What Limitless 5.0 Case is made of, ingredients and materials
The Limitless 5.0 Case uses a rigid polycarbonate shell paired with a silicone bumper. Polycarbonate is a durable, clear thermoplastic that resists impact and UV exposure without requiring surface coatings that degrade over time. Silicone is inert, non-leaching, and commonly used in consumer electronics for shock absorption. Neither material is known to off-gas volatile organic compounds (VOCs) or release harmful chemicals during normal handling or storage at room temperature.
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.
Polycarbonate degradation and brittleness over time
Polycarbonate shells can become brittle or discolored after extended UV exposure or thermal stress, potentially reducing impact protection. This is a durability concern rather than a chemical hazard, but it affects safety function.
What’s reassuring
BPA & bisphenols
Polycarbonate is a BPA-containing polymer by chemistry, but under normal case-use conditions (no heat, no liquid contact, no mouthing), leaching risk is negligible. Mous has not confirmed BPA-free material sourcing; direct contact with the shell during typical handling poses no established hazard.
Source, FDA ↗Silicone bumper composition and purity
Silicone is generally inert and does not leach plasticizers or phthalates. No public recalls or contamination reports exist for this product. Mous has not disclosed whether silicone meets food-grade or medical-grade standards, but for a protective case this is not a practical exposure concern.
Volatile organic compound (VOC) off-gassing
Polycarbonate and silicone do not typically off-gas VOCs during storage or use at room temperature. No odor complaints or indoor air quality concerns have been reported for this product category.
Heavy metals
No recalls, testing data, or credible reports of lead, cadmium, or other heavy metals in Mous cases exist. The brand has not disclosed colorant sourcing or third-party testing; standard polycarbonate and silicone formulations are not flagged for metal contamination risk.

The brand's record and disclosure
Mous has not publicly disclosed material certifications (such as RoHS, BPA-free, or phthalate-free statements) for the Limitless 5.0 Case. The brand's stance on PFAS is silent, meaning no public commitment or testing data is available; transparency on material sourcing and chemical composition remains limited. No recalls, safety complaints, or regulatory actions specific to this product model have been reported in public sources.
How it compares in its category
Phone and device cases in this durability tier typically use polycarbonate, TPU, or silicone; the Limitless 5.0's hybrid design (rigid shell plus flexible bumper) is standard practice. Polycarbonate cases are generally lower-concern than thin plastic or untested rubber formulations because the material is well-established and not prone to leaching under normal use. Silicone bumpers avoid phthalate risks that can occur in cheaper PVC-based cushioning.
If you buy it
Keep the case away from prolonged direct sunlight, high heat (over 50°C), and strong solvents, as polycarbonate can become brittle or discolor over time. Wash with mild soap and water if needed; silicone bumpers do not require special maintenance. Replace the case if cracks or chips develop in the polycarbonate shell, as structural integrity is compromised. No risk of leaching or off-gassing during typical indoor use.
