Bellows Materials
Commonly Used Materials:
Polyurethane: Comes in material thickness from .005 to .040. Temperature Range -60° F to +225° F. Very resistant to oils, water, ozone,ultraviolet. Very high abrasion resistance and has high tensile strength.
PVC: Comes in material thickness from .008 to
. 020.
Temperature Range from +32° F to +250° F
Better resistance to acid.
Neoprene Coated Nylon: Temperature Range -60° F to +250° F Resistance to oil and water.
Hypalon Coated Nylon: Temperature Range -60° F to 300° F.
Resistance to a wide range of chemicals.
Aluminum Coated Fiberglass: Temperature Range -l00° F to +550° F.
Resistance to very high temperature.
Teflon Coated Fiberglass: Temperature Range -l00° F to +500° F. Used in applications where specific
chemical attack makes other materials
unsuitable.
Silicone Impregnated Fiberglass: Temperature Range -60° F to +550° F.
Resistance to high temperature.
