Sekisui Specialty Chemicals has been producing high quality polyvinyl alcohol polymers and copolymers since1959. Selvol Polyvinyl Alcohol is both a
non-toxic and environmentally friendly water-soluble polymer. Selvol PVOH is produced at one of Sekisui’s three ISO certified manufacturing plants and is distributed to global customers manufacturing products for the paper, adhesives, personal care, oil and gas, emulsions, construction, textiles, and other specialty applications. Sekisui Specialty Chemicals offers a comprehensive line of Selvol products to meet the exact needs of customers. Each lot is meticulously tested to ensure high quality, tight specifications, and optimal performance. Sekisui’s Houston Technology Center in Houston Texas USA provides technical support to companies
worldwide. Working closely with customers, the scientists and engineers at HTC identify needs in the market to develop tomorrow’s innovative products. HTC has helped
develop products ranging from improved paper coatings and oil resistant food wrappers to films that resist degradation and personal care products. HTC’s pilot capabilities, fully equipped testing laboratory and
formulation experts are available to Selvol customers. The professionals at Sekisui Houston
Technology Center have created the following video to demonstrate proper
handling cooking and storage of Selvol polyvinyl
alcohol. This is a general guide, specific conditions and results may vary.
Contact Sekisui Houston Technology Center with any specific questions Selvol granules can be purchased in 25
kilogram bags, or super sacks. Or by truckload or rail car. For specific instructions on rail car
receipt, please see the bulk handling guide available on the Sekisui Specialty Chemical’s website. Bags and super sacks can be stored in their original packaging at ambient temperatures for up to 5 years. Dry storage conditions
are key to solubility because granules can clamp and become
insoluble exposed to moisture clumping can also occur through compaction,
either during transportation or storage. Conditions for dissolution are governed
by hydrolysis, molecular weight, particle size, and crystallinity. The grade used in this demonstration will be Selvol 103. Please refer to the solution
preparation guide available online for detailed instructions on all
grades. First, ensure that the proper safety equipment is worn. To safely cook Selvol polyvinyl alcohol,
following PPE is necessary a lab coat, safety glasses, thermal gloves
for handling hot equipment and solution and latex or nitrile gloves for handling
defoamer and biocide. the preferred heating method for
solubilizing fell polyvinyl alcohol is by steam jacket direct steam injection can also be
sufficient polyvinyl alcohol can generate phone depending on the degree of hydrolysis
and method of preparation if necessary add a defoamer to the water
before mixing in the silver particles the most critical step in effectively
dissolving sellable is complete aspersion on the particle than unheeded
water begin with water at room temperature
about 25 degrees centigrade ensure proper education and good service
move into the water as the surface have some polyvinyl
alcohol grades can swell quickly and come together upon contact with water variable speed overhead mixers are the
preferred agitators magnetic stirrer plates or cans during
will not provide adequate education for this process add the cell granules to the water using
the recommended addition rate listed in the solution preparation guidelines monitor the agitation to prevent air
from becoming in train in solution insure the cell granules do not sit on
the surface of the water or fall to the bottom of the tank once
the particles are well dispersed in cool water usually five to ten minute the suspension can be heated will only
keep the solution to the minimum could temperature detailed in the solution
preparation guide cover the slurry to minimize water loss
Paul Cook temperature for a minimum of 30 minutes to allow complete dissolution allow the solution a cool under
agitation then filter using a minimum 70% maj four to 10 micro screen to catch any undissolved particles use a
biocide the solution will be stored for more than 24 hours specific recommendations for the Bombers
biocides and other additives can be found in the solutions preparation guide along with alternate equipment could
procedure and other additives please contact Becky theories Houston
Technology Center for assistance with non standard procedures were any cooking issues sellable
polyvinyl alcohol is relatively easy to clean up there the cooking vessel with the clean
water heat back to cook temperature according to the solutions preparation
guide and agitate for a minimum of 30 minutes depending on the grade in 100 tration a
polyvinyl alcohol this process might need to be repeated
for a complete between lenders or detergents should not be
necessary do not use bleach because cellmark polyvinyl alcohol is
non-toxic non-hazardous and has a little biological oxygen
demand and both the solution and rinse water
can be safely disposed at their most our system please check with local municipalities
for clearance Sekisui specialty chemicals is proud to provide support
