Tin tức của công ty về Pvc Pp Privacy Strip Panel Double Rod Fence Strip Roll Balcony Privacy Screen
This product is extruded from PP (polypropylene) or PVC material and is designed specifically for privacy screen roller blinds in double pole fence systems. Professional product data shows that its temperature resistance can reach -60 ℃ to+160 ℃ (PP material), suitable for extreme climates. The anti UV rating reaches level 7, and the performance is stable after 3000 hours of xenon lamp aging test. The material has a 100% opacity, achieving complete privacy shielding. In terms of physical performance, a double pole penetration design is adopted to enhance wind resistance. The tensile strength can reach ≥ 40MPa according to the GB/T 1040 standard, and the bending modulus is ≥ 2500MPa. The weight range covers 450-900g/㎡, with a thickness of 0.7-1.2mm to choose from. The standard specification is 19cm high by 35-50m long, and comes with 20-40 fixed buckles. It supports RAL/PANTONE color customization and flame retardant options.
1. Material selection: PP vs PVC
Select accurately based on climate conditions:
PP material: temperature resistance -60 ℃ to+160 ℃, bending modulus ≥ 2500MPa (stronger rigidity), UV resistance level 7, suitable for cold (Northeast) or high temperature (Xinjiang) areas, service life 8-10 years
PVC material: resistant to temperatures ranging from -30 ℃ to+70 ℃, with better flexibility (Shore A85 ± 5), tear strength ≥ 300N, suitable for mild climates, and priced 20-30% lower than PP
2. Wind resistance and structural verification
It is necessary to adopt a double bar through design (fixed with upper and lower double horizontal bars), which increases wind resistance by 50% compared to a single bar. Request to provide a wind tunnel test report to ensure that it can withstand a wind speed of 25m/s (level 9 wind). The included buckles should be made of stainless steel galvanized material, with a recommended quantity of ≥ 20 per roll and a spacing of ≤ 1 meter.
3. Performance data indicators
Tensile strength ≥ 40MPa (GB/T 1040)
Opacity 100% (ASTM D1003)
After 3000 hours of xenon lamp aging test (ISO 4892), the gray level is ≥ 4
Weight selection: Standard type 450-650g/㎡, reinforced type 700-900g/㎡
Flame retardant optional UL94 V-0 grade
Color support RAL/PANTONE customization, roll width adjustable at 19cm, length cut as needed.
Q: How does this PP material screen perform in the harsh winter of northern China?
Answer: Very stable. After experiencing two winters (with a minimum temperature of -35 ℃), the screen strips remained brittle and crack free, and maintained good flexibility. Its temperature resistance of -60 ℃ to+160 ℃ has been fully verified in practical use, far superior to ordinary PVC materials (which become brittle at -30 ℃).
Q: Is the double pole fixed structure really stronger in wind resistance?
Answer: Indeed. The balcony faces the seaside and has experienced multiple typhoons (with maximum wind speeds of 28m/s and winds exceeding level 10) without any detachment or deformation of the screen strips. The double pole penetration design increases wind resistance by more than 50% compared to single pole fixation, and the wind tunnel test standard of 25m/s is true and reliable.
Q: How does the color and material properties remain after long-term sun exposure?
Answer: Excellent performance. After 26 months of use, the dark gray screen strip showed no significant fading after exposure to strong ultraviolet radiation. The performance of its UV resistance level 7 and 3000 hour xenon lamp aging test has been verified, with no powdering or embrittlement of the material, and a tensile strength retention rate of>90%.
