Manufacturers selling high-quality insulated rubber mats, rubber insulation board

Manufacturers selling high-quality insulating rubber mat, rubber sheet insulation manufacturers selling high-quality insulating rubber mat, rubber sheet insulation insulation pad insulation pads, also known as insulation blankets, insulation pads, rubber insulation panels, insulation sheet, insulating rubber mat etc., with a large volume resistivity and electrical breakdown resistant pads. For table or floor insulation material distribution and other workplace. Insulated rubber plate test :( to 8mm insulated rubber board, for example) 1. Appearance: 1) scar depth and height does not exceed the plastic sheet thickness tolerance 2) bubbles per square meter, an area of ??not less than 1cm bubble over five, any two the distance between the bubbles is not less than 40mm. 3) impurity depth and length does not exceed 1/6 of the thickness of the plastic sheet 4) edge uneven or spongy width not exceeding 10mm, length does not exceed 1/10 of the total length of the plastic sheet 5) did not crack 2. Hardness (Shore A) : 55-70 3. The tensile strength and elongation at break: 1) Tensile strength (Mpa) ≥5.0 2) Elongation at break ≥250% 4. elongation (150%) permanent deformation ≤25% 5 The hot air aging (70 ℃ * 72h): tensile strength decreased water absorption rate ≤30% 6. ≤1.5% 7. electrical insulation performance tests: 1) withstand voltage test: 25KV (RMS), keep 1min, there should be no breakdown 2) breakdown voltage test ≥35KV (RMS) is widely used in insulation pads substations, power plants, power distribution room, test roommate and wild live operations, mainly plastic type insulation materials, insulation pads upper and lower surfaces should be no harmful irregularities. Harmful irregularities is one of the following characteristics, namely the destruction uniformity, damage the surface smooth contour defects such as holes, cracks, local uplift, incision, mixed with conductive particles, creases, the gap, bump, ripple and casting marks . Harmless irregular refers to the production process of the formation of the surface irregularities.
