Polyurethane composite board performance and parameters
coefficient of thermal conductivity: 0. 018-0. 024w/（ 该调查)
low coefficient of thermal conductivity, 5 cm thick composite board is equivalent to 100 cm thick concrete heat preservation effect
obturator rate: 97% waterproof and moistureproof, not because of the increased moisture absorption coefficient of thermal conductivity, metope also won't ooze water
green: good polyurethane foam composite panels pass through high pressure, is the product conforms to the international convention on the ozone layer protection, and comply with European environmental standards. Do not contain formaldehyde, from microorganism erosion.
stability: good polyurethane composite panels above the compressive strength of 180 KP, plate temperature resistant performance is good, not out of shape.
flame retardant performance: good after national fireproof construction material quality supervision inspection center, the indicators of GB8624B1 level. Belong to the thermosetting materials, coke burning ashes, from self-extinguishing fire, do not drop, don't spread.
weatherability. Durable after more than six months of weathering test, the performance is stable, can with the building life.
I company production of polyurethane composite panels with the national standard, and our company is committed to create high quality products for the vast number of consumers to use, welcome to choose and buy.
