Polyurethane Foam Adhesive: Toxicity and Skin Contact

Polyurethane foam adhesive is a versatile product used in both industrial and household applications.  Since it's often used around people and in everyday items, strict quality standards are enforced.

How it Works:

This adhesive is a combination of aerosols and polyurethane foam. When dispensed, it expands to a sponge-like solid, with a volume 1 to 20 times its original size.  The final product's hardness, density, and strength can be tailored for various uses.

Common Applications:

- Industrial: Home appliances, furniture manufacturing, toy modeling, building insulation.

- Household: Sofa cushions, backrests, car seats, mattresses, bra paddings, clothing shoulder pads, and more.

Safety Considerations:

1. High-Quality Adhesives: When properly cured, qualified polyurethane foam adhesive is considered non-toxic and safe for direct skin contact. It shouldn't cause irritation or allergic reactions.

2. Low-Quality Adhesives: Low-quality options, however, can trigger allergic reactions and potentially release harmful substances during prolonged contact.  Therefore, the safety of the adhesive depends on its quality.

Choosing Wisely:

Select suppliers whose products meet established testing standards.

Consider reputable companies like Cosmoll, which specializes in foam adhesive research and offers comprehensive solutions for various applications. Their adhesives are used in demanding industries like automotive, electronics, medical, aerospace, and marine.

Remember:

Since polyurethane foam adhesive is present in many everyday items, choosing a high-quality product is crucial.  Low-quality options can not only result in poor performance but may also pose health risks due to potential harmful substances.
