Full Description

Nylon 12 (polyamide 12, CAS 24937-81-3) is a semicrystalline aliphatic polyamide engineering thermoplastic. Established uses include flexible tubing and fluid lines, polyamide powder coatings, selective-laser-sintering powder for additive manufacturing, and molded engineering components.

Frequently Asked Questions

What is nylon-12 used for?

Nylon 12 is an engineering thermoplastic used for flexible fuel, brake, and pneumatic tubing and lines, polyamide powder coatings, PA12 powder for selective-laser-sintering 3D printing, and molded engineering parts requiring chemical and impact resistance.

Is nylon-12 a plastic?

Yes. Nylon 12 (polyamide 12) is a semicrystalline aliphatic polyamide engineering thermoplastic, CAS 24937-81-3. It is supplied in primary forms such as pellets and powder rather than as a finished fabric.

How does nylon-12 differ from other nylon types?

Nylon 12 has a long aliphatic repeat unit, giving lower moisture uptake and greater flexibility than nylon 6 or nylon 6,6. This makes it well suited to tubing, SLS powder, and powder coatings.

In what form and packaging is bulk nylon-12 supplied?

Nylon 12 is offered in primary forms such as molding pellets and polyamide powder for coatings or additive manufacturing. Specify pellet versus powder grade and your application; bulk quantities ship with a CoA and SDS.

What HS code applies to nylon-12?

Nylon 12 in primary forms is classified under HS 3908.10, polyamides including PA-12. Confirm the destination tariff line with your customs broker.
