Phenolic vs. Stainless Steel vs. HDPE Bathroom Partitions


Factors to Consider When Choosing a Bathroom Partition

When evaluating bathroom partitions for public and commercial restrooms, keep the following seven factors in mind:

  • Durability / Water Resistance

  • Fire Classification

  • Cost

  • Longevity

  • Sustainability

  • Appearance

  • Regulations and Code Compliance

Taking care to identify bathroom partition materials that meet high standards of both function and design, you find three primary options rise to the top: HDPE plastic, phenolic panels, and stainless steel.

What is HDPE?

HDPE stands for high-density polyethylene. This material is made by applying intense heat to petroleum in a chemical process called cracking. The cracking process creates ethylene gas, whose gas molecules then group together to form polymers. The polymers in turn produce polyethylene in a sludgy state. After putting it through a number of molds, the sludgy polyethylene hardens into a strong plastic.

Usually, HDPE is used to create sturdy jugs that store liquids like bleach and laundry detergent. When used to create bathroom partition walls, the plastic is made thicker. HDPE’s high strength to density ratio means that the thicker the material, the stronger it is.

Why Use HDPE as a Bathroom Partition?

Antimicrobial

Solid plastic bathroom partitions stand out because of their antimicrobial properties. Mold and mildew will not grow on solid plastic, making it an ideal material for public restrooms and commercial bathroom partitions which are susceptible to mold and mildew growth.

Low Maintenance

Solid plastic bathroom partitions require minimal maintenance. In addition to mold and mildew resistance, HDPE remains free from rot, rust, oxidization, and delamination. Quickly remove dust and loose dirt with a damp cloth and a mild cleaning agent; and when a rare stain occurs, non-abrasive and industrial strength cleaning products can be used without concern. Because the solid plastic is not porous, water can easily rinse off any cleaning product without damaging the material. Another benefit of the nonporous material is that it does not absorb odor.

HDPE Plastic Bathroom Partitions: Pros and Cons

  • Resists mold and mildew

  • Resists stains and graffiti

  • Rust-proof

  • Does not de-laminate

  • Does not absorb odor

Cons

  • Expensive

  • Not fire retardant

What are Phenolic Panels?

Phenolic panels are also known as HPL panels (high-pressure laminates). High-pressure laminate panels begin as natural core material layers impregnated with thermosetting resins. These are cured under high pressure and heat to create highly resistant and versatile architectural panels. HPL panels provide maximum design freedom by offering high performance and abundant aesthetic options.

Specifically, Fundermax phenolic panel manufacturing begins with sustainable raw materials sourced from vendors certified according to Forest Stewardship Council standards (FSC) or PEFC™. Next, a proprietary phenolic resin is added to the kraft paper layers which are cured under high heat and pressure to create the panel core. The manufacturing process can be replicated to create a wide variety of panel decors and finishes.

Phenolic bathroom partitions have proven to be more durable than solid plastic.[1] The superior durability of HPL panels, even under harsh conditions, results in extraordinary longevity. The initial investment in phenolic resin panels is admittedly more expensive than other bathroom partition materials, but the higher price makes sense when considering the longevity of the product.

Like HDPE, phenolic panels are low maintenance, water-, moisture-, rot-, rust-, and odor-proof. HPL panels will not delaminate or peel, and they resist fading as well. HPL does not have the same antimicrobial properties as HDPE, but its durability includes chemical resistance that allows for virtually any cleaning product. High-traffic and vandalism-prone areas like public restrooms are no match for the graffiti-, scratch-, and wear-resistance of phenolic bathroom partition panels.

Why Use Phenolic Panels as a Bathroom Partition?

Flame Retardant

When safety matters, building owners choose phenolic bathroom partitions because they are flame retardant. Phenolic panels do not require additional layers of flame retardant substances or coatings.

Low Maintenance

As we mentioned above, maintaining high-pressure laminate bathroom partition panels is simple. Regular cleaning requires only warm water and mild soap, and the material’s durability can withstand more thorough cleanings when necessary. (It is not advisable, however, to use bleach-based or abrasive cleaners.)

Phenolic Bathroom Partition Panels: Pros and Cons

Pros

  • Durable and wear-resistant

  • Resists water and moisture

  • Resists stains and graffiti

  • Rust-proof

  • Does not de-laminate

  • Does not absorb odor

  • Fire retardant

  • Wide variety of décor options

Cons

  • Expensive 

What is Stainless Steel?

What are the properties of phenolic board? - ztelec

Phenolic sheet is known as the "king of thermal insulation materials", is a new generation of thermal insulation, fire prevention, sound insulation materials. Phenolic sheet material has the characteristics of light weight, fire prevention, non-flammable, smokeless, non-toxic, no water dropping and so on. And the application temperature range is wide. Phenolic board has been recognized by the construction department and the public security fire department as a safe, green and new energy-saving building material.

1) Phenolic plates were used in the insulation of missiles and rocket heads in the early stage.

2) Phenolic sheet material is widely used in high-rise buildings, transportation, ships, aviation, space technology and other fields.

3) Petrochemical and other pipeline insulation field use tube and shell products cut by phenolic insulation board widely.

4) Phenolic insulation board composite products are applied to large in-mold system in building insulation engineering, A class fire insulation system, building wall insulation decoration integration system, fire door interlayer, color steel sandwich panel room and other fields.

Phenolic board features and advantages:

The phenolic plate like black phenolic sheet has the characteristics of no shrinkage and no brittle crack at the low temperature of 96℃~+100℃. Phenolic foam has low thermal conductivity (less than 0.020 w/mk), good thermal insulation, water resistance and moisture penetration. It is a good heat preservation and energy saving material, but also an ideal heat preservation material for HVAC and refrigeration engineering. Because phenolic has benzene ring structure, the size is stable and the change rate is less than 1%. And it has stable chemical composition, corrosion and aging resistance, especially resistance to organic solution, strong acid and weak alkali corrosion. Freon is not used as foaming agent in the process of foaming, and this is in line with international environmental standards, the molecular structure contains hydrogen, oxygen, carbon elements. When decomposed at high temperature, the spilled gas is non-toxic and odorless, harmless to human body and the environment, and meets the national green environmental protection requirements. Therefore, phenolic super composite board is green heat preservation material with ideal fireproof, heat insulation, energy saving, beautiful appearance, and environmental protection.
