UV TEST & QUALITY
Lead in Raschel Protection Textile Manufacture since 1996.
Follow Quality Standard ISO9001 in production
We used the Extrusion Grade HD5000s Raw Material.
The Density is 0.954g/cm3 and Melt Flow Rate is 0.80g/10min.
which offers good balance of processability, high production rates, excellent tenacity and good appearance.
It is recommended for monofilament or yarn applications.
We add UV stabilizers and antioxidants to the formulation to help Polymer Netting resist oxidation and UV damage.
We have several formulations for worldwide different areas.
HALS: Tinuvin 783, Chimassorb 2020,
UV absorptions: Tinuvin 326 and so on.
After the production, We make the UV and Aging Test for yarns and polymer netting fabrics.
The Test Lamp: UVA340 1.55w/㎡/nm.
The Test Standard：ASTM G154-06 Cycle7.
The UV Resistance @1000hrs, @2000hrs
We also have field exposure tests to simulate the real aging environment of products.
The experimental site is located in Yunnan Province, China.
The altitude is more than 2,000 meters,
The annual sunshine time is more than 2,500 hours.
Solar radiation is 150KLY
Tensile Properties of monofilament and fabric are very important,
Our QC team compares the strength from monofilament, finished fabric, and after UV aging test.
The tensile test follows the test standard ISO 13934-1.
Pure High-Density Polyethylene, High Tenacity( 1 Den>5.5g)
Infrared heat insulation reflection and ultraviolet reflection are two important performances of Climate Screen and Agrotextiles.
We test these two properties through special testing equipment to ensure the excellent performance of the product to meet customer planting needs
