Custom Fabrications

FAQ

Questions we hear most often about custom fabrication

Q.

What material is best for the custom fabrication of a lab console or workstation?

A.

Polypropylene is preferable for most uses. This resilient, high-strength material is the lightest in weight of any thermoplastic. It resists strong acids, alkalis and oxidizers and has excellent thermal insulating properties. It can be welded and thermoformed, has a high strength-to-weight ratio and resists cracking. Custom fabrications that use polypro are also economical, compared to other engineered plastics.

Q.

What materials are incompatible with polypropylene?

A.

Polypro works well with a broad spectrum of chemicals and work conditions. Exceptions include applications involving aromatics, aliphatic solvents and chlorinated solvents.

Q.

Can a polypropylene fabrication be used outdoors?

A.

UV-stabilized polypropylene can be used outdoors.

Q.

How does polypropylene compare to polyethylene?

A.

A polypropylene fabrication has lower impact strength, but superior working temperature range and higher tensile strength.

Q.

Is polypropylene suitable for a clinical environment?

A.

Polypropylene is ideal for clinical and lab settings because it is mostly chemically non-reactive, resistant to high temperatures, and tolerant of sterilization.

Q.

Is polypropylene suitable for FDA/USDA applications?

A.

Custom fabrications of homopolymer polypropylene are FDA/ USDA approved.

Q.

Stainless steel custom fabrications are often recommended for food processing applications. Is a polypropylene fabrication a better option?

A.

Custom fabrications for food, pharma and other sanitary applications can be plastic, or stainless steel. The deciding factors are usually weight – polypropylene is substantially lighter – and cost. A polypropylene fabrication is lower in cost.

Q.

What material is recommended for custom fabrications for a chem plant?

A.

Iron contamination precludes carbon steel, so options include stainless or engineered plastics. Plastic is generally preferable, due to lower cost and weight, unless there are highly aggressive acids, or temperatures over 400°F.

Q.

We’re considering several custom fabrications for our manufacturing plant. Will a polypropylene fabrication withstand an occasional encounter with a forklift or hoist?

A.

A polypropylene fabrication is resilient, with a high tensile strength. Polypropylene can be easily repaired if damaged by a forklift, or other device.
