[edit] Other uses

PVA is also used as a spray on mold release in some types of plastics fabrication, especially glass reinforced polyester or epoxy resin. Its water soluble and biodegradeable properties make it easy to completely remove from the molds and fabricated parts simply by washing with water.

PVA is widely used as binder to improved the green strength and pressability in soft ferrite materials. PVA together with plasticizer has an great impact to develop green strength in intricate part made with soft ferrite material.e.g. MnZn Ferrite, NiZn Ferrite

PVA is used in the biomedical research field as a salt bridge (when saturated with a supporting electrolyte) in microscale electrochemical applications. It is also used as a supporting medium for cryomicrotomy sectioning of tissue for histological study.

There are two types of "school glue" sold in retail stores. One type is white (which may be either polyvinyl acetate or a blend of polyvinyl acetate + polyvinyl alcohol). The other type (Example: 3M Scotch 'Clear Glue with 2-Way Applicator') is clear and colorless. Is the clear one an aqueous solution of polyvinyl alcohol? If not, then what is that stuff? I'm curious.--Zymatik 15:33, 24 June 2007 (UTC)

[edit] Fishing

I removed this line from the fishing section:

PVOH is odorless and nontoxic, but can undergo pyrolysis at high temperatures. There are varieties approved by the FDA for direct food contact.

The first part (about odor & toxicity) I put in the Properties section. The second part about the FDA doesn't make sense - what "varieties" are being referred to? This should be corrected/clarified and put back. Dhollm 10:07, 25 April 2007 (UTC)
