  • Phase separators and cores and enclosures.
  • Discs, rings and similar.

This product, like all those manufactured starting with pure cellulose is sensitive to moisture, consequently, once extracted from its original wrapping it must be kept in a dry place away from sources of heat including direct exposure to sunlight. Do not stack directly on the ground without using Pallets. For long storage periods, PSP 3052 must be protected with plastic to prevent absorption of moisture and deformation of the material.
