{"product_id":"pp-polypropylene","title":"PP Polypropylene","description":"\u003cp style=\"text-align: justify;\"\u003eWinkle PP is a polypropylene filament made in Spain. This semi-crystalline thermoplastic combines low density, flexibility and mechanical strength. It is hydrophobic, resists chemicals and fatigue, and allows elongation of up to 200 % before break.\u003cbr\u003e\u003cbr\u003eIt comes in 1.75 mm diameter on a 700 g spool, in Natural or Black, for hinges, clips, containers, laboratory parts and components subject to repeated torsion.\u003c\/p\u003e\n\u003ch2\u003ePrinting conditions\u003c\/h2\u003e\n\u003cp style=\"text-align: justify;\"\u003eWinkle recommends a 0.4 mm nozzle, an extrusion temperature of 220 to 250 °C and a speed of 30 mm\/s, with the first layer at 25 mm\/s. Printing takes place in a closed enclosure, on a heated bed, with an adhesive to improve polypropylene grip. The low electrical conductivity of the material suits insulating parts.\u003c\/p\u003e\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctr\u003e\u003cth\u003eMaterial\u003c\/th\u003e\u003ctd\u003ePolypropylene (PP)\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eDiameter\u003c\/th\u003e\u003ctd\u003e1.75 mm\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eNet weight\u003c\/th\u003e\u003ctd\u003e700 g\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eExtrusion temperature\u003c\/th\u003e\u003ctd\u003e220 to 250 °C\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003ePrint speed\u003c\/th\u003e\u003ctd\u003e30 mm\/s\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eEnclosure\u003c\/th\u003e\u003ctd\u003eClosed\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eRecommended nozzle\u003c\/th\u003e\u003ctd\u003e0.4 mm\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eDensity\u003c\/th\u003e\u003ctd\u003e0.89 g\/cm³\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eMelt flow index\u003c\/th\u003e\u003ctd\u003e8 g\/10 min\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eCharpy notched impact (23 °C)\u003c\/th\u003e\u003ctd\u003e30 kJ\/m²\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eElongation at break\u003c\/th\u003e\u003ctd\u003eUp to 200 %\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003cth\u003eManufacturing\u003c\/th\u003e\u003ctd\u003eSpain\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch2\u003eCompatibility\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eFDM\/FFF 3D printers accepting 1.75 mm filament\u003c\/li\u003e\n\u003cli\u003eClosed enclosure and heated bed\u003c\/li\u003e\n\u003cli\u003eBed adhesive recommended\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Winkle","offers":[{"title":"0.7 kg \/ Naturel \/ 1.75 mm","offer_id":59057179165016,"sku":"POL00700175NATNATWNK","price":19.99,"currency_code":"EUR","in_stock":true},{"title":"0.7 kg \/ Noir \/ 1.75 mm","offer_id":59057179197784,"sku":"POL00700175NEGNEGWNK","price":19.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0938\/8979\/0296\/files\/filamento-pp-polipropileno-winkle.jpg?v=1793969533","url":"https:\/\/3dprint.shop\/en\/products\/pp-polypropylene","provider":"3Dprint.shop","version":"1.0","type":"link"}
