полиэтилен

polyethylene foam 1 Independent closed cell cross-linked structure BHLONG foam belongs to macromolecule environment-friendly new material which has the lowest heat conduction and water vapor permeability by extrusion cross-linked foam.so the product has excellent thermal functionanti-water functionphysical and chemical character. 2 Thermal function BHLONG foam has the lowest heat conduction(0.032-0.038w/m..k), which reduces the lost of the calorific capacity .long-time usage can lower the energy expenditure and the cost. 3 Anti- aging,corrosion-resistant BHLONG foam has excellent anti-aging,chemical-resistant function.The effloresce aging and rime by water vapor permeability cannt rust the tube wall.The life-usage can achieve more than 20years. 4 The beautiful appearance BHLONG foam has soft and smooth texture,beautiful appearance by knurling compound. 5 Environment-friendly and energy saving characters BHLONG foam main material is polythene.Molecular formula is CH2-CH2 which is non-contamination.the advantage of chemical-resistant is in the top position. 6 Fireproof and smoke-resistant BHLONG foam has perfect flameproof function which cannt result the flame spread.The smoke density is very low,so it cannt result the hazardous material and accord with the standard of national GB/T8624.Applying permanence aluminum foil compound technology,not only make the aluninum foil compond material incombustible and beautify,but also achieve the enduring character. 7 Excellent weather-resistant character BHLONG foam appear the perfect stability under the low temperature ciuculation(-40-80),especially it is under the cold climate circulation. 8 Excllent shrink-resistant and buffer function BHLONG foam have the excellent softness elasticity and buffer function
