Description:
Viton AL-300 is an “AL-family” gum polymer that demonstrates improved processing when compared to its precursor Viton B-70N. This gum provides:
• Lower viscosity
• Improved mold flow
• Better mold release
• Less mold fouling
• Improved compression set resistance
• Good low temperature characteristics
Viton AL-600 is an “AL-family” gum polymer that demonstrates improved processing when compared to its precursor Viton B-70N. This gum provides:
• Higher viscosity
• Improved mold flow
• Better mold release
• Less mold fouling
• Improved compression set resistance
• Good low temperature characteristics
Viton AL-276C and Viton AL-576C fluoroelastomers are two precompounds intended for use in applications that require low temperature flexibility similar to Viton B-70. Viton AL-276C and AL-576C have a nominal Mooney viscosity (ML 1+10 at 121 °C [250 °F]) of 20 and 50, respectively. Both precompounds are based on 66% fluorine copolymer gums and designed to give the best balance of low temperature flexibility, automotive fuel resistance, and heat resistance.
These precompounds are based on improved rheology polymers (IRP) and contain a proprietary process aid package that has been developed to impart improved processing characteristics over products like Viton B-70. Typical applications for these materials are automotive fuel injector O-rings and other molded parts that require low temperature flexibility similar to Viton B-70.
By blending Viton AL-276C with Viton AL-576C,compounds may be tailored to give the viscosity
most appropriate for the production equipment (i.e.,compression, transfer, or injection molding) and tooling geometry. These precompounds have been designed to provide more efficient, cost-effective processing with reduced scrap and longer periods between mold cleaning.
Overview:
Viton AL-type fluoroelastomers are gum terpolymers comprised of hexafluoropropylene (HFP), vinylidene fluoride, and tetrafluoroethylene (TFE). They are ideal for applications where resistance to compression set and the ability to return to original thickness after a compression load has been applied are essential.
The Viton AL family of products is widely used in fuel systems, including:
Fuel injector O-rings
Injection and transfer molding of O-rings, gaskets, and other sealing devices
Extruded cords, profiles, and tubing
Solution coatings of fabrics and other substrates
Features and Benefits
The “L” designation in Viton AL indicates that the polymer provides slightly improved low-temperature flexibility characteristics versus other polymers within the same family.
Viton AL-type fluoroelastomers offer:
Improved mold flow
Better mold release
Less mold fouling
Improved compression set resistance
Good low temperature characteristics
Viton Terpolymers
FLUOROELASTOMERS WITH BETTER CHEMICAL RESISTANCE
In addition to the heat and chemical resistance offered by all Viton fluoroelastomers, the Viton terpolymer family offers excellent processing, rheology, and physical properties, as well as significant improvements for resisting chemical attack.
