The company has recently completed a technical upgrade of its aluminum foil faced rubber-plastic insulation pipe series. By thermally laminating an aluminum foil protective layer, the product’s weather resistance, protection and moisture-proof performance have been further improved. The pipe is made of closed-cell foamed NBR-PVC rubber and plastic, with a plain aluminum foil or reinforced aluminum foil surface. It can also be made into a self-adhesive split aluminum foil type, forming an integrated structure of insulation and protection. Compared with ordinary black rubber-plastic pipes, the aluminum foil faced version is more suitable for outdoor, exposed and humid environments.
The upgraded pipe has low thermal conductivity and stable heat and cold preservation performance. It reaches Class B1 flame retardant grade, self-extinguishes after removing from fire, produces low smoke and no dripping, and operates from -40℃ to 105℃. The aluminum foil layer reflects radiant heat, enhances vapor barrier performance and reduces the risk of condensation dripping. It also resists UV rays, aging and oxidation, and is less likely to crack or powder after long-term outdoor exposure.
The series is now widely used for overhead outdoor HVAC pipelines, air source and solar heat pump pipelines, exposed central air conditioning lines, hot water insulation pipes and outdoor industrial pipelines. The technical department said the upgrade focused on improving the bonding strength between the aluminum foil and the rubber-plastic substrate.
