A cellulosic particle contains cellulose as its base constituent, and the percentage water absorption of the cellulosic particle measured by method B in ISO 15512:1999 is 11% or more and 20% or less.

The present invention is directed to impact resistant and/or thermally insulative coating compositions for protective packages. Particularly, the protective packages include envelopes, pillows and Gusseted bags that house fragile and/or perishable objects during transport or mailing. The coating composition, upon heat or radiation trigger, expands at least 2500% in volume. The protective packages coated with the coating composition provide impact resistance, high strength, thermal insulation and light-weighting.

A method for manufacturing an anti-aging rubber is disclosed. The method includes the following steps: adding and mixing one of a carbon tube material and a graphene material into a rubber-processing oil consistently to obtain a rubber-reinforced composite; and mixing the rubber-reinforced composite with a main rubber, a filler and a crosslinking agent.

A gel composition is herein disclosed. According to one embodiment, the composition comprises a (i) a styrenic block copolymer, (ii) an oil; and (iii) optional additives; wherein the styrenic block copolymer comprises: a diblock polymer having a monoalkenyl arene block, designated A, a conjugated diene block, designated B, an isoprene attachment, designated i, and wherein the styrenic block copolymer can have structure ABi or iAB; the isoprene attachment i is substantially unsaturated and the conjugated diene block B is substantially saturated. The gel composition before curing exhibits thixotropic behavior, and the gel composition after curing is either solid or has a viscosity at 25 C. at a shear rate of 20 s.sup.1 of at least 30000 mPa.Math.s.

Provided are use of a rare earth amino acid complex, a polylactic acid composition and a preparation method thereof. The rare earth amino acid complex is formed by complexing a rare earth metal ion with an amino acid; a rare earth element corresponding to the rare earth metal ion is one or more selected from the group consisting of lanthanum, cerium and samarium; and the amino acid is at least one selected from the group consisting of proline, L-phenylalanine, tyrosine and tryptophan.
