This invention relates to cellulose ester compositions cable of being calendered. The invention also relates to calendered films or sheets comprising the cellulose ester compositions and processes for calendering the cellulose compositions.

A cellulose ester composition with heat distortion temperatures greater than 90 C. is provided comprising at least one cellulose ester and optionally at least one plasticizer. The cellulose ester compositions are useful for making articles such as eyeglass frames, automotive parts, and toys are also provided.

The present application discloses cellulose ester compositions that are plasticizer free that can be processed at higher temperatures with reduced degradation. The cellulose ester compositions disclosed are useful for the preparation of articles, for example eyeglass frames, automotive parts, and toys.

A method for producing bone grafts using 3-D printing is employed using a 3-D image of a graft location to produce a 3-D model of the graft. This is printed using a 3-D printer and a printing medium that produces a porous, biocompatible, biodegradable material that is conducive to osteoinduction. For example, the printing medium may be PCL, PLLA, PGLA, or another approved biocompatible polymer. In addition such a method may be useful for cosmetic surgeries, reconstructive surgeries, and various techniques required by such procedures. Once the graft is placed, natural bone gradually replaces the graft.

Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.

The present invention relates to new acid resistant hard pharmaceutical capsules, a process for their manufacture and use of such capsules particularly but not exclusively for oral administration of pharmaceuticals, veterinary products, food and dietary supplements to humans or animals. The capsules of the invention are obtained by aqueous compositions comprising a water soluble film forming polymer and gellan gum in a mutual weight ratio of 4 to 15 weight parts of gellan gum for 100 weight parts of film forming polymer.

Provided is a resin composition containing: a cellulose acetate in which the weight average polymerization degree is 120-330 and the degree of substitution of an acetyl group is 2.10-2.60; a (meth)acrylic polymer having a weight average molecular weight of 1000-30000; and a plasticizer.

Disclosed are a lyocell material for a cigarette filter and a method of preparing the same, wherein a crimped tow is manufactured using a lyocell multifilament including low-strength lyocell monofilaments, and thus the ultimately prepared lyocell material for a cigarette filter can exhibit low strength, thereby increasing processing efficiency during the manufacture of the cigarette filter.

Reactive additive manufacturing compositions with low amounts of noncombustible materials are provided, as well as methods of making and using the compositions. The compositions comprise two or more reactive components and a filler.

A filtration barrier comprises at least one barrier layer which includes polymeric nanofibers interlaced with microfibers, and at least one substrate layer which includes polymeric microfibers. The filtration barrier can be made by electrospinning process.
