1. About ASA film layer , We used to use 2 categories: 10#ASA and 30#ASA. The mainly function of this layer is to resist the corrosion of ultraviolet light, high heat, low cold, frost,
rain and snow with acidic or alkaline substances, and it is also the core element of the
color to maintain 5% fade in 10 years. (Tip: 30# ASA is better than 8#. )
2. The core material of the middle layer are Sodium Silicate and Nano - calcium.Our products
have better load resistance and impact resistance than the popular synthetic resin in the market.
This invention has Obtained a number of National patent certification.
3. The third layer, mainly divided into 3 categories, Basic; Heat insulation; Enhanced insulation. On
the basis of ensuring the load resistance, impact resistance and Abrasion resistance of the product,
the heat resistance and flame retardant performance are successively enhanced,which makes our
produtcts have longer useful life ---- 30-55 years. Please look at the below picture .We use three
colors to distinguish three different insulation layer.
