RIJER INDUSTRIAL CO.,LTD
Feature of Acrylic
1. Excellent transparency : The light transmittance can reach to 93%.
2. Good chemical and mechanical resistance.It is the best choice to be applied into construction and outdoor sign etc.
3. Non-toxic and environment -friendly.
4. Light weight: less than half as heavy as glass.
4.Stable color under outdoor exposure. The acrylic sheets can withstand the erosion of sunshine, wind, snow and rain etc.
