Coated sleevings are used to satisfy electrical, as well as, thermal, physical and chemical requirements. Generally, braided electrical insulating sleevings which have been continuously coated are characteristically identified with a temperature classification (thermal level at which sleeving can operate continuously) and a grade (defined through dielectric strength breakdown or puncture voltage) as follows:

Temperature Classification   DIelectric Strength Breakdown Voltage (Volts) (1)
  C Over 240°C     Grade Minimum Average Minimum Individual  
  S 240°C     A-1 7,000 (2) 5,000  
  R 220°C     B-1 4,000 2,500  
  H 200°C     C-1 2,500 1,500  
  F 155°C     C-2 1,500 800  
  B 130°C     C-3 No Dilectric Guarantee  
  A 105°C  

Notes:
(1) Conditioned for 96 hours at 23°C and 50% relative humidity
(C-96/23/50) before testing.


(2) For NEMA sleeving Types 3 (polyvinyl chloride coated), 4 (silicone resin coated) and 5 (silicone rubber coated), values are 8000 volt average and 6000 volt minimum individual.
         
Grade S - 240°C

>> Silicone 240 Rubber Class S-A-1

— High Temperature (240°C) Rubber with exceptional mechanical properties and flame resistance.

Grade R - 220°C

>> Varglas Viton® 231 Class R-A-1

— High-Temperature (220°C) Fluoroelastomer (silicone free) with superior flame and solvent resistance.

Grade F - 155°C

>> Varglas Acrylic 343 Class F-A-1

— Flexible Modified Acrylic Resin (155°C).

>> Varglas Acrylic 343 FR Class F-A-1

— Flexible Modified Acrylic Resin (155°C), flame-retardant .

>> Varglas Acrylic 343 MegaWall*

— Our standard Grade A Varglas 343 Acrylic sleeving is also available as Varglas MegaWall Acrylic Sleeving which is produced utilizing the same modified acrylic resin system, but with a minimum coating thickness of 0.020” that exhibits a dielectric strength of approximately 16,000 volts. This product enhancement also makes Varglas MegaWall Acrylic Sleeving ideally suited for use in systems and end products requiring extreme abrasion resistance.
