(-70°C to +220°C) (-94°F to +428°F)
Varglas Viton® 231 sleevings are braided fiberglass/modified Viton® composite with exceptional physical and electrical properties. It has excellent abrasion and cut-through resistance and offers improved flexibility throughout a wide operating temperature range. Its resistance to solvents, both aromatic and aliphatic; fuels, including JP-5; and oils, placing this fluoroelastomer above other available polymer-coated fiberglass braids.
VARGLAS ES-4400 SILICONE RUBBER
R-A-1 | R-B-1 | R-C-1
(-73°C to +220°C) (-100°F to +428°F)
Varglas ES-4400 silicone rubber sleevings are produced by curing a specially compounded silicone gum with a select catalyst on a continuous length of fiberglass braid. Most silicone rubber is characterized, chiefly, by its capability of performing satisfactorily at elevated temperatures. Varglas ES-4400 silicone rubber, in addition to providing superior dielectric and thermal protection, at less weight, was developed to meet unusual fluid and flame resistance requirements. Its high temperature performance places it in a 220°C classification.
VARGLAS SILICONE RUBBER
H-A-1 | H-B-1 | H-C-1 | H-C-2 | H-C-3
(-73°C to +200°C) (-100°F to +392°F)
Varglas silicone rubber sleevings are produced by coating braided fiberglass with a high-performance silicone rubber that is extremely flexible and exhibits unusual toughness and abrasion resistance. In addition to having a Class 200°C rating, its brittle point of -73°C also suggests its use in a wide range of applications requiring resistance to temperature extremes.
VARGLAS SR-9400 SILICONE RUBBER
(-78°C to +200°C) (-108°F to +392°F)
Varglas SR-9400 silicone rubber sleeving is produced by coating braided fiberglass with a highly crosslinked, high performance silicone rubber that is both flame resistant and extremely flexible. It is a Class 200°C sleeving that, in addition to excellent electrical insulating properties, also displays outstanding low-temperature operating capabilities.
VARGLAS SILICONE RESIN 500
(-70°C to +220°C) (-100°F to +428°F)
Varglas silicone resin 500 sleevings are a fiberglass braid with a silicone composite coating. Silicone resin 500 is a more flexible product designed to conform to sharp bends. This sleeving is best in areas where design requirements specify superior moisture, heat and radiation resistance. In addition to its Class 200°C rating, it also exhibits exceptional low temperature properties. Varglas silicone resin 500 sleevings are available in four grades where standard silicone resin is in Grade C-3.
VARGLAS A397 & 343 ACRYLIC
F-A-1| F-B-1| F-C-1| F-C-2 | F-C-3
(-25°C to +155°C) (-13°F to +311°F)
Varglas A397 and 343 Acrylic sleevings are produced by curing a modified acrylic resin on a continuous fiberglass braid, with A397 Acrylic best characterized by its flexibility. Both are resistant to most acids, organic solvents, oils and water and exhibit fair resistance to alkalies. They are compatible with modified polyester, acrylic, epoxy, phenolic and formvar wire enamels. Designed to perform for long periods of time in a 155°C range without loss of any electrical or physical properties.
B-A-1 | B-B-1 | B-C-1
(-34°C to +130°C) (-29°F to +266°F)
Varflo sleevings are braided fiberglass coated with a modified polyvinyl chloride resin. Superior plasticizers, along with the best flame retardants and fungicides, make Varflo an outstanding Class 130°C sleeving. It displays outstanding flexibility and resistance to oils, solvents and moisture. Varflo has exceptional shelf life and will not lose dielectric strength when subjected to severe twisting.
B-A-1 | B-B-1 | B-C-1 | B-C-2
(-34°C to +130°C) (-29°F to +266°F)
Varfil sleevings are braided fiberglass coated with polyester-modified, polyvinyl chloride resin. Thanks to the composite coating, Varfil sleevings have improved properties over standard polyvinyl plastisol coatings with regard to chemical compatibility and solvent resistances. Varfil resists swelling in oil, xylol and trichloroethane making it an excellent fit in Class 130°C. Some users prefer the slight degree of firmness found in Varfil when compared to Varflo.
B-A-1 | B-C-1
(-25°C to +130°C) (-13°F to +266°F)
Varglas Hermetic sleevings are produced by coating braided fiberglass with a highly-crosslinked, modified acrylic copolymer that is extremely flexible yet very tough and abrasion resistant. It is highly resistant to refrigerants, at both high and low temperatures, and compatible with potting compounds and varnishes. Varglas Hermetic sleevings offer good resistance to thermal shock and is unaffected by most common oils including xylol/paraffin oil (50/50 mixture by volume), refrigeration lubricants Suniso® 3-G (a mineral oil), Icematic® SW100 (a synthetic polyol-ester oil), and ZEROL® 150 (a synthetic alkylbenzene oil). It is also resistant to most solvents including methylene chloride, toluene, xylene and 1,1,1 trichlorethane. Designed specifically for hermetic motors, its “low extraction” levels of soluble materials protect against contamination, as well as clogging, within the compressor system.
Varglas Hermetic sleevings meets the requirements of NEMA TF-1, Type 2, and ASTM-D372.
