Description
water-soluble forming foil
Physical properties:
Polyvinyl alcohol is excellent adhesive. It has high tensile strength and flexibility. These
properties are depending on humidity, as the polymer absorbs water. Water acts as a plasticizer,
PVOH loses its high humidity, but gains elasticity.
- Perfect, when mechanical components are no longer
can be removed
- Simple to use
- Complete set
- Cheaper than "water-soluble" paper
- Dissolution into molecular components
- Approval of the nuclear industry
