万能支撑器的优劣如何判断　

万能支撑器在国内出现及推广也就是近几年的事，现在国内陆继出现了几家生产厂家及销售商。总体而言，国内现在出现的产品是冰火两重天，质量最好的如杭州比模特支撑建材；其余的主要是江西有几家生产厂家，不过他们生产的都是低档低，用材都是低价低标准的回料ＰＰ，模具制作水平很差，产品外观对结构工艺太差，质量得不到保障，只有一些只讲价格，不要求质量的客户才会用，性价比一般。

　　现在市场上性价比最高的万能支撑器要属采用PP+PA改性材料制造的产品，经过使用，其产品所用材质耐寒零下35度，耐高温100度。而其他厂家用的都是ＰＰ料或者是回收PP料，经查询，PP+PA改性材料比回收ＰＰ料的性能好得多，市场价格也更高一些。

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.
