So, this material products have more excellence.


More excellence for composite resin material.

Test report:
1) Temperature Endurance: Put sample into oven at 60 centigrade for 16 hours, then put it into cold storage at-40 centigrade for 2 hours, the result is: Expand rate 0. 35
4) Anti Aging: Put it into a temperature and wet equipment, use Xenon light at 60 centigrade + / ->5 centigrade and rain for 500 hours, its anti refraction strength is >3
