Is PEF foam hard or soft?

Let’s introduce this first:

PEF foamed cotton is non-toxic and odorless. The secondary foaming has low density, light weight, and good sound insulation, heat insulation, waterproof, and buffering. Performance, one-time foaming has good physical strength, good oil resistance, solvent resistance, aging resistance, sound insulation, heat insulation, waterproof and buffering properties.

Main applications: automotive electronic parts, air-conditioning and refrigeration accessories, cold storage insulation materials, sealing buffer parts for machinery and equipment, heat-setting parts, various precision

instruments, medical tools, measuring tools Packaging lining, etc.

The hardness should be low
