Fire prevention principle of HM-RS-PPS



Dingchang EM-RS-PPS seal is used to seal the thermoplastic pipe through the metal structure, which has the effect of watertight and airtight. We have added special fire retardant materials into the seal. This material will expand in volume when heated at high temperatures (such as fire) and block the gap outside the plastic pipe C. -In the event of a fire, when the plastic pipe starts to burn and melt, the opening of the seal will be completely closed and block the spread of fire and smoke through the seal to the other side of the metal structure
