Sur-Seal, Inc. 7530 is the most chemically inert of all plastics which complies with USFDA legislation for safe use with food and is one of the most versatile plastics known to man
Sur-Seal, Inc. 7530 has excellent thermal insulation and electrical reliability. This is true at high radio frequencies, making it suitable for use as an insulator in cables and connector assemblies
Sur-Seal, Inc. 7530 has a wide thermal range with a maximum temperature limit of 500 Degrees F and minimum of 328 Degrees F. PTFE will insulate to 500 volts per mil
Sur-Seal, Inc. 7530 has exceptional mechanical toughness with superior anti-stick, low frictional properties, and long term weather ability. PTFE is both high impact and tearing resistant
PTFE is unaffected by most corrosive liquids, vapors and gases, and conforms to both FDA and AMS specifications
Sur-Seal, Inc. 7530 (polytetrafluoroethylene) is a high molecular weight polymer and one of the most versatile plastics known to man. Virgin PTFE sheet can handle virtually all chemicals in the 0-14 pH range with the exception of molten alkali metals and elemental fluorine. It is suitable for service at temperatures from the cryogenic range up to 500 Degrees F. Sur-Seal, Inc. 7530 is particularly recommended for applications in the food and beverage industry where high purity materials are required. It is also used where contamination or discoloration of flow media cannot be tolerated. The coefficient of friction of plastics is usually measured against polished steel. PTFE's resistance to van der Waals forces means that it is the only known surface to which a gecko cannot stick. In fact, PTFE can be used to prevent insects climbing up surfaces painted with the material and is so slippery, that insects cannot get a grip and tend to fall off. For example, PTFE is used to prevent ants climbing out of formic aria. Because of its superior chemical and thermal properties, PTFE is often used as a gasket material. PTFE sheets are used in the production of butane hash oil due to its non-stick properties and resistance to non-polar solvents.
