Polymer Definition

Polymer has a scientific meaning regarding how molecules are bound in a chemical compound. It also is used to describe a wide range of products in the plastics industry rather than a single product. “Polymer” is as broad as the word “Metal”. Identifying an item simply as “polymer” is vague and misleading. It is like describing zinc washers and gold engagement rings all as “metal rings”. Just saying something is a polymer doesn’t mean it is appropriate for an outdoor kitchen.

Some companies use “polymer” or “marine grade polymer” to mislead consumers. They build an inferior PVC cabinet that does not perform like Werever’s HDPE cabinets. Vague marketing words hide this very important difference.

Polymer Examples

Polymer can have completely opposite properties. It can be either brittle or malleable. It can be elastic or inelastic. It can be cheap or expensive. It depends how the chemical compound is engineered. To illustrate how vague this term is, consider the fact that these items are all “Polymer”.

Marine Grade Polymer

You may see the term “Marine Grade Polymer”. Unfortunately, this is used by some companies as a misleading marketing phrase. It implies you are getting the best-of-the-best material, or even the same material another company uses, but the term actually doesn’t mean a thing!

Werever does use the words “marine grade” in literature because our material has actually been used on boats, in direct sunlight, for decades. This is not true of other outdoor cabinets.

Werever’s HDPE Cabinetry

Werever builds cabinetry with UV-stabilized High Density Polyethylene (HDPE). It can’t be painted. It resists stains. It won’t fade. It is maintenance-free. It has been engineered with the ideal ratio of impact-absorbing forgiveness while maintaining optimal structural integrity. It outperforms every other material in the outdoor cabinet industry, and yes, it is a “polymer”.


Our cabinets are not PVC. PVC is a cheaper raw material than HDPE, especially when it is air-injected. It does not meet the performance of HDPE. It is weaker. It must be painted to protect it from the sun. It is more brittle. It can “chalk” and warp. It simply does not have the longevity of HDPE. PVC is a polymer too, but it is an inferior building product with regard to performance for outdoor cabinetry.

Cost Difference

A cabinet made from PVC should have a lower initial purchase price than one made from HDPE. PVC cabinets will only be cheaper in the beginning. They require maintenance, painting to protect them from the sun and other outdoor elements. PVC cabinets can’t handle extreme temperatures so they’re not suitable for all climates. You will have to re-paint, repair, and eventually replace a PVC cabinet. That’s why their warranty is substantially shorter than our lifetime warranty. They cost less and perform accordingly.

"Polymer" doesn't mean it's "HDPE!"
