Appliaction

In addition to excellent electrical properties, weather resistance, ozone resistance and other properties, this product also has excellent low temperature resistance, radiation resistance, ablative resistance and self-extinguishing. This product can be used for a variety of electrical components as potting materials, but also as impregnated impression and release materials, a component of the binder. It can be used as bonding of all kinds of aircraft thermal insulation materials, spacecraft thermal insulation products, engine thermal insulation supplies, nuclear power radiation protection coating, for cold and burn resistance, heat aging and radiation resistance parts of the sealing ring, pad, pipe, bar and so on. It is still elastic under the low temperature condition of -120 ℃, adding a certain amount of heat resistant additives, suitable for ablative putty, coating and encapsulation can be used for special purposes.
