Foam Padding Materials: A Buyer's Overview

Foam padding covers a wide range of materials. Buyers comparing options are usually trying to match a density, a feel, and a supply route to a specific end product: furniture cushions, mattress cores, automotive parts, shoe components, carpet underlay, or packaging. This overview maps the main categories Fungbillion supplies: rebonded PU foam, graded PU foam scrap, memory visco scrap, and Hi-Poly shoe foam.

Start With the End Use, Not the Material Name

Buyers often begin a foam padding search by asking for a density or a grade. That works when you already know the material. If you are comparing categories, start with the application instead. The same recycled PU feedstock can become a furniture cushion or a mattress core, but the required density, skin content, and cutting format change with the job.

• Furniture padding: rebonded PU foam in the mid to high density range is the common choice for seat cushions, backs, and armrests. See furniture applications.
• Mattresses: rebonded PU foam is used for domestic mattress and farming mattress cores. See mattress applications.
• Automotive: rebonded PU foam is designed for modular autoparts.
• Shoe components: Hi-Poly shoe foam scrap at 50-60 density is a dedicated input for shoe material production. See shoe material applications.
• Packaging: shredded foam can be cut or packed for protective use.

Once the end use is clear, the material shortlist usually narrows to two or three options.

Rebonded PU Foam: The Core Padding Material

Rebonded PU foam is the central product in this category. It is made with recycled PU foam and is 100% recyclable. Density ranges from 50kg/m3 to 300kg/m3, which gives buyers a wide band to match firmness and load-bearing needs. Shape cutting is supported, so blocks can be supplied in the geometry your line needs.

The listed intended uses are: replacement of virgin foam, furniture padding, farming mattress, domestic mattress, and modular autoparts.

Best for: furniture seating and backs, mattress cores, automotive modular parts, and any application where a denser, recycled-content foam can replace virgin foam.

Not the first choice for: very light, soft comfort layers. For those, look at shredded foam or other low-density options.

Graded PU Foam Scrap: AA, A, and B

Foam scrap is the feedstock side of the business. Grades are defined mainly by skin content and density, which affect how the scrap performs in a rebonding line or as a direct filler.

• Grade AA: around 5% skin, or 0-skin versions. Density 20-30kg/m3. The official AA line is: “quality is super good and price is also expensive”.
• Grade A: available in 5% skin and 15% skin versions. A middle option between AA and B.
• Grade B: around 15% skin.

Colors are black, white, or mixed. Color choice matters if the finished rebonded block will be visible or if you are matching a customer specification.

Memory Visco, Shredded Foam, PU Binder, and Other Inputs

Beyond standard scrap, several specialized materials cover filling, bonding, and niche applications.

• Memory visco (memory foam) scrap.
• Shredded foam: loose foam chips for filling, packaging, and cushion blends. Best where a free-flowing material is easier to handle than blocks.
• PU binder: the binding component for rebonded foam production and other foam-bonding processes. Best for processors who mix their own feedstock.
• 10mm thick foam carpet underlay.
• Dali skin foam: a specific scrap type for buyers who know the term.
• Hi-Poly shoe foam scrap (50-60 density): a dedicated input for shoe material production.
• Crushed fabric bra foam scrap: a specialized scrap stream.
• Old used foam: reclaimed foam for processes that accept post-use material.

Best for: match the input to your process. Shredded foam for filling, PU binder for in-house rebonding, Hi-Poly for shoe components.

Matching Material to Application

• Furniture padding: rebonded PU foam, 50-300kg/m3, shape cut. Choose density by seat firmness and expected load. Grade AA or A scrap if you rebond in-house.
• Mattress: rebonded PU foam for cores; farming mattress and domestic mattress are both listed uses.
• Automotive: rebonded PU foam designed for modular autoparts.
• Shoe material: Hi-Poly shoe foam scrap at 50-60 density.
• Carpet: 10mm thick foam carpet underlay.
• Packaging: shredded foam.

If two materials both look possible, compare skin content, color, density, and format against your line. Those four variables usually decide the choice.

Supply, Packaging, and Shipping

Fungbillion is a manufacturer and trading company based in Guangdong, China, with an Alibaba-listed supply ability of 5000 Ton/Tons per Month. Ports are Shenzhen or Guangzhou.

For scrap bales and compressed loads, the listed density range is 15-30kg/m3. Bales run 200-300kg. A 40ft container loads 18000-22000kg. One 40HQ loads 20-22 tons of AA-grade compression bales.

Payment terms accepted: T/T, L/C, D/P D/A, MoneyGram, Credit Card, Western Union, and Cash. Main markets are Mid East, South America, Southeast Asia, Africa, and the Domestic Market.

Best for: buyers who want to discuss rebonded foam and scrap feedstock together, plus payment terms and container planning based on bale weight.

Platform Badges

The Alibaba shop shows: “Onsite Check”, “13 YRS”, “Response Time ≤9h”, “on-time delivery ≥100%”. These are Alibaba platform badges, not product specifications or service commitments.

A Simple Selection Path

When buyers are unsure where to start, this order works: first name the end use (furniture padding, mattress, carpet underlay, packaging, shoe material, or feedstock for your own rebond line). Then decide whether you need finished rebonded foam or raw scrap — rebonded foam if you want a ready-to-cut block in the 50-300 kg/m3 range, scrap if you run your own shredding and bonding. Then narrow the scrap grade: Grade AA (around 5% skin or 0-skin, 20-30 kg/m3) where appearance and consistency matter most, Grade A (5% or 15% skin) for general production, Grade B (around 15% skin) where cost matters more than looks. Then fix color (black, white, or mixed), form, and volume. Each answer removes a wrong option, and what is left is a specification you can send to any supplier — including us. The foam scrap sourcing guide walks through the same path as a checklist.

What to Tell Us When You Inquire

To get a useful reply, include your end use, required density or density range, skin content preference, color, block or cut shape, bale size, target container load, destination port, and payment term. If you are comparing rebonded PU foam against scrap or visco, say so and we can map the options.
