Plastics for chemical tanks and plants
The performance capacity of chemical tanks and plants is determined by many factors. High operating safety is required even at aggressive chemical media, high thermal and static stress. Constructors need materials specifically suitable for such requirements. Our plastics have been in use in the chemical industry for more than 50 years. They are particularly chemicals-resilient, heat-resilient and easy to process. Around the world, they help constructors build low-maintenance tanks and facilities with a high process safety.

Mechanical & plant engineering: plastics for efficient processes
Even after heavy loads and countless operating hours, plant and machinery must continue to operate reliably. That means designers need a whole variety of materials depending on the application. These must, for instance, have good friction properties, high temperature resistance or thermal insulation. We offer plastics that are developed specifically for these requirements. We would be happy to advise you on the selection of suitable materials for your particular application.

Drinking & Waste Water Technology
Fresh, clean water is a precious commodity. The efficient sourcing and treatment of water is vital for our quality of life. Sodium hypochlorite, chlorine and ozone are among the aggressive chemicals used for treatment. Installations must be able to withstand these influences for the long term. We offer plastics that are designed specifically for these requirements: they have a high resistance to chemicals, have the necessary purity for contact with drinking water and are easy to process. You can use them to design safe and long-lasting installations. We offer a complete system comprising of sheets, U and hollow profiles, welding rods and the tank construction programme.
Your advantages
High operational reliability thanks to very high resistance to chemicals
Long service life because of high resistance to wear and tear
Lightweight for easy installation
Suitable for outdoor use thanks to high UV resistanceVery easy to weld and process

What is the difference between HDPE Marine Board and ordinary HDPE sheet?
Skyguards HDPE Marine Board adopts special UV‑stabilized formula. Compared with standard HDPE sheets, it delivers better salt‑spray, acid‑alkali and weather‑resistant performance, suitable for long‑term service in coastal and seawater environments, and avoids aging and brittleness caused by sunlight exposure. -
Can HDPE Marine Board be used under long‑term saltwater immersion?
Yes. It features ultra‑low water‑absorption performance (<0.01%). It will not absorb water, swell, rot or delaminate under continuous saltwater immersion. It resists seawater corrosion and salt‑spray erosion very well.
-
Is Skyguards HDPE Marine Board UV‑resistant for outdoor marine scenarios?
UV stabilizers are added into the material formula, not only a surface coating. Even after cutting, drilling or machining, it still maintains stable anti‑UV capacity, resisting fading and brittleness under long‑term sun exposure.
-
Can HDPE Marine Board be machined with common tools?
Absolutely. It can be cut, drilled, routed, sawed and thermo‑formed by regular woodworking or plastic‑processing tools. Custom sizes, thicknesses and cut‑to‑size processing services are available.
-
What are the main application scenarios for HDPE Marine Board?
Widely used for boat components, yacht interior parts, dock fender panels, pier facilities, coastal engineering, aquaculture equipment and other marine‑related projects. It is an ideal replacement for marine plywood and metal plates.
-
Does HDPE Marine Board have thermal expansion and contraction?
Like most polymer materials, it has a certain coefficient of thermal expansion. We suggest reserving proper installation gaps according to local temperature variation to prevent deformation. We can provide thermal expansion parameter for your design reference.
Also our HDPE marine board have a better properties in thermal expansion and contraction since we have add the important addictives. -
What about its service life in marine outdoor environment?
Under correct installation, Skyguards HDPE Marine Board can achieve long service life in coastal open‑air conditions, with low maintenance requirement; no painting or anti‑corrosion coating is needed in daily use.
-
Can HDPE Marine Board be welded?
Yes, Skyguards HDPE Marine Board can be completely welded with HDPE welding rods. We provide supporting matching welding rods. Proper thermal‑welding operation ensures reliable joint strength for marine‑environment installations.
-
Can HDPE Marine board be made with matte finish?
Yes. Our HDPE marine board is available in smooth finish, matte finish, solid‑color and dual‑color options.
