect hazards presented by this or any other material when under actual fire conditions.
