What Are the Raw Materials of Sublimation Blanks Products?

 Sublimation blanks are specially designed products that allow sublimation ink to bond permanently. Their raw materials determine how well they accept sublimation prints and how long the designs last.

Polyester Fabrics
Polyester is the key material because sublimation ink only bonds with polyester fibers when exposed to heat and pressure. Common products include T-shirts, hoodies, jerseys, socks, tote bags, and pillowcases. A polyester content of 65% or higher ensures vibrant, long-lasting results. Cotton-only fabrics are not suitable unless pre-treated with a special sublimation coating.

Polyester-Coated Ceramics
Ceramic mugs, plates, and tiles are naturally porous, so they must be coated with a polyester layer to hold sublimation ink. Common products include coffee mugs, travel mugs, tiles, and coasters.

Polyester-Coated Metals
Metals like aluminum and stainless steel require a sublimation-friendly polyester surface. Common products include photo panels, keychains, license plates, and ornaments. These blanks are durable, lightweight, and resistant to scratches.

Polyester-Coated Glass and Acrylic
Glass and acrylic sublimation blanks are coated to allow clear, vivid designs. Common products include photo frames, clocks, awards, phone stands, and signage.

Hardboard and MDF (Medium-Density Fiberboard) with Polyester Coating
These are widely used for sublimation photo panels, coasters, puzzles, and signage. They are lightweight, affordable, and deliver excellent color vibrancy.

Specialty Items with Polyester Layers
Some specialty items such as faux leather (for wallets, keychains, notebooks) and sublimation-ready plastics (for phone cases, water bottles, tags) are also made with polyester coatings to allow sublimation.

Addressing Common Concerns

Why can't sublimation work on cotton or uncoated surfaces?
Sublimation ink bonds only with polyester molecules. Without polyester fibers or coating, the ink won’t transfer permanently.

Are all coatings the same?
No. High-quality coatings result in brighter, longer-lasting prints, while poor coatings may fade, peel, or scratch easily.

Do raw materials affect durability?
Yes. Fabrics with higher polyester content and properly coated surfaces ensure designs remain vibrant even after repeated washing or use.
