by:Ventech     2020-12-07
Our company introduces the world advanced continuous production of rigid polyurethane foam production line, the proprietary technology and formula, the production of flame retardant, trumpets, environmental protection, energy saving heat preservation material - - - - Polyurethane ( PIR) Energy-saving insulation board and polyurethane composite panels, starting from the date of production to strengthen technological innovation, constantly improving product quality, to provide both energy saving and safe trust products, determined to make contributions to national cause of energy conservation and emissions reduction.



fireproof performance

rigid polyurethane belongs to thermosetting materials, low in da 100 ℃ the phenomenon of flow is not going to happen, adhesion, good thermal stability, and hard foam polyurethane and carbonized layer surface in the process of combustion, can effectively prevent fire spreading; And polyurethane board type belongs to thermoplastic materials, thermal deformation temperature of 70 ~ 80 ℃, 100 ℃ which meet the melting temperature, and flow of polystyrene in the combustion process occurs, flashover phenomenon, intensifying the fire from spreading.



weather can

A grade polyurethane composite board weatherability, freeze-thaw resistance, impact strength, water quantity and water vapor permeability, not accord with GB50404 - loss of flow density 2007 'hard foam polyurethane insulation technology of fire prevention engineering.

A grade polyurethane composite board 80 times after hot/cold rain cycle and five cycle, surface crack, pulverization, flaking off.

I company specializing in the production of pu heat preservation material, our products represent the heat preservation material industry at advanced technology level, leading the industry development direction, and is widely used in building energy efficiency and pipeline, storage tank, the wall heat preservation and heat insulation, LNG ship insulation, high-speed trains and other industrial and military fields, meet the needs of the clients order at any time. Welcome new and old customers to inquire or to choose and buy!
