Largest Custom EVA Foam Manufacturer in China | Sansd — factory-direct EVA/PE closed-cell foam. If you want the short story: we stand behind materials and workmanship; we don’t insure misuse or bad installs. Now the longer, more useful version—practical, plain English, with real-world scenes.

You need clarity, not legal fog. Our baseline covers materials and workmanship under normal use. That means the EVA/PE foam you purchase from SANSD should match the spec you ordered—density, thickness, Shore C hardness, color, and lamination quality. If a genuine defect shows up, we’ll repair or replace the goods as the remedy. That’s the core.
What it doesn’t cover: incorrect installation (bad surface prep, wrong solvent, poor rolling pressure), misuse (off-label chemicals, crazy heat-gun exposure), normal wear, colour fade from harsh abuse, cuts/tears from tools, or damage from third-party parts. We also can’t be liable for labor, downtime, or indirect loss. That’s standard industry practice, said plainly.

Boat folks know the drill: salt, sun, foot traffic, fish blood—real life is messy. Our Foam Boat Flooring uses closed-cell EVA with marine-grade texture and 3M PSA options for stick-and-stay. Warranty looks at delamination, excessive material breakdown, and abnormal color shift under proper install.
Key reality checks:
Want to discuss a fleet retrofit? Swing by Foam Boat Flooring and ask for a sample set.
Compression set, tear resistance, skin contact—your clinic cares about that. For Orthopedic Foam, our claim review focuses on premature compression set, laminate bond failure, or out-of-tolerance thickness. Hygiene and heavy use naturally shorten life; daily load on insoles is no joke.
Heads-up:
You buy EVA Foam Sheet or EVA Foam Roll because you want consistent batch-to-batch behavior. We monitor CPK, thickness, and color tolerance, and we offer Pantone matching and multilayer lamination. Warranty covers defects in the delivered material—like wrong hardness, delam between layers, unusual porosity, or out-of-spec thickness.
Not covered: die-cutting mistakes, dull blades causing ragged edges, or drop-tests done way outside spec. For sports mats, normal denting over time from point loads is wear, not a defect.
Cabin heat, oil splash, heel scuff—tough conditions. Our Car Mat Material and NVH pads are supported by closed-cell structures that resist water uptake. Claims review looks at bond failures, excessive compression set, and spec drift from the PO. OEM glue, heat, and carpet backing vary, so assembly errors sit outside warranty. We’ll help you triage root cause—adhesive peel vs. foam spec—so you don’t chase ghosts.

Drainage, rebound, UV—these layers quietly do the hard work. For turf pads, warranty focuses on material integrity and laminate stability under normal exposure. Edge fray from wrong cutter or ponding due to site drainage isn’t a material defect. Need a sample pack? See Artificial Turf Padding on our site.
Cosplayers bend, carve, heat, seal, paint—honestly, they push foam further than industrial folks. We love it. Our warranty on Cosplay Foam is simple: if the slab we ship is off-spec (hardness, thickness, voids) or laminate comes apart under normal handling, we’ll replace it. Burn marks from a heat gun set to “dragon” or paint-solvent attacks? That’s on the process, not the base foam.

You buy foam to build, not to argue. So we engineer defects out early: Pantone color match, Shore C hardness windows, 3M PSA, waterjet/CNC, lamination with clean bond lines, and tight tolerances (think ±). We watch batch-to-batch CPK so the 1000th sheet feels like the 1st. Need custom density, texture, bevels, or emboss? That’s daily work here. MOQ? Let’s talk volume so you hit a clean cost curve—no exact numbers here, but we keep it fair.
If you’re building decks, insoles, or car mats at scale, you care about lead time, repeatability, COA, and RoHS/REACH comfort. We do those. And yes, we’ll cut samples: Request a sample at Sansd.
It’s not fancy, but it works—and it protects both sides.
