Quality Excellence

Quality Standards & Certifications

To make sure our quality is consistent we measure all our foam production according to ASTM D3574. We are able to adapt to the quality standard which our customers use as the state-of-the art laboratory is well equipped to measure foam quality.

Each production batch will be tested at 7 different quality parameters. Every customer question can then be adequately answered. Each process is well described and detailed in such a manner that we can use it to train our teams.

We have entered into the certification process for ISO 9001:2020 as well as for some specific standards which are being required by the customer, e.g. Oeko-Tex Standard 100 and CA 117.

To ensure an excellent quality product, it is important to focus on continuous improvement and training; when we get a request from a customer to make foam, the first thing we do is engage with the customer to understand the function of the foam in their manufacturing process and end-products. It enables us to focus on the right physical properties of the PU foam. We learn from their manufacturing process to transfer the right quality parameters into the foam development process.

In order to ensure the consistent quality of our polyurethane foam, we measure each and every lab sample we make as well as every batch we produce. We document these test results in a certificate of analysis (COA) which can be provided upon request.

The main physical properties that we are testing on are

  • • Density
  • • Hardness at 3 different positions
  • • Tensile strength
  • • Elongation at break
  • • Resilience or ball rebound
  • • Recovery time
  • • Air permeability
  • • Compression set
Density
Density

Basically the amount of kg per cubic meter (kg/cbm). The higher the density the more heave the foam of the same volume

Hardness
Hardness

The reverse force feeling of the foam upon putting pressure on it. Hardness is measured at 25%, 40% and 60% indentation, therefore also called CLD, compression load deflection

Tensile strength
Tensile strength

The maximum load that a material can support without fracture when being stretched, divided by the original cross-sectional area of the material. It expresses the strength and durability of the foam.

Elongation at break
Elongation at break

Elongation at break, also known as fracture strain, is the ratio between changed length and initial length after breakage of the test specimen. It expresses the capability of foam to resist changes of shape without crack formation.

Resilience
Resilience

Resilience is the ability for foam to spring back into its original shape after being compressed. Resilience indicates the elasticity or “springiness” of foam by how quickly it reshapes. Memory foam typically has zero resilience.

Recovery time
Recovery time

The amount of time it takes before the memory foam has returned after compressing at a set time and force (N). A slow foam takes longer to recover than a fast foam.

Air permeability
Air permeability

The airflow through the foam at a set volume and speed indicates the openness/closeness of a foam. Air permeability has direct impact on other characteristics, e.q. resilience.
