How to judge the merits of the universal support
The emergence and promotion of universal support in China is also a matter of recent years。 Now there are several manufacturers and sellers in the interior of the country。 In general, the products that appear in China now are ice fires, and the best quality is Hangzhou than model support building materials; The rest are mainly several manufacturers in Jiangxi, but they all produce low grades and low grades。 The materials used are low prices and low standards of return PPs。 The mold production level is very poor。 The appearance of the product is too poor for the structure process and the quality is not guaranteed。 Only some customers who only talk about prices and do not require quality will use it。
At present, the most cost-effective universal support device in the market is a product made of PP+PA modified materials. After use, the material used for its products is -35 degrees cold resistance and 100 degrees high temperature resistance. Other manufacturers use PP materials or recycled PP materials. After enquiry, PP+PA modified materials have much better performance than recovered PP materials, and the market price is also higher.
