Spigen Universal Waterproof Phone Case Waterproof
No coating described, and no PFAS statement from the brand.
The product information we reviewed describes tPU or silicone, with no water-repellent coating named. Water resistance on products like this usually comes from the material and its seals rather than a surface treatment. The brand has published no PFAS statement for it.

What Spigen Universal Case Waterproof is made of, ingredients and materials
Spigen's universal waterproof case is constructed from TPU (thermoplastic polyurethane) or silicone elastomer, both of which are non-reactive, non-leaching polymers designed for direct contact with electronics and skin. TPU and silicone do not contain BPA, BPS, or phthalates in their base formulations, and neither material is prone to significant leaching under normal phone-case use conditions (no heating, no prolonged chemical exposure). The case relies on physical seals and material density for waterproofing rather than applied coatings, eliminating risks from Teflon-type coating, waterproof resins, or flame-retardant treatments. These materials are widely used in medical-grade applications, signaling good chemical stability.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Seal material and gasket contamination
Silicone or rubber gaskets used in seals may occasionally contain minor residual silicone oils or release agents, but these are food-contact approved in other applications and exposure levels from phone cases present lower concern.
Bacterial or mold growth inside sealed case
If the case is sealed with moisture trapped inside, mold or bacterial growth can occur over time, particularly in warm climates. This is a usage issue, not a product chemistry issue, but periodic drying and ventilation are essential.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
BPA & bisphenols
TPU and silicone do not contain BPA or phthalates in their standard formulations. No public reports of leaching from Spigen cases of this type.
Source, FDA ↗Coating degradation and chemical off-gassing
This design uses no applied water-resistance coating; waterproofing is inherent to the material and seals. No off-gassing or coating-peel hazards are reported.
Heavy metals
No recalls or public reports of lead, cadmium, or other heavy metals in Spigen phone case pigments. Color additives in consumer electronics cases are typically low-concern azo dyes or inorganic oxides.

The brand's record and disclosure
Spigen has not published a formal PFAS statement or detailed material safety documentation for this product line, which is consistent with many consumer electronics accessory brands that treat material specs as proprietary. The brand has no documented recalls or safety controversies related to leaching, off-gassing, or coating hazards on their phone cases. Spigen is a privately held South Korean manufacturer with a reputation for affordable, functional protective cases rather than premium or chemical-intensive designs, reducing the likelihood of unnecessary additives or coatings.
How it compares in its category
Waterproof phone cases typically fall into two camps, sealed rigid plastic shells (often polycarbonate or ABS with coating-based water resistance) and soft elastomer designs like this one. This TPU/silicone case avoids the risk of coating degradation or peeling that affects some cheaper rigid alternatives. Compared to cases made from PVC or those with synthetic rubber that may contain undisclosed flame retardants or UV stabilizers, TPU and silicone represent lower concern options in the waterproof case market.
If you buy it
Inspect seals and gaskets before first use to ensure they are intact; a small amount of salt water or debris can compromise waterproofing. Avoid prolonged exposure to direct sunlight or heat above 60 degrees Celsius, as TPU and silicone can soften and lose seal integrity. Rinse the case periodically with fresh water if exposed to salt water or chlorine, and air-dry completely before sealing your phone inside. Replace the case if you notice visible cracks, seal loosening, or permanent deformation, as waterproofing will fail.
