Material
Synthetic rubber and polyurethane core with cover stock
Brand disclosure
Brand is silent on PFAS
Lab data
No public lab test
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.
Microplastic shedding during use
Normal wear and cover degradation over time may shed small polyurethane particles into grass or water hazards, particularly on scuffed balls. This is an environmental concern rather than a direct consumer health hazard, but worth noting if environmental impact is a consideration.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Volatile organic compound (VOC) off-gassing
Cured polyurethane and synthetic rubber do not emit detectable VOCs under normal outdoor temperatures or storage conditions. Off-gassing is not a documented concern for golf balls in any manufacturer data or independent testing.
Heavy metals
Polyurethane and synthetic rubber formulations do not require lead, cadmium, or antimony as additives. No recalls or test reports indicate heavy metal content in OnCore Mix or comparable golf ball products.
Source, FDA ↗Phthalate plasticizers leaching
Polyurethane covers and synthetic rubber cores are not formulated with phthalates as primary plasticizers; these materials maintain integrity without them. No documented cases of phthalate migration from golf balls into skin or groundwater.
Skin contact allergic reaction or sensitization
Polyurethane and synthetic rubber are widely used in gloves, athletic equipment, and footwear without elevated allergy reports. No documented hypersensitivity cases linked to golf ball materials or OnCore products specifically.
The full breakdown
What it's made of and why it matters
OnCore Mix balls use a synthetic rubber core wrapped in polyurethane cover stock, a standard construction across mid-to-premium golf balls. Polyurethane is thermosetting and chemically stable once cured; it does not leach plasticizers like phthalates under normal temperature and humidity conditions in golf play. The synthetic rubber core is similarly inert during use. Neither material is known to off-gas volatile organic compounds (VOCs) at room or outdoor temperatures typical of golf.
The brand's record and disclosure
OnCore Golf maintains minimal public disclosure on material sourcing or chemical safety testing. The brand has not published third-party certifications or safety statements regarding heavy metals, volatile compounds, or manufacturing controls. No recalls or safety incidents are on record for OnCore Mix products. Absence of disclosure does not indicate a problem, but reflects the low regulatory scrutiny applied to golf equipment compared to food contact or apparel categories.
How it compares in its category
Golf balls across brands (Titleist, Callaway, Bridgestone, etc.) use similar polyurethane cover and synthetic rubber or ionomer core materials with no differentiated safety profiles. OnCore Mix sits in the mid-tier performance segment and does not use exotic materials that would elevate or reduce chemical risk relative to competitors. The category as a whole has not been subject to consumer safety scrutiny comparable to cookware or textiles.
If you buy it
Store balls in cool, dry conditions to prevent any possible long-term UV degradation of the cover (this is cosmetic, not a safety issue). Do not expose to extreme heat (e.g., leaving in a hot car for extended periods) because polyurethane can soften, though this will not create toxic release under typical use. Replace balls when cover scuffing or cracking becomes visible, as this affects performance and may expose the core. No special handling or maintenance is required for safety.
