Rubber plastic foam pipe PVC/NBR rubber plastic foam heat preservation material is an environmental protection product produced with our fully automatic production line based on the most advanced technology introduced by our company from abroad . The main features of the product are closed-cell foam structure , low coefficient of heat conductivity ;It has excellent heat insulation effect and can reduce power consumption; The closed-cell foam structure and compact coat makes it hard for vapor to permeate and makes low water absorbability; The product is flexible and this greatly facilitates construction and installation; The product looks elegant and clean; With wide ranges of applicable temperature (-40 to 120) and good weather resisting property ,the product is durable ;Unique fire retardant formulation makes the material have excellent fireproof and fire retardant effect. Owing to its excellent general properties the product has found wide application in construction, light and textile, pharmaceutical ,chemical metallurgy and shipbuilding industries etc. The product is largely used on water and refrigerant tubing/pipelines of air conditioning system for cool preservation(to prevent moist) and heat preservation (to avoid heat loss),which has obtained ideal result of application. 1) Low conductivity factor The coefficient of heat conductivity of this material is 0.034w/m.k at an average temperature of 0,but its coefficient of surface heat liberation is high , therefore, with the same external conditions, to use this product in less than half-value thickness of other heat insulation materials could reach the same heat insulation effect, thus reducing ceiling void and cutting down investment . 2) Closed pore foaming It is hard for vapor in external air to penetrate into the material ,which has excellent ability of vapor penetration resistance ,thus it is no need to add vapor insulation layer on the outer surface 3)Good fire-blocking There is a lot of retardant and smoke damping stuff in this material. When burning the smoke concentration is very low. The material does not melt .The material has self-extinguishing property. According to GB8624-1997 Classification Method of Combustibility of Building Materials, this material is assessed as class B1 nonflammable material ,thus safe and reliable application of the material is ensured. Benefits: 1. puts you in control of the temperature 2. provides good sound insulation qualities. 3. provides excellent fire resistance 4. reduce noise transfer, sound absorption. specification of rubber insulation foam pipe inner diameter:6mm-108mm wall thickness:5mm 9mm 15mm 20mm 25mm 30mm Technical specification of rubber insulation materials ItemSpecification Temperature-50temp.-105temp.
