Hard polyurethane insulation board/sandwich type polyurethane insulation board is used in all kinds of building exterior wall, roof insulation, as well as refrigeration facilities, building doors and Windows, industrial equipment and special vehicles insulation; It is an emerging organic polymer thermal insulation/thermal insulation material.
BBS rigid polyurethane insulation board thickness 20-55mm, fixed width 1200mm, length optional, polynitroxide foam material density is generally 45kg/m3, according to demand can be adjusted to 70kg/m3 density. The surface layer material of rigid composite polyurethane insulation board is divided into roller coated aluminum plate (thick 0.8mm), color barium plate (thick 0.25-0.50mm), imitation marble aluminum plate and other combinations.
Features:
1.When the rigid foam density of polyurethane is 35~70kg/m3, the thermal conductivity is only 0.17~0.023w/(mk). In the current practical application of thermal insulation materials, thermal performance is good, the lowest thermal conductivity. In the application of building external wall insulation, 10 mm polyurethane insulation board is roughly equivalent to 400 mm clay brick wall insulation effect.
2.Compared with other polymer insulation materials, hard polyurethane insulation board has compression, shear and tensile strength, which can adapt to the normal deformation of the base material associated with it without cracks, empty drums and other phenomena.
3.Polyurethane insulation board has strong adhesion or composite properties with concrete, clay blocks, metal, wood, rubber and glass.
4.Because the closed cell rate of the polyurethane insulation board is more than 93%, the water absorption rate is less than 3%, and the waterproof effect is good.
5.Hard polyurethane insulation board can be used normally between the temperature of -40~+90℃(metal surface composite polyurethane insulation board temperature adaptation range is high), high dimensional stability, good weather resistance and chemical stability.
6.Adding flame retardants in the production process of polyurethane insulation board can adjust and improve the combustion resistance of polyurethane vinegar material, and achieve the effect of self-extinguishing from fire and carbonization of surface combustion.
7.Non-toxic and non-irritating, no free formaldehyde, toluene and xylene and other substances precipitation, can be directly used in the living environment.

特點:
1、在聚氨酯硬泡密度為35~70kg/m3時，導(dǎo)熱系數(shù)僅為0.17~0.023w/(mk)。在目前實際應(yīng)用的保溫材料中熱工性能好，導(dǎo)熱系數(shù)最低。在建筑外墻保溫應(yīng)用中，10毫米聚氨酯保溫板大致相當(dāng)于400毫米黏土磚墻的保溫效果。
2、相對于其它高分子保溫材料，硬質(zhì)聚氨醋保溫板具有壓縮、剪切和拉伸強(qiáng)度，可適應(yīng)與之聯(lián)系的基層材料的正常變形而不產(chǎn)生裂縫、空鼓等現(xiàn)象。
3,聚氨酯保溫板具有與混凝土、粘土砌塊、金屬、木材、橡膠及玻璃等強(qiáng)力粘貼或復(fù)合的特性。
4、由于聚氨醋保溫板的閉孔率達(dá)93%以上，吸水率低于3%，防水效果好。
5、硬質(zhì)聚氨醋保溫板可在溫度-40~+90℃(金屬面復(fù)合聚氨醋保溫板溫度適應(yīng)范圍高)之間正常使用，尺寸穩(wěn)定性高，耐候性及化學(xué)穩(wěn)定性良好。
6、在聚氨酯保溫板生產(chǎn)過程中加入阻燃劑可調(diào)節(jié)及提高聚氨醋材料的抗燃燒性能，達(dá)到離火自熄和表層燃燒炭化的效果。
7、聚氨醋保溫板制成品無毒無刺激性，無游離甲醛、甲苯和二甲苯等物質(zhì)析出，可直接用于居室環(huán)境。
