Centrifugal Cassette with Molded Insertable Valves
Provided is a centrifuge cassette assembly (800) for separating a fluid and related method of manufacture. The cassette assembly includes a first chamber, a second chamber (308), a fluidic channel (808) creating a fluid connection between the first chamber and the second chamber, at least one molded insertion valve (600, 700) configured to control the flow of fluid in the fluidic channel and a heating element (802) for actuating the at least one molded valve. Further provided are Normally Open Valves (NOVs) (700) and Normally Closed Valves (NCVs) (600) which are capable of insertion into, and which control the fluid flow of, the centrifuge cassette assembly.
Heating device for a heating and sealing system
A protective packaging formation device is disclosed herein. The device includes an inflation assembly that directs fluid between first and second overlapping plies of a web material. The device also includes a sealing mechanism that includes an arcuate web-support surface. The web-support surface includes a heater that defines a heating zone that is operable to heat the plies to create a longitudinal heat seal that seals the first and second plies together as the web is driven over the heating zone in a downstream direction. The web-support surface also includes a cooling zone disposed downstream of the heating zone operable to allow the heated plies to cool at the longitudinal heat seal as the web is driven over the heating zone in a downstream direction, such that the cooled longitudinal heat seal retains the fluid between the plies.

CONTINUOUS OPEN FOAM POLYMER SHEET METHOD
A polymeric sheet, at least partially cross-linked and/or foamed, having a substantially open cell foam structure is described. A continuous method of manufacturing of an at least partially cross-linked, open cell foamed polymeric sheet is also described.
EVA COMPOSITIONS FOR FOOTWEAR
A polymer composition may include one or more ethylene-vinyl acetate (EVA) copolymers in an amount ranging from 65 to 95 wt %; and an elastomer in an amount ranging from 5 to 35 wt %. Articles prepared from such polymer composition may include shoe soles, midsoles, outsoles, unisoles, insoles, monobloc sandals, flip flops, full EVA footwear, or sportive articles.
Shape memory products and method for making them
A method for producing a heat-shrinkable product is provided. First, a polymer composition containing a polymer, a crosslinking agent and a micro-encapsulated foaming agent uniformly dispensed therein is melt mixed. The foaming agent has a peak activation temperature which is higher than a temperature of the melt mixing. Next, the polymer composition is injection molded into a molded product. This carried out at the peak activation temperature to activate the foaming agent. Then, the molded product is crosslinked within the mold.
Antifog polyester lidding film for CPET trays
The present disclosure is directed to peelable, heat-sealable lidding films for containers of diverse polymer compositions storing various products such as foodstuffs and pharmaceuticals. The lidding films disclosed herein can be heat-sealed to crystalline polyester trays (CPET), easily peeled, and contain improved antifogging performance by incorporating a non-migratory antifogging additive into the heat sealable layer of the film without deteriorating seal strengths.
Lightweight thermoplastic soles
An EVA sole having an upper face and a bottom, comprising an inscribed channel and a plurality of recesses positioned on the upper face, a TPU material disposed of within the inscribed channel, and a nylon stabilizer, which is bonded to the upper face inside of the inscribed channel.
Three dimensional footwear component and method of manufacture
A 3D foam component for an article of footwear and a method for manufacturing a 3D foam component for an article of footwear is provided. The method includes a sequential deposition of liquid droplets of liquid polymer material onto an object carrier. A blowing agent is introduced to the molten polymer prior to or sequentially with or after the discharge of a liquid droplet. The resulting component includes a plurality of foam pellets formed by the expansion and cooling of droplets of liquid polymer material injected with the blowing agent.
TUBE SKIRT DECORATED WITH AN ATTRACTIVE LATERAL WELDING
A flat strip 1, suitable for forming a tube flexible skirt, comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 consisting of a series of polymeric layers and comprising a sealable inner layer 14 at the lower surface 20 of the strip 1, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1 and a decorative layer 8, 9.
The primary film 16 comprises means for stabilizing the strip 1 and protecting the decorative layer 8, 9 against heating.
