1.看外觀

1. Look at the appearance

查看橡塑絕熱材料的表面，如果表面顏色均勻有光澤感，表面無氣泡、麻點、細紋、起皮等現象，呈現出光滑平整、外形美觀，質量則屬上乘；反之，如果表面顏色暗啞，易出現小細紋，隨手一摳就破，則質量低劣。

Firstly, check the surface of the rubber insulation material. If the surface color is uniform and has a glossy feel, and there are no bubbles, pits, fine lines, peeling or other phenomena on the surface, it presents a smooth and flat appearance, with a beautiful appearance, and the quality is considered superior; On the contrary, if the surface color is dull and prone to small fine lines, which can easily break with just one pick, then the quality is poor.

2.看導熱系數

2. Check the thermal conductivity coefficient

導熱系數是橡塑絕熱材料材料基礎的性能指標，決定著材料保溫性能的優劣。導熱系數越小，材料的保溫性能就越好，相反，導熱系數越大，材料保溫的性能就差，同時還會造成能量的大量損耗。

The thermal conductivity is the most fundamental performance index of rubber insulation materials, which determines the quality of the material's insulation. The smaller the thermal conductivity, the better the insulation performance of the material. On the contrary, the larger the thermal conductivity, the worse the insulation/cooling performance of the material, and it will also cause significant energy loss.

3.看濕阻因子

3. Check the moisture resistance factor

濕阻因子是一個衡量絕熱材料抗水汽滲透的一個因素，其值越大則說明材料的抗水汽滲透能力越強，使用壽命也就越長。

The moisture resistance factor is a factor that measures the resistance of insulation materials to water vapor penetration. The larger the value, the stronger the material's resistance to water vapor penetration and the longer its service life.

4.看防火等級

4. Check the fire rating

按照標準GB8624可將建筑材料的防火等級分為以下幾種：B1級難燃、B2級可燃、B3易燃。市場上除了傳統的無機材料可以達到不燃以外，其他的產品均在B1級水平以下，橡塑絕熱材料要達到B1級難燃還是頗有難度的。

According to the standard GB8624, the fire resistance rating of building materials can be divided into the following categories: B1 level flame retardant, B2 level flammable, and B3 level flammable. Except for traditional inorganic materials that can achieve non flammability, all other products on the market are below B1 level. It is quite difficult for rubber insulation materials to achieve B1 level non flammability.

5.看使用壽命

5. Check the service life

橡塑絕熱材料具有的耐天候、抗老化、抗嚴寒、抗干燥、抗潮濕、抗紫外線、耐臭氧、不變形等特性，市場上一般橡塑絕熱材料的使用壽命大多為15年左右，而好的橡塑絕熱材料可使用25年，比空調的使用壽命還要長。

Rubber and plastic thermal insulation materials have excellent weather resistance, aging resistance, cold resistance, dry resistance, moisture resistance, UV resistance, ozone resistance, deformation resistance and other characteristics. Generally, rubber and plastic thermal insulation materials in the market have a service life of about 15 years, while good rubber and plastic thermal insulation materials can be used for 25 years, which is longer than the service life of air conditioners.
