1.看外观

1. Look at the appearance

查看橡塑绝热材料的表面，如果表面颜色均匀有光泽感，表面无气泡、麻点、细纹、起皮等现象，呈现出光滑平整、外形美观，质量则属上乘；反之，如果表面颜色暗哑，易出现小细纹，随手一抠就破，则质量低劣。

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.看导热系数

2. Check the thermal conductivity coefficient

导热系数是橡塑绝热材料材料基础的性能指标，决定着材料保温性能的优劣。导热系数越小，材料的保温性能就越好，相反，导热系数越大，材料保温的性能就差，同时还会造成能量的大量损耗。

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.看湿阻因子

3. Check the moisture resistance factor

湿阻因子是一个衡量绝热材料抗水汽渗透的一个因素，其值越大则说明材料的抗水汽渗透能力越强，使用寿命也就越长。

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.看防火等级

4. Check the fire rating

按照标准GB8624可将建筑材料的防火等级分为以下几种：B1级难燃、B2级可燃、B3易燃。市场上除了传统的无机材料可以达到不燃以外，其他的产品均在B1级水平以下，橡塑绝热材料要达到B1级难燃还是颇有难度的。

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.看使用寿命

5. Check the service life

橡塑绝热材料具有的耐天候、抗老化、抗严寒、抗干燥、抗潮湿、抗紫外线、耐臭氧、不变形等特性，市场上一般橡塑绝热材料的使用寿命大多为15年左右，而好的橡塑绝热材料可使用25年，比空调的使用寿命还要长。

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.
