Jute (including kenaf) was an important foreign exchange earner for the producing countries during '60s. Even during the '70s, jute was an important commodity for most of the producing countries. However, during the '80s, bulk handling techniques and synthetic substitutes entered the market and jute started losing its predominant position in the market.
polyethylene(PVC) geomembrane, as a high performance waterproof and impermeable material, has many remarkable advantages. Thickness: 0.1mm-3mm Width: 2m-6m Color: Black/White/Other colors Following is our PVC geomembrane Thickness 1.6mm spceifications: Tensile Strength (vertical and horizontal): 20MPa/mm Elongation at Break (vertical and horizontal): 580% Right-angle tearing strength (vertical and horizontal): 180N/mm Water vapor permeability coefficient: Using temperature range: +70â??~ -70â?? Puncture strengthâ?¥360N Water impervious: 100% Root resistance: 100% Difference Between PVC Geomembrane and HDPE Geomembrane PVC geomembrane and HDPE geomembrane have significant differences in physical properties, treatment difficulty, joint treatment, puncture resistance, and resilience to deformation. Physical Properties and Suitable Environment: PVC membrane: relatively soft and easy to bend, suitable for general waterproofing projects, swimming pools, and wastewater treatment, etc. HDPE membrane: has higher strength and wear resistance, suitable for engineering projects with higher strength and durability requirements, such as water conservancy projects and landfills. Handling Difficulty: PVC membrane: Due to its flexibility, we can make seams in controlled factory conditions, typically requiring fewer on-site seams than HDPE geomembrane. HDPE membrane: Handling in cold weather conditions can be challenging and requires sewing outdoors. Puncture Resistance: PVC membrane: It is harder to penetrate than HDPE and has high elongation characteristics, allowing it to adapt to site changes without reinforcement. HDPE membrane: While it has elasticity, it becomes plastic after exceeding its yield point and no longer has elasticity. Deformation Recovery: PVC membrane: Most of the deformation can be recovered, with a high tensile elongation, suitable for engineering projects with larger design strain limits. HDPE membrane: Deformation after exceeding the yield point cannot be recovered, and the material properties will change. We should select the appropriate geomembrane according to the specific project requirements and the use environment. HDPE geomembrane is suitable for projects that require high strength and durability, while PVC geomembrane is suitable for general waterproofing projects and water treatment.

Roofing Felt (Aluminum covered) Consist of a polyester fleece, impregnated by oxidized bitumen .The exterior side is covered by an aluminum layer and the inner side by nylon ,the aluminum layer reflexes more than 85% of heat and protects the main layer of the roofing felt against ultraviolet ray. This product is a very good cover for buildings roof . Roofing Insulation (Normal Isogum) Consists of a polyester fleece and a fiberglass tissue layer, which are impregnated by bitumen The exterior side is covered by mineral powder and the inner side by nylon. It is suitable to insulate roofs, kitchen, floors, baths, building foundations, swimming pools and cisterns.
PANZHU WRAP Breathable Membrane HP-F49 Enhanced The principle of PANZHU WRAP Breathable Membrane: Waterproof breathable working principle can be divided into two kinds-- microporous and hydrophilic groups, PANZHU WRAP waterproof breathable membrane is using the former. Due to the huge difference of diameter--- the minimum diameter of the water droplets 20 microns and the water vapor only about 0.0004 microns , water vapor can go through the microporous membrane easily.While because of the effect of surface tension, liquid water cannot pass the microporous membrane.Thus prevent the infiltration of water and make the breathable membrane waterproof.
Waterproof: PANZHU WRAP breathable membrane can reach the EU standard of European Union. The water-proof performance can bear two meters high water column for 24 hours. The water-proof performance is excellent Air tightness: PANZHU WRAP breathable membrane can reach the standard of use Permeability: Water vapour transmission of PANZHU WRAP breathable membrane reaches the international standards of 500 g / ã?¡. 24 h, equivalent to 29.2 of the U.S. perm, Canada's 1665ng/Pa/s/m². Durability: PANZHU WRAP breathable membrane is made of three layers.The upper and lower outer layers are protective layers, which helps the breathable membrane to have good tensile strength and anti-slip, so that it is suitable for sloping roof.
