Phthalate-free

Phthalates are plasticizers added to soften rigid plastics. They're a particular concern for children because they're easily transferred via mouthing behaviour and are linked to endocrine disruption and reproductive-development effects. CPSIA restricts the eight listed phthalates in children's toys to <0.1% by weight.

PopsyKosy uses no phthalate plasticizers — the EVA polymer chain is naturally flexible without them. Each batch is third-party tested below detection limits.

Why this term matters at PopsyKosy

This safety-adjacent terminology is part of the foundation we built PopsyKosy on. Every PopsyKosy mat is engineered to USP Class VI biocompatibility (the testing tier used for medical-device components polymer chemistry) plus OEKO-TEX Standard 100 Class I certification (the strictest textile-chemistry tier, originally written for infant skin contact). These two standards combined define the safety bar most playmat brands do not meet.

The mat is designed in Los Angeles, precision-manufactured in Taichung, Taiwan — not in China, not in mixed-ownership facilities. Each pattern is single-density-molded tile EVA (no tile seams to peel, no foam delamination, no adhesive layers to off-gas). The 0.5″ and 1″ thickness options both meet ASTM F1292 fall-protection thresholds. Independent COA documents are published in full on our Certifications page.
