Wood Plastic Composites (WPC)

Building the future with wood plastic composites

Explore additives and impact modifiers to enhance wood polymer composites that can be more sustainable and durable than regular wood. The popularity of wood polymer composites keeps growing. A long list of building, construction, and even automotive applications can benefit from great long-term durability and appearance. Minimal maintenance, lightweight, and weather resistance - all with the potential for lower life cycle costs compared to traditional lumber. 

That’s why we’re excited to share a rich portfolio of wood plastic composite polymers that help deliver all that – plus the ability to develop innovative solutions with improved sustainability, processability, and performance.

A diverse portfolio of materials with attributes both in and outside wood plastic composites

AMPLIFY™ Si PE 1000

Find out what AMPLIFY™ Si PE 1000 technology brings to the table.

Enhanced sustainability with Dow WPC

Our silicone-enhanced polymer system (SEPS) – AMPLIFY™ Si PE 1000 Polymer System – allows even higher levels of recycled plastic and wood content while maintaining or improving Wood Plastic Composite performance.


WPCs made with AMPLIFY™ Si materials can help reduce energy costs and carbon footprints. As a result, they help support efforts toward a more circular economy.

FUSABOND™ Functional Polymers, AMPLIFY™ GR Functional Polymers, and SURLYN™ Ionomers also help extend the life of WPC boards, keeping them out of landfills longer.

Wood plastic innovation through collaboration

Developing wood polymer composites with Dow and our diverse portfolio puts a wealth of material science expertise at your fingertips. This gives you the flexibility to design innovative, differentiated WPC solutions that focus on specific application challenges.

Improved throughput, processability and appearance

The lower melt temperature of AMPLIFY™ Si PE 1000 helps reduce torque and thermal degradation during processing. This enables not only increased productivity with fewer rejects, but also better appearance/color.

Our FUSABOND™ and AMPLIFY™ GR Functional Polymers offer a range of excellent coupling agent options. For example, FUSABOND™ M603 Functional Polymer features exceptional bonding between wood fibers and the polymer matrix, with less susceptibility to lubricant interference.

In the cap layer, SURLYN™ Ionomers add excellent clarity and aesthetics for great appearance.

Excellent toughness, durability and service life

The low melt temperature of AMPLIFY™ Si products also helps improve tensile and flexural strength in finished WPCs.

FUSABOND™ coupling agents also support long-term durability, with an improved modulus of rupture (MOR) and modulus of elasticity (MOE), dimensional stability, fiber dispersion, impact and creep resistance.

Likewise, DOW™ High Density Polyethylene (HDPE) Resins, in virgin and/or recycled form, offer excellent strength and durability to WPC formulations. (Other virgin and/or recycled PE materials can also be used.)

And again, SURLYN™ Ionomers “cap it all off” with exceptional resistance to impact, scratches, stains, and ultraviolet (UV) light to help extend product life.

Increased moisture resistance

The absorption of moisture by wood fibers can lead to swelling, mold, and severe damage to WPCs.

Fortunately, FUSABOND™ M603 Functional Polymer is ready to help. The unique anhydride functionality of this random ethylene copolymer enables improved moisture resistance and strength when used at lower levels than traditional maleic anhydride grafted (MAH) coupling agents. At higher levels, it can provide even better performance, for dramatic reductions in water absorption.
