What should I pay attention to when choosing APP waterproof coiled material?

There are many kinds of waterproof coiled materials, which are suitable for different waterproofing projects. Among them, APP waterproof roll has the characteristics of heat resistance and elongation, and so on. Then, in the choice of APP waterproofing membrane, what should pay attention to? How can I choose the APP waterproof roll that suits me? Let's take a look at it.

There is no drip in the case of type 1. plasticity at 110 degrees, and there is no drop in the shape of the plastic body at 130 degrees.

2., to test the tensile force and elongation of the coil, so that we can know the quality of the tire base.

3., determine the coil's use time is anti-aging ability.

The content of soluble substance in 4.APP waterproof coiled material will affect its waterproof impermeability.
