insulator

Medium and high votage resistance LSR insulator 1) Basic model:LIM2930A/B and LIM2945AB 2) Product Description 2-part liquid silicone rubber,which is suitable for injection or extrusion molding with tracking resistance 1A 3.5 grade, mixing ration of parts A:B=1:1,withstanding middle and high voltage, catalyzed by platinum .The appearance of A is transparent and B is gray. 3) Key Features Outstanding anti-ageing High elongation and low tension set High tear strength Excellent tracking resistance Excellent electric performance Rapid vulcanization 4) Applications Indoor cold shrink and terminal, tie-in and jacket etc suitable for injection and extrusion molding Medium and high voltage resistant cable accessories. 5) Storage Correctly stored in its original closed container at room temperature (max 30). SQUARE® LIM2930/2945AB has a shelf life of 12 months. The ready to use LIM2930/2945AB should be kept tightly closed, if doesnt , it will affect the shelf life.6) How to use Ready-to-use mixturescomponents A and Bare fed directly to injection molding machine from the original containers by means of a metering end mixing unit called static mixer The mixtureat the mixing ratio 11 is injected into the heated mould. The shelf life is 7 days (23°C) after mixing. The pipline should be cleared if the machine wont work for long time.7) Packaging SQUARE®LIM2930A/B and LIM2945A/B are available in 20kgs pails or 200kgs drums. 8) Typical Properties Uncured PropertiesItemStandardUnitLIM2945A/BLIM2930A/BViscosity(Y=10.0S-1)DIN53479Pa.s11001200AppearanceA: Transparent B: GreySolid content%100100Cured PropertiesSpecific GravityDIN535051.131.12Shore A hardnessDIN53 504ºA3530Tensile strengthDIN53 504Mpa9.08.0Elongation at breakASTMD624B%800800Tear resistanceD412N/mm2825Tension set :Keeping 200% extension for 48 hrs at 50D412%≤3.03.0Volume ResistivityGB/T1692-1992Ω.m10151015Dielectric constant (50Hz)GB/T1691-1982.82.8Dielectric StrengthGB/T16952005Kv/mm2626Tension set :Keeping 300% extension for 15 hrs at 120GB/T1692-1992%8.08.0Dissipation factor(50z)GB/T1691-1980.00160.00169) Remarks The viscosity is tested by NDJ-79#Rotary viscosimeter Condition of productioncuring 10 minutes at140°C,post cure4hrs at 200°C GB is Chinese national standard These figures are for reference only, Please contact us for detail
