High viscosity and heat resistant Polyamide 12 for extrusion and injection molding
DAIAMID® L2140 is Polyamide 12 with a heat stabilizer for injection molding and extrusion molding such as wire coating.
Polyamide 12 has the lowest water absorption in polyamides, so this grade maintains excellent dimensional stability even in high humidity environments.
It also has excellent features such as toughness, abrasion and chemical resistance.
This grade is a cylindrical pellet in a moisture-proof bag and you can use it immediately after opening.
The quality guarantee period is separately specified.
