PU drying temperature depends on hardness. 60A-80A drying temperature is 90-100 degrees 85A-98A drying temperature is 100-105 degrees 60D-71D drying temperature and 105-110 degrees drying time is 3-5 hours.

LCP

Each company has different drying temperature and forming temperature for different varieties. For example, the best forming temperature of EI series of Japanese Poly Company is 340-370, and the upper limit of 365 degrees is not more than 30 minutes.

PA Properties

Crystalline thermoplastics have obvious melting point, Nylon 6 Tm is 220-230 C, Nylon 66 is 260-270 C. Nylon itself has water absorption base, so it must be dry before forming. If the temperature is too high and dry, nylon particles will change color.

PC/ABS

The specific gravity is generally 1.15, the water absorption is 0.2%, the shrinkage is 0.4-0.6, and the hot deformation temperature is 120%. The drying temperature should be 100, and the drying temperature should be 100-110 degrees for 3-4 hours.
