1mm Epoxy Fiberglass 3240 sheet

Product Description

Product Description
Product Description Yellow 3240 fiberglass PCB laminate sheet is a thermosetting industrial laminate consisting of a continuous filament glass fibermaterial with an epoxy resin binder. It has characteristics of high strength, excellent electrical properties and chemicalresistance not only at room temperature but also under humid or moist condition. The different between FR4 and G10 is that FR4 has the flame retardant property which meets the UL94 V-0 standard. And the G11 ishigher temperature resistant version of G10.The most versatile all around laminate grades are continuous glass woven fabricimpregnated with an epoxy resin binder. Epoxy resins are among the most versatile and widely used plastics in the electronicsfield, primarily because water absorption is virtually nil, rendering it an outstanding insulator.ApplicationFor Electric transformer:* High mechanical & electrical strength* Excellent rigidity & dimensional stability* Good dielectric properties* Low water absorption* Flame resistance * Tighter thickness tolerance* Flat and straight panel* Smooth and clean surface.* Easy to machine* Great properties, reinforced, smooth surface* Stable electric insulation performance,good flatness.ItemUnitValue (A/B)Densityg/cm31.90~2.30Martens heat resistance(LW)≥°C200Flexural strength ≥MPa400/200Tensile strength ≥MPa350/250Bonding ≥N5680Impact strength ≥KJ/M2150/100Surface resistivity ≥Ω1×1013 /1×1011Volume resistivity ≥Ω.cm1×1013 /1×1011Insulation resistance parallel tolamination ≥Ω1×1010 /1×108Loss tangent, 50Hz ≤0.05Transformer oil at 90±2°C ≥KV/mm22/20Transformer oil at 90±2°C ≥KV30Laser Cutting Services
