I. Advantages of UHMW plastic dock fender screen:
1. UHMW plastic dock fender screen allow vessels to glide easily along the surface, protecting hulls and dock structures. Doesn't mar ships, "grabbing" like rubber or wood. Sheds mussels and barnacles with minimum cleaning. Impervious to marine bore worms.
2. Wear-Resistant Surface
UHMW plastic dock fender screen outwear hardened steel. Cuts hour-glass wear on pilings from vertically moving "camels".
3. Nil Water Absorption.UHMW plastic dock fender screen no swelling or deterioration from water permeation.
4. Chemical- and Corrosion-Resistant.UHMW plastic dock fender screen withstands salt water, fuel and chemical spills. Chemically Inert does not leach chemicals into waterways, disturbing fragile ecosystems.
5. Performs in Weather Extremes.Sub-zero conditions do not degrade performance. UHMW plastic dock fender screen retains key physical properties to -260 centigrade. UHMWPE material is UV-resistant, which increases wear life in seaport exposures.
