Inflatable dropstitch material lets us build inflatables with flat surfaces that can be inflated to rock-hard rigidity. You get hard-shell performance along with the easy transportation and storage of an inflatable. What makes this possible? Tens of thousands of fine threads. The process starts by joining two pieces of polyester base fabric with thousands of fine polyester thread lengths. This base material is made in strips from 1 to 2meters in width. Next, an air-tight material is applied to the outer surfaces of both sides of the material. The sidewall material is made of polyester base fabric that is coated on both sides. Polyester thread is used throughout because it is strong, durable and has very little stretch. The actual assembly process involves labor-intensive gluing of the sidewall material to the top and bottom pieces of the drop-stitch material. Then a wide seam tape is glued over each lap seam for a bomber, air-tight final product. What you have now is a super strong construction that can be inflated to pressures up to 20 pounds per square inch (psi).

There is increasing concerns from Europe and US regarding Phthalates. Phthalates refers to Phthalate Esters / PAEs, which are common addictive to soften plastics especially PVC in past 40 years and 80% of Phthalates are used in plastic products. It exists in others include inks, adhesives, sealant agents, paints, film coatings, glass fibers, leather, rainwear, footwear, dyestuff, perfume, softener, polish remover, lubricant, cosmetics and isolation for cables. Phthalates has toxic for reproduction. Based on the application and customer’s safety concerns, there are tests based on different Phthalates. The common testing are 3P, 6P, 7P, 15P and 16P. Our product has passed reach standard, and for higher requirement, we can make 6P/16P.

Fusion construction (Pre-laminated dropstitch ) is a sweet spot for balance of weight, rigidity, and cost-effectiveness. The top and bottom sheets of the drop stitch have two layers of fabric that are permanently bonded to each other and a layer of PVC coating on the outside of this double-ply fabric. The resulting board is significantly more rigid and puncture-resistant than a single layer board. The added rigidity of the material allows boards to be made in 5” thickness without having to resort to excessive board thickness for the sake of rigidity. Technically, fusion material also has two fabric layers, but it should be noted that there is a distinct difference between fused material boards (two layers of fabric fused at the raw material stage, with a single coating applied to the outside surfaces) and actual dual layer construction boards, in which a second distinct layer of PVC coated fabric is laminated to the board.
READY MADE PRODUCTS:
Since 2015, we setup a facility with experienced team to make dropstitch OEM products like SUPs , Air mattess, Floating Platforms and all kinds of custom built inflatable products. During these years we have trained a group of professional designers and experienced workers. The whole process from material manufactuering, material cutiing, silk printing , bag sewing and testing are all finished by ourself. So quality is 100% under control. And we can also help a lot customers to upgarde their products with latest technology and material.
