Frequently Asked Questions
What is PVOH 8825RF?
PVOH 8825RF, as an anionically modified polyvinyl alcohol that has been subjected to specific treatments or the addition of other components to change its original properties to meet the needs of a particular application. This modification may involve chemical modification, physical modification, or a combination of both and is designed to optimize certain properties of the polyvinyl alcohol, such as enhanced mechanical strength, improved solubility, improved thermal stability, etc. The mechanical strength of PVA films produced using this particular PVOH variant increases proportionally with the degree of polymerization or alcoholization.
What is PVOH 8825RF used for?
PVOH 8825RF is designed for the production of biodegradable PVA films. It can be compounded with conventional PVOH to reduce costs and with PVOH 728F to improve the overall performance of the PVA film.
How is PVOH 8825RF packaged and stored?
Packaging: Sealed with
materials
with
moisture-proof properties,
weight
25kg/bag.
Storage：The
storage place should be
kept dry,
cool
and ventilated, avoiding
direct
sunlight and high
temperature.
How is PVOH 8825RF produced?
The polyvinyl alcohol is first mixed with an alcoholizing agent and partially alcoholized; then, the partially alcoholized PVOH is subjected to post-treatment, such as neutralization and washing, to remove unreacted alcoholizing agents and by-products. After removing impurities from the product, the purified PVOH 823G is adjusted to the desired particle size range by processes such as grinding or crushing. Finally, the product is dried to remove excess moisture to ensure product stability and storage.
What are the safety precautions for the use of PVOH 8825RF ?
PVOH 8825RF itself is a
non-toxic,
odorless, non-polluting,
and
environmentally friendly
product.
However, when using,
appropriate
protective equipment such
as masks
and
gloves should be
worn, and the
operating instructions in
the
product
manual should be
followed.
In addition, hazardous
situations
such
as fire or explosion may
occur
under
certain specific
circumstances, such as
exposure to
high temperatures and
sources of
ignition, so ensure that
the storage
environment is away from
sources
of
ignition and
high-temperature
areas.
