Material specifications
Material clarification
Our labels are manufactured using multi-layer engraving laminates, commonly referred to in the industry as “phenolic labels.” They are not made from true phenolic resin-based material. The terminology is widely used in electrical and industrial labeling to describe engraved plastic laminate labels.
If your project specifies a particular substrate or performance requirement, include it with your quote request so we can confirm the material before production.
Specify the actual engraving stock, dimensions, exposure, and attachment method when ordering. “Phenolic,” “lamacoid,” and “engraved plastic” are common trade terms, but they do not establish a manufacturer grade, continuous-use temperature, or outdoor service life.
True phenolic and modern engraving laminate
True phenolic is a thermoset resin-based laminate. Modern engraving laminates commonly use layered acrylic or other plastics with a colored surface over a contrasting core. They are different material families. If your drawing specifies true phenolic or a particular grade, send that requirement unchanged for review.
Custom Phenolic Labels uses modern engraving laminates for many identification orders. True phenolic or specialty material can be discussed when the project requires it; sourcing, color, dimensions, and lead time need confirmation before production.
Dimensions, thickness, and colors
Match the material to its environment
Indoor identification
For interior panels, equipment, and mechanical rooms, identify the actual mounting surface, operating temperature, cleaners, and handling conditions. An indoor application can still involve heat, moisture, or chemical exposure that requires a different stock or attachment.
Outdoor and UV-exposed labels
Request outdoor-rated stock and identify orientation, sunlight, moisture, temperature cycling, and expected maintenance conditions. An outdoor rating does not mean every color or finish has the same performance, and it is not an unlimited service-life guarantee.
High heat and chemical exposure
Provide the normal and peak temperature, exposure duration, chemical names and concentrations, and cleaning process. Check the selected manufacturer datasheet. A heat-deflection or softening test result must not be treated as a continuous-use temperature rating.
Reverse engraving can protect the engraved side of a plate in some applications, but it does not establish a higher temperature or chemical rating by itself. Specify both the substrate and any backing, paint fill, or adhesive used in the assembly.
Electrical and controlled-environment requirements
If dielectric performance, flame classification, ESD control, particle generation, or outgassing matters, provide the governing specification. These properties require material-specific documentation. A general description such as non-metallic or engraving laminate does not demonstrate that every requirement is met.
Mounting is part of the specification
Adhesive compatibility depends on the substrate, surface preparation, temperature, moisture, and loading. Mechanical mounting requires suitable hole placement, fasteners, and tightening. Choose both the plate material and attachment for the installation, and follow the applicable supplier instructions.
Documentation to request before approval
- Manufacturer and product series, color or item code, thickness, and ply configuration.
- Current technical datasheet and safety data sheet for the proposed material.
- Relevant outdoor, thermal, chemical, electrical, or flame-performance documentation for the actual grade.
- Adhesive or fastener specification and an approved dimensional drawing where needed.
Material selection alone does not establish compliance for the completed label. Required text, visibility, location, size, color, and mounting also matter. Confirm the adopted code edition and project requirements with the designer or authority having jurisdiction.
Frequently asked questions
What does lamicoid or lamacoid mean on a drawing?
These trade terms often describe layered engraving stock. Preserve the exact wording from the drawing and ask whether a specific manufacturer, grade, or material standard is required before selecting a substitute.
Can modern engraving laminate crack during installation?
Yes. Material thickness, hole spacing, bending, and fastener pressure affect the risk. Use the approved mounting details and avoid overtightening; impact resistance is not a guarantee against damage.
Are engraving stocks electrically non-conductive?
Many engraving plastics are used for electrical identification. When a project requires a dielectric or flame rating, verify the exact grade and its documentation instead of assuming compliance from the material name.
Can you supply true phenolic when a drawing requires it?
Send the specified grade, standard, dimensions, quantity, and deadline. The team can review sourcing and confirm availability before quoting. Do not substitute modern laminate without the responsible party’s approval.
Can I request a manufacturer datasheet or safety data sheet?
Yes. Identify the project requirements with your quote request so the proposed stock and relevant documentation can be reviewed before approval.
What temperature rating should I use?
Use the manufacturer’s applicable service rating for the selected stock and the actual exposure. Test values such as heat deflection and softening point are not interchangeable with a continuous operating temperature.
Does engraving guarantee that a label will never fade?
No. Engraving creates recessed character shapes, but the substrate, color layers, and attachment can still be affected by weather, chemicals, abrasion, or heat. Select the stock for the exposure and inspect labels during maintenance.
Manufacturer references
Rowmark LaserMax specifications identify the material and separate thermal test properties. The manufacturer resource library provides technical and safety documents. These are reference examples, not confirmation that a particular grade or color is allocated to your order. Request documentation for the stock named in your quote.
