MATERIAL SCIENCE
It’s The Science Behind Our Decking That Defies The Elements
DuxxBak® Composite Decking
DuxxBak® Composite Decking is committed to using science-proven processes, both in our manufacturing and our quality control programs, to assure a predictable, consistent product for all of our end users.
Our material formulation is proven. Some of our decks have been exposed to the elements for nearly 20 years, in many different climates, with no ill effects. While other manufacturers are reformulating their products to address issues with weathering, fading, mold growth or heat retention, our science-based approach has delivered year after year of happy clients.
HOW IT’S MADE
SCIENCE & FORMULATION
Our material science combines:
High density polyethylene (HDPE)
Rice Hulls
Biodac
Colorant
Antioxidant, Antifungal, Other
Click through the tabs below to learn more about each ingredient.
High Density Polyethylene (HDPE)
Virgin material – free of contaminants
Highly resistant to chemical attack
Density (0.960) contributes to density of decking
Density contributes to resistance from internal attack
Readily available in the required quality specs
Strong
Chemically resistant
Non-toxic
More consistent product
Better control of properties
Less variation
Clean (No commingling or dirt)
Rice Hulls:
High silica content (sand or glass like)
Natural protectant qualities
Provides strength and stiffness attributes
Rapidly renewable resource – Environmentally friendly
Biodac:
Mineral reclaim from paper industry
Environmentally sustainable
Very high density (1.32) contributes to density of our product
Contains calcium carbonate and clay – Inert materials that contribute to stable product
Tannins and lignins stripped from by-product to help resist staining and fading
Colorant:
Iron oxide base provides a stable color quality
Helps resist fade
We only use colorant from renowned suppliers
Added during board extrusion process to provide production control
Anti-oxidant:
Serves a dual purpose in manufacture and board service life
Provides resistance to thermal destruction of plastic in the manufacturing process
Acts like an ultra-violet (UV) inhibitor to resist attack and breakage of the plastic chain
Anti-fungal:
Helps prevent the growth of fungal material within the decking
Lubricant:
Serves a dual purpose in manufacture and board service
Mates with iron oxide based colorants to migrate in and out to create surface finish
Materials:
All incoming raw materials are submitted to QC testing and validation.
If it does not pass, it is rejected and not used.
There is no “good enough” for Green Bay Decking products.
The quality of the materials directly affects the quality of the products.
