Complete XPE Foam Mat Manufacturing Process
At our child-safe production base, we engineer XPE foam crawling mats with medical-grade material standards. Equipped with dedicated XPE foaming lines for infant products, we implement ISO 10993 biocompatibility protocols throughout the process. Discover how food-grade polymers become protective play surfaces for toddlers:
Step 1: Automated XPE Foam Pellet Production
Our in-house engineered compounding system integrates twin-screw extrusion and supercritical CO₂ injection to directly manufacture cross-linkable XPE masterbatch pellets. The closed-loop process combines 95% virgin LDPE resin with 5% recycled post-industrial XPE scrap, foaming agents (azodicarbonamide-free formula), and peroxide cross-linking precursors under precisely controlled 135-145°C thermal conditions.
Step 2: Foaming & Sheet Formation
Using automated precision equipment, XPE pellets are fed into an extrusion system where they are melted, expanded with nitrogen gas, and cross-linked under controlled heat. The foam is rapidly cooled to stabilize its closed-cell structure, trimmed to exact thickness (10-30mm), and rolled into uniform sheets—ensuring EN71-3 compliance, zero toxic emissions, and consistent density for child-safe crawling mats.
Step 3: Protective Film Lamination
Our automated film-coating system applies food-grade PE/PET surfaces to XPE foam sheets using solvent-free hot-melt adhesives. The process ensures scratch-resistant, waterproof layers (0.1-0.3mm thickness) with anti-slip textures, meeting CPSIA and EN71-3 safety standards for child-friendly durability.
