Difference between ASTM & GB standard Geocell
No matter GB or ASTM standard Geocell, they have the same appearance. Same Height, welding distance, thickness, cell size, and expanded area size.
The difference between GB or ASTM standard Geocell is they use different raw materials, so they have different specification values.
GB standard Geocell uses recycled HDPE plastic, the seam peel strength is 10KN/m, and tensile strength is 16KN/m. Due to it being used recycled material, it only tests strength, not test more values. The quality is a little lower than the ASTM standard, but the price is more competitive. Due to the price being good, we sell very large quantity to customers in Vietnam, Indonesia, Thailand and the Philippines…
ASTM standard Geocell uses virgin HDPE material to produce, the seam peel strength is 14.2KN/m, and tensile strength is 22KN/m. This type of Geocell not only tests strength but also tests other values. Like Environmental stress crack resistance and OIT oxidation induction time. The quality is very good, so the price is a little higher than the GB standard. Most sell in the USA, Europe, Germany and Australia…
